Thomas W. Flynn (August 18, 1955 – August 23, 2021) was an American author, journalist, novelist, executive director of the Council for Secular Humanism, and editor of its journal Free Inquiry. He was also director of the Robert Green Ingersoll Birthplace Museum and the Freethought Trail. Much of Flynn's work addressed church-state issues, including his 1993 book The Trouble with Christmas, in connection with which he made hundreds of radio and TV appearances in his role as the curmudgeonly "anti-Claus", calling attention to what he viewed as unfair treatment of the nonreligious during the year-end holiday season. He edited The New Encyclopedia of Unbelief, a comprehensive reference work on the history, beliefs, and thinking of men and women who live without religion. He contributed a new Introduction to A History of the Warfare of Science with Theology in Christendom by Andrew Dickson White and blogged on The Washington Post'''s On Faith site during 2010 and 2011. He blogged regularly on the Center for Inquiry's blog Free Thinking. He was also the author of several anti-religious, black comedy, science fiction novels. Early life In an autobiographical chapter in Flynn's 1993 The Trouble with Christmas, Flynn stated that he was born in 1955 in Erie, Pennsylvania, the only child of a moderately conservative Catholic family. He believed zealously in the teachings of the pre-Vatican II Roman Catholic Church, beginning to question its teachings only after many church doctrines and practices were revised in the wake of the Second Vatican Council, which affected parish life when Flynn was a young adolescent. He earned his bachelor's degree at Xavier University, the Jesuit university in Cincinnati, Ohio, where the school's emphasis on philosophy and theology gave him the tools he needed to pursue his religious questions at a more serious level. Over several years of inquiry he rejected his Catholicism, then his Christianity, and ultimately his theism. Acknowledging that he had become an atheist in 1980 while residing in Milwaukee, Wisconsin, he visited Milwaukee's downtown library, looked up "atheism" in the card catalogue, and found the so-called Dresden Edition of The Works of Robert G. Ingersoll on the open stacks. Reading Ingersoll's florid Gilded Age speeches in defense of agnosticism and atheism confirmed him in his identity as an atheist and kindled his desire to become a public activist for unbelief.
