Arthur Frederick Sheldon

Arthur Frederick Sheldon (1867 – 1935) was an American educator, publisher, and business philosopher best known as the founder of the Sheldon School of Scientific Salesmanship and as an early intellectual architect of Rotary International. A pioneer in applying psychological principles to commerce, he developed what he called the "Science of Successful Salesmanship," a correspondence-based system that at its height enrolled more than 250,000 students worldwide. Through his magazine The Business Philosopher, Sheldon advanced a philosophy that linked ethical service with commercial success, coining the Rotary motto "He Profits Most Who Serves Best." His work helped shape early twentieth-century thought on sales training, business ethics, and vocational service, leaving a lasting imprint on both commercial education and civic organizations.

Arthur Frederick Sheldon was born on May 1, 1868, in Vernon, Michigan, the son of Seth Ellsworth Sheldon and Helen Mary Woodward Sheldon. He was educated in the district schools and graduated from Vernon High School in 1885. Following graduation, he became a country schoolmaster and taught district school for two years.^{[1][2][3][4][5]}

While teaching, Sheldon observed a traveling book agent visiting his school. After calculating that the agent’s commissions were approximately twice his own teaching salary, he sought and obtained similar employment when the local territory became available. He was later sent to Humboldt County, California, where he found that much of the territory had already been canvassed. Noting that the previous agent had been a woman, he concluded that rural districts were likely not fully covered. During the rainy season, when roads were nearly impassable and most agents confined themselves to towns, he traveled into the redwood lumber districts, working among farmers, dairymen, and lumbermen.^[6][1][7][2]

Determined to obtain a university education, he sought to finance his own studies after his father declined financial assistance, telling him that if he were worthy he would prove strong enough to carry out his plans independently. At the time Sheldon owned a two-year-old colt which he had personally raised. He sold the colt for two hundred dollars and used the proceeds to attend the State Normal School before enrolling at the University of Michigan to study law.^[8]

He received the degree of LL.B. in 1892, graduating with high standing. During his time at the University of Michigan he was a charter member of the Kappa Sigma fraternity, was elected president of the Webster Society, and served as quiz master for the junior and senior law students.^[9][10][5]

After graduation Sheldon entered the employ of the Werner Company, working as a traveling salesman selling educational books door to door. During this period he traveled widely, selling works such as the Encyclopedic dictionary, Encyclopedia Americana, Waldorf Cook Book, Webster's Dictionary, Encyclopædia Britannica, Library of the World's Best Literature and his best seller, Happy Homes and the Hearts That Make Them. He canvassed remote territories, including Wyoming ranch country, at times traveling by bicycle and later exchanging it for a cow pony in order to reach isolated customers.^[5][1]

Sheldon proved so successful that the Syndicate Publishing Company placed him in charge of a branch office, where he was responsible for training and managing young book agents for field work. In 1896 he was promoted to general sales manager in Chicago, exercising supervision over offices throughout the United States and Canada.^[11][12]

During this period, one of Sheldon’s closest associates and most effective field agents was Frank H. Dukesmith. Together they directed several campaigns and promotions that achieved notable success for the company. Both men were serious students of what was then coming to be called "salesmanship." They analyzed the causes of success and failure in the field and came to believe that salesmanship rested upon principles that could be systematically organized and taught. Sheldon was influenced by the theoretical psychology he had encountered during his university years and by Blackstone’s systematic treatment of the common law of England. He rejected the prevailing commercial doctrine of "let the buyer beware," arguing instead that profit must be joined to service in the public interest. His growing interest in the "new psychology" then gaining prominence in Chicago led him and Dukesmith to form an association with Dr. Herbert A. Parkyn of the Chicago School of Psychology.^{[13][14][15][12]}

For several years Dr. Parkyn had been developing the application of suggestion to advertising, and there was increasing demand among students at his Chicago School for systematic instruction in its commercial use. Dr. Parkyn regarded advertising and salesmanship as powerful suggestive forces in modern life, capable of shaping public thought for good or ill. He, however, chose not to incorporate such training formally into the curriculum of his medical school, seeking to avoid public controversy or accusations that he was employing hypnotic methods in the marketplace.^[16][17]

Instead, Parkyn supported the organization of a separate school grounded in the principles of suggestion and aimed at elevating professional standards and promoting greater integrity within salesmanship. In the spring of 1898, the Chicago School of Salesmanship was founded at 269 Dearborn St in the Boylston Building. It was the first commercial school in America dedicated specifically to teaching the science of salesmanship.^{[18][19][20][21]}

