Best known for lively early-20th-century biographies, this British writer focused on prominent public figures including Marie Corelli, Lord Rosebery, and William Booth. His books have a brisk, admiring style that captures the tone of literary and political biography from the period.

by Thomas F. G. Coates, R. S. Warren (Robert Stanley Warren) Bell
Thomas F. G. Coates was an early-20th-century biographer whose confirmed works include Lord Rosebery, His Life and Speeches (1900), Marie Corelli: The Writer and the Woman (1903, with R. S. Warren Bell), and The Prophet of the Poor: The Life-Story of General Booth (1906).
The surviving records available here say much more about his books than about his personal life. What can be said with confidence is that he wrote about well-known cultural, political, and religious figures, and that his work leaned strongly toward appreciative, personality-driven biography.
Because reliable biographical details about Coates himself are hard to confirm from the sources found, it is safer to remember him through his subjects: a bestselling novelist, a British statesman, and the founder of the Salvation Army. That range suggests a writer interested in fame, public influence, and the lives behind big reputations.
