stamps_az,

I wasn't aware a stamp had been issued for Zadeh. I had the opportunity to study some of his work when I took a course on Fuzzy Sets and Systems in graduate school. It was one of the more fun courses I took for my MS degree. Second only to a course in General Systems Theory.

Thanks for sharing.