Frank H. Dukesmith prepared the course manual, titled The Philosophy of Salesmanship, drawing upon ideas he and Sheldon had been developing as well as the science of suggestive psychology taught at Parkyn’s Chicago School. W. J. Chatterton, a close associate of Parkyn who had assisted in opening affiliated branches of the Chicago School of Psychology in other cities, was brought onto the faculty as instructor in psychology.^[21][22][23]

This first incarnation of a school devoted to the science of salesmanship lasted only about six months and had ceased by September 1898. Sheldon, who had been working in support of Dukesmith in connection with the school, was soon offered an opportunity by his uncle, Charles Cyril Post, to relocate to Sea Breeze, Florida, and establish a publishing company to distribute literature associated with the hugely successful mental science colony founded there by Post and his wife, Helen Wilmans Post. Dukesmith, who had served as the public face of the school while also working for the Obenchain & Boyer fire extinguisher company, was bought out by Sheldon and Parkyn, who retained ownership of the course manual and the school’s name. The following month, Dukesmith purchased a fifty-acre farm near his hometown in West Virginia for $3,750.^[24][25]

In 1898 Sheldon moved with his wife and child to Sea Breeze, Florida, where his uncle Charles Cyril Post and Helen Wilmans Post, had established a mental science colony.^{[26][27][28][29]}

Helen Wilmans Post was a prominent New Thought author, and advocate of mental science who taught that mind was the governing force behind health, character, and material conditions. Through her magazine Freedom, she had a large medical practice of what was termed "absent treatment," a system of healing conducted through directed mental concentration rather than physical presence. Sheldon's uncle, Charles Cyril Post, was a former newspaper publisher and political figure who was the principal associate in the colony. He assisted in managing its publications, business affairs, and organizational expansion.^[30]

The Mental Science Association was formed to promote and disseminate the teachings of mental science through a coordinated effort. Its national headquarters operated from Sea Breeze, which functioned as both a residential colony and the administrative center of the movement. The Association encouraged the creation of affiliated local Temples in major cities across the United States. During this period Temples were organized in New York, San Francisco, Los Angeles, Seattle, Portland, Chicago, St. Paul, St. Louis, and Cleveland. In 1899, Sheldon founded the Sheldon Publishing Company to distribute literature associated with the Mental Science Association.^[31][28][29]

Sheldon served on the Central Executive Committee of the Association alongside his aunt and uncle, as well as other New Thought luminaries such as Frederick W. Burry, Charles F. Burgman, Eugene Del Mar, and Frank Newland Doud (also a graduate of the Chicago School of Psychology). The organization convened national gatherings to consolidate its membership and extend its reach. A major convention was held at Sea Breeze in 1900, drawing representatives from affiliated branches and from independent mental science circles.^[29]

In 1901 the Sea Breeze mental science community led by Helen Wilmans Post came under investigation by the United States Post Office Department in connection with her promotion of “absent treatment” by mail.^[27][28]

Patients paid monthly fees and were instructed to concentrate mentally upon her at appointed times while she directed healing thought toward them. Postal authorities concluded that the volume of paying patients was too great for her to provide individualized treatment, asserting that there were not sufficient hours in the day for her to direct attention to each case.

After a formal hearing, the Post Office issued a fraud order in September 1901 barring Wilmans from use of the mails. Because the mental science community founded at Sea Breeze depended heavily on mail-based subscriptions and treatment remittances, the order effectively dismantled the operation and brought the colony’s organized activities to an end.^[27][29]

Following the postal action, Sheldon and his family left Sea Breeze and returned to Chicago. There he resumed his publishing work, accepting a position as manager with the publishing house of A. C. McClurg & Co.^[1]

In 1902 Sheldon reconnected with the Chicago School of Psychology and its founder, Dr. Herbert A. Parkyn, to establish a school devoted specifically to scientific salesmanship. The enterprise began modestly while Sheldon was still serving as a manager for A. C. McClurg & Co. A small room was sublet in the McClurg building where clerical help was shared, and on July 24, 1902, the first regular student was enrolled.^{[32][17][33][34][35][36][1][2][37]}

From the outset, growth depended heavily on Sheldon’s personal lecture tours. He traveled extensively to advertising clubs, business associations, and commercial gatherings across the country, presenting the principles of scientific salesmanship and generating enrollment for the correspondence course. This pattern of continuous travel and public lecturing became a defining feature of the school’s expansion.^{[38][39][40][41][42][43][44][45]}

