James Randi

James Randi (born Randall James Hamilton Zwinge; August 7, 1928) is a Canadian-American stage magician and scientific skeptic best known for his challenges to paranormal claims and pseudoscience. Randi is the founder of the James Randi Educational Foundation (JREF). Randi began his career as a magician named The Amazing Randi, but after retiring at age 60, he was able to devote most of his time to investigating paranormal, occult, and supernatural claims, which he collectively calls "woo-woo".

Although often referred to as a "debunker", Randi dislikes the term's connotations and prefers to describe himself as an "investigator". He has written about the paranormal, skepticism, and the history of magic. He was a frequent guest on The Tonight Show Starring Johnny Carson and was occasionally featured on the television program Penn & Teller: Bullshit!. The JREF sponsors The One Million Dollar Paranormal Challenge offering a prize of US$1,000,000 to eligible applicants who can demonstrate evidence of any paranormal, supernatural or occult power or event under test conditions agreed to by both parties.
