James Randi (born Randall James Hamilton Zwinge; August 7, 1928 – October 20, 2020) was a Canadian-American stage magician and scientific skeptic who extensively challenged paranormal and pseudoscientific claims. He was the co-founder of the Committee for Skeptical Inquiry (CSI), and founder of the James Randi Educational Foundation (JREF). Randi 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 called "woo-woo". Randi retired from practicing magic at age 60, and from his foundation at 87.
