Robert Green Ingersoll (August 11, 1833–July 21, 1899) was an American lawyer, writer, lecturer, and political figure born in Dresden, New York. He became one of the leading voices of the Golden Age of Free Thought and was widely known for defending agnosticism and challenging religious orthodoxy.

A Civil War colonel and former Illinois attorney general, Ingersoll built his greatest reputation as a public speaker. His lectures combined humor, eloquence, and strong arguments for reason, freedom of conscience, equality, and human progress, making him one of the most famous American orators of the nineteenth century.
