Penn Jillette is a well-known American magician, actor, television presenter, and author. He became interested in magic early in his life and began his career as a street performer soon after graduating from Ringling Brothers and Barnum & Bailey Clown College. His career took a positive turn when at the age of nineteen he met Raymond Joseph Teller. Although they came from a different background, they soon formed a close bond and began holding shows initially with Weir Chriseme; and later without him. Known simply as ‘Penn & Teller’, the duo has been featured in numerous stage and television shows, including Penn & Teller: Bullshit! and Penn & Teller: Fool Us. A firm believer in atheism, he became an atheist while in school and is currently known for his advocacy of atheism and scientific skeptism. Also an established author, his book, God, No!: Signs You May Already Be an Atheist and Other Magical Tales, was a New York Times Best Seller.