By January 1903 the school had expanded into additional offices in the building, and within a year nearly one thousand students had registered for correspondence instruction. Enrollment increased at a rate of more than one hundred students per month, reflecting growing national interest in scientific salesmanship training.^[46]

The course manual was organized around the systematic study of suggestion and the cultivation of disciplined mental habits. It included instruction under headings such as "Yourself and Your Powers," "Character and Health Building," "Mental Culture," and "Psychology." The manual made clear that no diploma would be awarded unless the "important section on Suggestion" was successfully completed.^[47][35]

Sheldon authored several portions of the course himself, while other sections incorporated lectures from established businessmen. The central feature of the curriculum was the extended lesson series titled "Suggestion in Salesmanship." This section closely followed the psychological framework developed by Dr. Parkyn at the Chicago School, drawing upon material previously presented in his books and in Suggestion magazine. The manual’s review questions explicitly referenced Parkyn’s teaching, including the question "Give five methods for strengthening the Will and explain why such training directly affects character. What does Dr. Herbert Parkyn say concerning the cultivation of the Will?"^{[48][47]: 185-186}

Sheldon’s Suggestion in Salesmanship closely followed the psychological system of Suggestive Therapeutics. The lesson series restated the three laws of suggestion: that the voluntary mind is governed by reason and the senses; that the involuntary mind becomes receptive as voluntary resistance is quieted; and that repeated suggestion tends to crystallize into belief and action.^{[47]: 181-238}

The course repeated core suggestive teachings, including the effectiveness of suggestion given before sleep, the continued activity of the mind during rest, and the shaping of habit through repeated thought. It also reproduced the division between general suggestion, affecting the whole personality, and specific suggestion directed toward particular habits, using the same analogy of general tonics versus targeted remedies.^[35][36]

Sheldon reiterated the doctrine of mental causation, asserting that every action originates in thought and illustrating this principle with examples of buildings, machines, ships, and laws as creations first conceived in mind. His definition of auto-suggestion paralleled the Chicago School teachings, describing it as a suggestion arising within one’s own mind from thought or sensation, whether real or imagined. The lessons further emphasized that intense attention heightens suggestibility, applying this principle directly to the sales interview, where a customer’s focused attention increases the effectiveness of suggestion.^[47][49]

The Sheldon School quickly became known throughout the country as the preeminent institution for learning the modern techniques of scientific salesmanship. Its methods, rooted in psychology and mental training, were adopted by major corporations, and it became common to see the phrase "a Sheldon School graduate preferred" in employment advertisements. Arthur F. Sheldon traveled extensively, delivering lectures and expanding the school’s reach across the United States.^[50][51][52]

Dr. Parkyn collaborated closely with the Sheldon School in promoting the power of suggestion in business. In his Suggestion magazine, he created a dedicated department titled Business Psychology, edited by Prof. P. J. Mahon, a faculty member at the Sheldon School.^[53] This department covered business-specific adaptations of psychological methods, such as the use of auto-suggestion for developing confidence, concentration, optimism, and ethical character in professional life.^[54]

The school was featured in many editorials and articles in Suggestion that praised its approach to sales training and presented it as a direct extension of the larger Suggestion movement.^[53][55][56]

In 1904 The Business Philosopher was launched as the primary vehicle for disseminating the school’s "Science of Business" to a broader audience. Published by the Sheldon Publishing Company, the magazine was intended to present Sheldon’s business principles in clear and accessible language for working professionals. Subtitled a "Periodical of Power," it promoted what it described as the power to earn, power to acquire, power to use, and power to enjoy through the application of natural and ethical laws to commerce.^[57][58]

Each issue addressed both practical and philosophical aspects of business life. Articles covered individual development, including brain-building, memory training, health, nutrition, and character formation. The magazine also featured instruction in salesmanship, retail and office methods, advertising strategy, and persuasive business correspondence. Additional topics included organization, cost control, efficiency, the study of human nature in trade, and the elimination of waste. Central to the publication was Sheldon’s "Philosophy of Service," which maintained that service, rather than mere profit-seeking, formed the only lasting foundation of commercial success.^[57][58]

The connection between the two institutions was reinforced through coordinated publishing and promotional activity in The Business Philosopher and Suggestion. Each periodical regularly carried advertisements for the other, including bundled subscription offers. One prominent promotion offered a year’s subscription to The Business Philosopher together with a copy of Parkyn’s Auto-Suggestion at a reduced price, presenting the volume as an essential complement to the school’s psychological training and business instruction.^[60][58][61]

