Abstract :
A multitude of outspoken critics disputed the theory of fuzzy logic, developed by Lotfi A. Zadeh in the mid-1960s. Some 20 years were to pass before the theory became widely accepted-capped by the 1995 award of the IEEE Medal of Honor to Zadeh “for pioneering development of fuzzy logic and its many diverse applications”. Even today some critics remain. But Zadeh never wavered. He had found himself alone in his scientific opinions on several earlier occasions. This paper describes how the inventor of fuzzy logic persisted despite decades of opposition
