Robert Berkeley "Bob" Minor (1884 – 1952) was a political cartoonist, a radical journalist, and, beginning in 1920, a leading member of the American Communist Party.
Robert Minor, best known to those who knew him by the nickname "Bob," was born July 15, 1884, in San Antonio, Texas. Minor came from old and respected family lines. On his father's side, General John Minor had served as Thomas Jefferson's Presidential campaign manager; his mother was related to General Sam Houston, first President of the Republic of Texas. His father was a school teacher and lawyer, later elected as a judge, while his maternal grandfather was a doctor.
Despite the notable family forefathers, Bob Minor was not brought up with a silver spoon in his mouth — rather he was the product of what one historian has called "the hard-up, run-down middle class," living in an "unpainted frontier cottage in San Antonio." Minor was unable to begin school until age 10 due to his family's dire financial straits before leaving school at age 14 to take a job as a Western Union messenger boy to help support his family. Minor left home two years later, going to work at a variety of different jobs, including time spent as a sign painter, a carpenter, a farm worker, and a railroad laborer.
In 1904, at the age of twenty, Robert Minor was hired as an assistant stereotypist and handyman at the San Antonio Gazette, where he developed his artistic talent in his spare time. Minor emerged as an accomplished political cartoonist.
Minor moved to St. Louis to take a position as a cartoonist for the St. Louis Post-Dispatch. Minor's work, initially very conventional in form using pen-and-ink, was transformed by his move to the use of grease crayon on paper. Minor gained recognition as the chief cartoonist at the Post-Dispatch and was considered by many to be among the best in the country.
In 1911, Robert Minor was hired by the New York World, where he became the highest paid cartoonist in the United States. His father was on a parallel path of advancement, transformed by a 1910 election "from an unsuccessful lawyer to an influential district judge."
