A nice NY Times article about Martin Gardner.
“…Mr. Gardner was 42 and had never taken a math course beyond high school. He had struggled with calculus and considered himself poor at solving basic mathematical puzzles, let alone creating them. But when the publisher of Scientific American asked him if there might be enough material for a monthly column on “recreational mathematics,” a term that sounded even more oxymoronic in 1956 than it does today, Mr. Gardner took a gamble.“
Martin Gardner’s 95th birthday was just over a month ago (born October 21, 1914). Dang that’s old! The article goes on to talk about his life and achievements.
