American Infidel: Robert G. Ingersoll
Freethought flowered in the United States in the latter half of the 19th century, and its best known advocate was Robert Green Ingersoll, a lawyer and Civil War officer, who travelled the continent for 30 years, speaking to capacity audiences. Although his repertoire included lectures on Shakespeare, Voltaire and Burns, the largest crowds turned out to hear him denounce the bible, and religion.