The connection was also evident in the school’s adoption of slogans Parkyn had long employed in his own publications and national advertising campaigns. Phrases such as "Do it now," "Thought takes form in action," "I can and I will," and "Thinker" had appeared regularly on the covers and pages of Suggestion, in Parkyn’s books, and in his newspaper advertisements campaigns. These same expressions were incorporated into Sheldon’s editorials, course lessons, and promotional materials, reinforcing the continuity between Parkyn’s earlier work in suggestive advertising and the messaging of the Sheldon School.^[57][62][60]

The Science Press operated as the publishing arm of the Sheldon School and was directed by Edward E. Beals, a graduate of Parkyn’s Chicago School. It functioned alongside the school’s correspondence program, issuing The Business Philosopher as well as books aligned with the school’s emphasis on mental discipline and ethical service in business.^[58]

In 1905 The Science Press published Dr. Parkyn’s Auto-Suggestion and Stanley L. Krebs’s The Law of Suggestion, which were marketed as companion volumes. Krebs had been both a graduate and instructor at the Chicago School. Shortly thereafter, the press released James Allen’s As a Man Thinketh, which was promoted prominently with Dr. Parkyn’s well-known axiom "thought tends to take form in action" featured in its advertising.^[60][63]

Beals later authored The Law of Financial Success, a widely popular work that was anonymously co-written with William Walker Atkinson, one of Parkyn’s closest collaborators and protégés. Beals subsequently acquired the publishing rights to Atkinson’s earlier works through his Fiduciary Press and continued issuing new Atkinson titles under The Progress Company. In 1922 he would collaborate again with Atkinson on the twelve-volume Power Book series.^{[64][65][66][67]}

In 1905 Sheldon established a London branch, extending his system of scientific salesmanship to the United Kingdom and the British Empire. The office was located in High Holborn and served as the headquarters for the school’s European and colonial operations. The London branch offered the same correspondence courses and promoted scientific salesmanship as a universal system of business training. By 1910 it had its own management and local editions of The Business Philosopher, enrolling students across the United Kingdom, Australia, and South Africa. At its peak, the worldwide reach of Sheldon’s correspondence model had a student body exceeding 250,000.^[68]

For much of the twentieth century, the AIDA model of Attention, Interest, Desire, Action, has widely been attributed to E. St. Elmo Lewis. That attribution rests primarily on a statement published in 1925 by Edward K. Strong, Jr. who asserted that Lewis had formulated much of the model in 1898 and then added the instruction to "get action" later. However, no primary document from 1898 was cited to support the claim. While marketing textbooks and academic works over the years have repeated this attribution without verification, modern historical research has challenged this narrative and demonstrated that no writings by Lewis from the late 1890s contain the AIDA formulation. Lewis’s earliest work from 1899 referred to catching the eye of the reader, informing him, and making a customer of him, but there is no documentary evidence of Lewis using the terms of the sequence before 1908.^[69]

By contrast, printed evidence from Chicago in 1898 shows that Arthur F. Sheldon and Frank H. Dukesmith were already using several of the elements in a defined mental progression. When the Chicago School of Salesmanship opened in May 1898, its curriculum described selling as a psychological process requiring the securing of attention, the creation of desire, and the obtaining of the order. Newspaper articles of the school’s opening in 1898 also outlined these elements explicitly. The material used for the course manual had been under development for at least a year, placing the structured formulation of several of the elements in existence as early as 1897.^[71][70]

After Dukesmith was bought out of the Chicago School of Salesmanship in late 1898, the framework was carried forward rather than newly invented for the relaunch of the school in 1903. In the first edition of The Science of Successful Salesmanship (1903), it states that "the mind of the customer must pass along a mental path of four steps: attention, interest, desire and resolve to buy.”^[71]

The "Will" is defined as the faculty of "decision and action" and it's repeatedly emphasized that no sale is complete until action is secured. Throughout the text, the movement from attention to interest, from interest to desire, and from desire to decision and action is described as a fixed psychological law governing every successful sale.^[71]: 13

The same structure appears independently in Dukesmith’s later work. In 1903 he founded the magazine Salesmanship in Meadville, Pennsylvania, aimed at advancing the science of salesmanship. Its editorials repeatedly used the progression of attention, interest, desire, and conviction in model form, presenting the sequence as the normal mental order through which a sale must pass^[72][73]

