Parapsychology texts contain many references to Czechoslovakian clairvoyant Pavel Stepanek. Stepanek's tested "ESP" success rate of over 60% caused the 1970 edition of the "Guinness Book of World Records to proclaim him "the best clairvoyant ever tested". Science writer Martin Gardner disagrees.
Martin Gardner, the creator of Scientific American's "Mathematical Games" column, which he wrote for more than twenty-five years, is the author of almost one hundred books, including The Annotated Ancient Mariner, Martin Gardner's Favorite Poetic Parodies, From the Wandering Jew to William F. Buckley Jr., and Science: Good, Bad and Bogus. For many years he was also a contributing editor to the Skeptical Inquirer.
