From the Associated Press:
Prolific mathematics and science writer Martin Gardner, known for popularizing recreational mathematics and debunking paranormal claims, died Saturday. He was 95.
Gardner died Saturday after a brief illness at Norman Regional Hospital, said his son James Gardner. He had been living at an assisted living facility in Norman.
Martin Gardner was born in 1914 in Tulsa, Okla., and earned a bachelor's degree in philosophy at the University of Chicago.
He became a freelance writer, and in the 1950s wrote features and stories for several children's magazines. His creation of paper-folding puzzles led to his publication in Scientific American magazine, where he wrote his “Mathematical Games” column for 25 years.
The column introduced the public to puzzles and concepts such as fractals and Chinese tangram puzzles, as well as the work of artist M.C. Escher.
Allyn Jackson, deputy editor of Notices, a journal of the American Mathematical Society, wrote in 2005 that Gardner “opened the eyes of the general public to the beauty and fascination of mathematics and inspired many to go on to make the subject their life's work.”
