I think Kyle's explanation is wrong. Russel is the first who told about the paradox of modeling some real world problems by classical set theory. Later, Black expanded it to explain vagueness, but not explicitely fuzzy logic. It is of course obvious that Zadeh did not invent this theory on some magical day, he saw and used the accumulated knowledge about the vagueness and he recognized the need of a different kind of model for the vagueness. (Please refer to Zhang, l., (1993) Structural and functional quantization of vagueness, Fuzzy Sets and Systems, vol. 55, p. 51-60; Wallsten,T.S., "Measuring vague uncertainties and understanging their use in decision making", dans Acting under uncertainty : multidisciplinary conceptions, 1990, p. 377-398 G.M.

Fuzzy Logic was created by Max Black in the 1930's. In his paper
"Vagueness, an exercise in logical analysis" he cites Bertrand Russel,
Albert Einstein and even Plato a basis for his ideas. See "Philosophy of
Science" (1937) Vol. 4 pp. 427-455.
