In fact, the roots of fuzzy logic go back much further than that,
including
most importantly the work of Lukasiewicz in the 1930s. Lukasiewicz
actually proposed min-max logic very early on; Zadeh's papers give
several references to his work. A brief discussion of the history can
be found in Klir and Yuan (1995), pp. 217 ff.