Sheldon is credited with expanding the classic AIDA model into what he termed AIDAS. He introduced the formulation in his 1911 book Successful Selling. His addition of the fifth element, Satisfaction, shifted the emphasis from securing a single transaction to cultivating lasting commercial relationships within what he described as a broader "Science of Business Building."^[74][75][76]

Sheldon taught that the buyer’s mind passes through identifiable stages in the process of purchase. First, favorable attention must be secured so that the prospect is receptive to the presentation. Attention then develops into interest, often strengthened through demonstration or illustration. Interest deepens into desire, at which point objections must be addressed so that the customer feels genuine need for the product. Action follows when the prospect commits to purchase. Sheldon argued, however, that the process did not end there. The final and essential stage was satisfaction, achieved by reassuring the buyer after the sale and ensuring that expectations were fulfilled.^[76]

In The Business Philosopher, Sheldon maintained that satisfaction was the foundation of enduring success. A single sale, he argued, had little long-term value unless it produced permanent satisfaction and repeat patronage. He framed the seller’s role as that of a counselor rather than a manipulator, asserting that profit was the natural byproduct of service.^[76]

In 1909 Sheldon relocated his school from rented offices in Chicago to an extensive tract of approximately 600 acres in Rockefeller, Illinois, to realize his dream of a "Business University." Drawn to the Lake County area, Sheldon acquired several parcels of land, including the former Norton homestead. His arrival marked a significant transformation for the small community. Through local influence and promotion, the town’s name was changed from Rockefeller to Area, Illinois, the name derived from the school’s guiding principles: Ability, Reliability, Energy, and Action.^[77][6][33]

Sheldon invested heavily in developing the property. He spent $15,000 to dam a boggy slough known as "Mud Lake," creating a mile-long spring-fed lake that became a central feature of the grounds. The expanding school also became a major local employer, with nearly 200 residents working in its offices and printing facilities. The campus grew to include many modern brick buildings that housed administrative offices, shipping operations and the school’s large printing presses and production facilities.^[77][33]

The Area property functioned not only as an educational center but as a community environment. Evening instruction was offered in subjects such as bookkeeping and shorthand, while the grounds provided recreational opportunities throughout the year, including canoeing, ice skating, and seasonal social gatherings. Sheldon resided on the property in a remodeled house maintaining close oversight of the expanding institution.^[77][33]

Sheldon was a real estate developer as well as an educator. When he purchased the 600-acre tract in Rockefeller he created a master-planned community where he profited significantly from land sales. Sheldon viewed his property as a "Model City" centered around his educational philosophy. To capitalize on the school's fame Sheldon subdivided portions of his 600 acres into residential and commercial lots. He marketed these to his employees, faculty, and local residents who wanted to be part of the burgeoning "Area" community.^[78]

The decline of the Sheldon School of Scientific Salesmanship during the First World War resulted from a convergence of demographic, financial, and international pressures that undermined both its enrollment base and its operating model.^[77]

The school relied heavily on correspondence courses marketed to young men in their twenties and thirties and as the United States entered the war, domestic enrollment declined sharply. Even before American involvement, the outbreak of war in Europe in 1914 disrupted the school’s branch in London, severing communication channels and reducing foreign revenue. The School functioned as a substantial printing and publishing enterprise and wartime conditions brought significant increases in the cost of paper, ink, and postage. At the same time, the institution carried the heavy expense of maintaining its 600-acre campus at Area, Illinois, including buildings, staff, and printing facilities. As enrollment declined and revenues contracted, these fixed costs became increasingly difficult to sustain.^[78][79][77]

By 1918 the school had ceased operating as a major educational institution. Facing financial strain, Sheldon had to liquidate the Area estate. In May 1921 he sold the property to George Mundelein, the Catholic Archbishop of Chicago. Reports placed the sale price between $350,000 and $500,000, a substantial sum for the period. The archdiocese soon converted the property into the University of Saint Mary of the Lake, which became a major Catholic seminary.^[77]

Following the sale, Sheldon relocated his publishing and business activities back to Highland Park. In 1925 the town formerly known as Area was renamed Mundelein in honor of the archbishop who had purchased the estate.^[78]

Sheldon joined the Rotary Club of Chicago in 1908, three years after its founding. At that time the organization functioned primarily as a professional fellowship designed to promote acquaintance and business exchange among its members. Sheldon entered the club already established as an educator and publisher and brought with him his articulated "Philosophy of Service," which held that enduring business success derived from ethical conduct and genuine service to others rather than from competitive advantage alone.^{[80][81][82][2][83][84]}

