He graduated from Dartmouth College in 1861, then entered the Union Army as a private, and was promoted during the war to a captaincy. In 1865 he entered the theological seminary in Chicago, where he graduated in 1868, and preached for three years thereafter as a Congregational minister in the pulpits of Illinois. In 1871 he became a Unitarian minister, and preached for several years in various states.

He then renounced the Christianity and became an avowed freethinker. He attacked the Bible and Christianity upon the platform, and for 20 years probably making more speeches against them than any other American, speaking almost every day for months together. Putnam was married to Louise Howell for eighteen years, they divorced in 1885 due to religious differences. They had two children.

Putnam died from a gas leakage on December 11, 1896. His body was found on the floor with twenty year old lecturer May Collins in her hotel room in Boston. They had planned to go to the theatre together but were "poisoned by illuminating gas."
