The NYT asks and answers this question in a charming obituary for Martin Gardner, who died on the 22nd of this month at age 95.
I enjoyed his puzzles when I was a kid and his Annotated Alice is a lot of fun.
Don't you hate it when you read an obituary for someone when you didn't realize they were still alive?
How embarrassing.