Sheldon’s most enduring contribution to Rotary was the formulation of its first official motto. At the 1910 Rotary convention in Chicago, he delivered an address in which he declared that only right conduct toward others yields lasting success and concluded with the statement, "He profits most who serves his fellows best."^[80][85][82]

In 1911, at the Rotary convention in Portland, a report Sheldon prepared for the Committee on Business Methods was read in his absence. The report contained the shortened phrase, "He Profits Most Who Serves Best." The delegates adopted the expression as the official motto of the organization, recognizing it as a concise statement of Rotary’s developing purpose.^[85][86]

The motto remained central to Rotary identity for decades. In 1950 Rotary formally approved two official mottoes: Sheldon’s phrase and "Service Above Self." In subsequent years the wording of Sheldon’s original statement was modified for inclusivity, evolving to "They Profit Most Who Serve Best" and later to the present form, "One Profits Most Who Serves Best."^[85][87]

Sheldon’s influence extended beyond the motto. He was instrumental in defining what later became Rotary’s "Vocational Service," one of its principal avenues of activity. He advocated a classification system in which each member represented a distinct trade or profession, thereby ensuring that clubs reflected a broad cross-section of business life. This structure emphasized responsibility within one’s vocation and discouraged direct commercial competition within the same club. He also contributed to early discussions of business ethics within Rotary, advancing the view that commercial practice should be governed by standards as definite as natural laws. Rotary founder Paul Harris later acknowledged Sheldon’s intellectual influence in This Rotarian Age (1935), describing how Sheldon’s conception of business as a science of service shaped the organization’s higher aims.^[80][81][82]

Sheldon is credited with proposing the name "Better Business Bureau." Prior to 1915 the organization had operated in limited fashion under the title “Better Advertising Bureau.” At a meeting in Indianapolis, Merle Sidener, then active in the “Truth in Advertising” movement, remarked to Sheldon that the existing name was inadequate. Sheldon reportedly walked to a blackboard and wrote out “Better Business Bureau,” a broader title that more accurately reflected the group’s expanding mission beyond advertising alone. Sidener immediately endorsed the suggestion, and the name was adopted as the permanent designation.^[88]

Sheldon’s address at the 1921 Rotary Convention in Edinburgh, Scotland, marked a significant moment in Rotary’s international development. It was the first convention held outside the United States, and Sheldon delivered a 45 minute speech articulating the ethical foundations of the movement. The speech received a legendary standing ovation and was later printed as "The Philosophy of Service," for global distribution to schools and institutions as a masterpiece of business ethics.^[89]

Sheldon argued that moral law in business was as certain as physical law, and that service to others constituted enlightened self-interest. Profit, he maintained, was the natural consequence of right conduct rather than its objective. The address reinforced the interpretation of "He Profits Most Who Serves Best" as more than a commercial maxim. He argued that "the way to preserve self is to serve others." He famously stated that "Service to others is the road to self-construction," while pure selfishness leads to "self-destruction."^[89]

Sheldon maintained that every commercial transaction involved reciprocal obligation. The seller, in his view, was not merely an advocate for his own interests but a counselor whose duty was to understand the needs of the buyer and to render genuine service. He rejected the notion that business was a contest of shrewdness or advantage, insisting instead that enduring success depended upon fairness, truthfulness, and constructive cooperation.^[89]

Sheldon defined profit broadly as the betterment of both the individual and the community. Following the convention, Rotary increasingly articulated its mission in terms of "international goodwill and peace" through the "ideal of service," extending the philosophy first expressed in Chicago into a global humanitarian framework.^[90][80][91]

In 1895 Sheldon married Anna Griffiths of Kingston, New York. The couple had three children, one son and two daughters. During the years of Sheldon’s extensive national lecture tours, Anna frequently traveled with him, accompanying him as he promoted the principles of scientific salesmanship and the Philosophy of Service across the United States and abroad.^[4]

Sheldon was a life member of the Chicago Press Club, a Freemason, and an honorary member of several Rotary clubs, including those of Kingston, New York, London, England, and Edinburgh, Scotland. He was also a member of the National Arts Club of New York City. In the late 1920s, after decades of travel and public work, Sheldon and his wife returned to Kingston, New York.^[4]

In his later years Sheldon spent time at a vacation home in Texas due to declining health. He died in 1935 at his home in Mission, Texas. His body was returned to Kingston, New York, for burial.^[92][4][93]
