Michael Shermer, American historian, author, and academic, founded The Skeptics Society
Michael Brant Shermer (born September 8, 1954) is an American science writer, historian of science, executive director of The Skeptics Society, and founding publisher of Skeptic magazine, a publication focused on investigating pseudoscientific and supernatural claims. The author of over a dozen books, Shermer is known for engaging in debates on pseudoscience and religion in which he emphasizes scientific skepticism.

Shermer was the co-producer and co-host of Exploring the Unknown, a 13-hour Fox Family television series broadcast in 1999. From April 2001 to January 2019, he contributed a monthly Skeptic column to Scientific American magazine.

Once a fundamentalist Christian, Shermer ceased to believe in the existence of God during graduate school. He accepts the labels agnostic, nontheist, atheist but prefers to be called a skeptic. He also describes himself as an advocate for humanist philosophy as well as the science of morality.
