It seems like all our favorite nonagenarians are passing away. I have just heard about Martin Gardner’s dying at the age of 95.
I spent my youth fascinated by magic and mathematics. When i was 14 i lived in France and found that i could go to the University Library and read Martin’s legendary recreational mathematics column in Scientific American, tales of Hexaflexagons, infinite series, fractals, mathemagic and numerous other subjects that set my mind alight. He was also one of the leading figures in the skeptic movement, i would heartily recommend his books to anybody who has not yet had the pleasure of reading him. Both the mathematical writing and the essays.
James Randy posted a very nice tribute here.
