Celebrity Skeptic, Magician (Canada)
James Randi is a Canadian-American retired stage magician and scientific skeptic who has extensively challenged paranormal and pseudoscientific claims. Randi is the co-founder of Committee for Skeptical Inquiry (CSI) and the founder of the James Randi Educational Foundation (JREF). He began his career as a magician under the stage name The Amazing Randi and later chose to devote most of his time to investigating paranormal, occult, and supernatural claims, which he collectively calls "woo-woo". Randi retired from practicing magic aged 60, and from the JREF aged 87.
Although often referred to as a "debunker", Randi has said he dislikes the term's connotations and prefers to describe himself as an "investigator". He has written about the paranormal phenomena, 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!
Prior to Randi's retirement, JREF sponsored the One Million Dollar Paranormal Challenge, which offered a prize of US$1,000,000 to eligible applicants who could demonstrate evidence of any paranormal, supernatural or occult power or event under test conditions agreed to by both parties. The paranormal challenge was officially terminated by the JREF in 2015. The foundation continues to make grants to non-profit groups that encourage critical thinking and a fact-based world view.
He has received the Richard Dawkins Award and the American Humanist Association Lifetime Achievement Award, among many others, and holds two Guinness World Records.
