How Ideas of L.A. Zadeh Gave Rise to Mathematical Fuzzy Logic

Everybody who heard Zadeh’s plenary talks in various conferences could realize that Lotfi never gave the same talk twice, despite the fact that he was giving each year about 60 lectures all over the world. And even when repeating something, he always explained the matter from different points of view or shed a different light on it. His talks are never too detailed, but they are always full of inspiration, suggesting new ideas, new concepts. Though one cannot always agree with his way of solution of the given problem, his suggestions and ideas sooner or later found fertile soil and made us think about our problems from a new perspective. His work, personality, way of life, permanent good and positive mood are never ending source of inspiration for which we are grateful to him.
