Leon Greenbaum (1866-19XX) was an American socialist official, writer, lecturer, union organizer and political candidate from Missouri. He is best remembered as the first National Executive Secretary of the Socialist Party of America, serving in that capacity from 1901 to 1902.
Leon Greenbaum was born in 1866 in Philadelphia. He took a variety of jobs as a youth and a young man, working successively as an office boy, retail clerk, stenographer, and traveling salesman. Greenbaum had little formal education, but was a voracious reader and followed the path of self-education.
In 1896, while on a business trip, Greenbaum read the popular populist propaganda tract Coin's Financial School, by W. H. Harvey, later meeting the author. Greenbaum later attributed his attraction to radical politics to the experience.
Greenbaum became active in progressive reform politics during the last years of the 1890s, joining an effort to bring the system of initiative and referendum to Missouri in 1899. By 1900 he had joined the Social Democratic Party of America, for which he was active as a public speaker. He wrote an "economical romance" called Last Days of the Nineteenth Century
Greenbaum was a multi-time candidate of the short-lived Social Democratic Party of America; in 1900, he was the nominee for Lieutenant Governor and in 1901 for mayor of St. Louis. Upon the formation of the Socialist Party of America in 1901, party headquarters were located in St. Louis and Greenbaum was the party's first Executive Secretary. During this time, he was also an organizer for the American Federation of Labor.
During his time as Executive Secretary, Greenbaum oversaw the difficult task of merging 23 loosely affiliated state parties into a national organization. For example, the Social-Democratic Party of Wisconsin refused to apply for a national charter and remained in the party "with all of the privileges but none of the obligations". There was also often conflict in deciding how to engage with the existing trade union and labor party movements.
In later years, Greenbaum was greatly involved with an offshoot of the Christian Science movement, writing numerous pamphlets on behalf of the religion.
