Robert Green "Bob" Ingersoll (August 11, 1833 - July 21, 1899) was a Civil War veteran, American political leader, and orator during the Golden Age of Freethought, noted for his broad range of culture and his defense of agnosticism. He was nicknamed "The Great Agnostic."
Robert Ingersoll was born in Dresden, New York. His father, John Ingersoll, was an abolitionist-leaning Presbyterian preacher, whose radical views forced his family to move frequently. For a time, Rev. John Ingersoll filled the pulpit for American revivalsit Charles G. Finney, while Finney was on a tour of Europe. Upon Finney's return, Reb. Ingersoll remained for a few months as co-pastor/associate pastor under Finney. The elder Ingersoll's later pastoral experiences influence young Robert negatively, however, as The Elm Telegram described in 1890.
