Sometimes called, "the father of Fuzzy Logic"
Dealing with mathematically assessing things with inexact or inadequate
quantification

One of my profs (William Cooper) had a discussion with him about the
mathematical combination of multiple inexact items. After Zadeh talked
about mathematically combining the uncertainties, Cooper asked, "Isn't
that just probability?"
Zadeh responded, "probably".
He came up with ways to work with inexact items. He never claimed to be
"FIRST" at anything.
