Greg Graffin

On this date in 1964, Gregory Walter Graffin was born in Racine, Wis. Graffin says he was raised in "an absolute vacuum of religion." His father was a University of Wisconsin English professor. His parents divorced and he moved with his mother to Los Angeles when he was 11.

Graffin co-founded the punk rock band Bad Religion in 1980. The band released "Age of Unreason" in 2019, its 17th studio album. It was among the headliners at the 2012 Reason Rally in Washington, D.C., where Graffin sang the national anthem. He earned bachelor's and master's degrees from UCLA and a Ph.D. in zoology in 2003 from Cornell University. His thesis examined religion’s effect on humanity and included asking evolutionary biologists if they believed in God; almost 90% of those surveyed did not.

His books include Is Belief in God Good, Bad or Irrelevant? A Professor and Punk Rocker Discuss Science, Religion, Naturalism & Christianity (with Preston Jones), Evolution and Religion, Anarchy Evolution: Faith, Science, and Bad Religion in a World Without God (with Steve Olson) and Population Wars: A New Perspective on Competition and Coexistence. As of this writing he teaches a course on evolution for non-majors at Cornell between band tours. 

Graffin calls himself a naturalist and says while he doesn't believe in God, he'd rather not be called an atheist because "it's not really saying much about how you came to that conclusion." He received the Outstanding Lifetime Achievement Award in Cultural Humanism from Harvard University’s Humanist Chaplaincy in 2008.

He married Greta Maurer in 1988. After divorcing in 1996, he married Allison Kleinheinz in 2008. He has a daughter, Ella, and a son, Graham, with Greta.

“If you can believe in God, then you can believe in anything. It’s a gang mentality.”
