The founder of fuzzy logic Lotfi Zafeh and his precursor, Max Black wee
born in Baku. What a coincidence!

In my search on the ideas that lead to fuzzy logic, I saw a reference by
Jan Dejnozka about the following persons to be relevant to the history
of fuzzy logic:
Bertrand Russel, Jan Lukasiewicz, Max Black, James McCauley, Lotfi
Zadeh.
He refers to his book (unfortunately it is unclear to which one -
unfortunately I have no access to any of them).

The relevant references seem to be the following:

1. Bertrand Russel, "Vagueness", in the Australian Journal of
Philosophy, 1, 1923.
(by the way, not mentioned by Klir&Yuan).

2. Max Black, "Vagueness, an exercise in logical analysis", Philosophy
of Science, 4(4), 1937, pp. 427-455 (reprinted in Intern. J. of General
Systems, 17(2-3), 1990, pp. 107-128.

3. For Lukasiewicz there are some references to a spech in 1918, but
somewhere else there was note indicating that his first paper was in
1917.

It seems that the first paper of Zadeh using the notion of fuzziness is
not

Lotfi Zadeh, "Fuzzy sets", Information and Control, 8(1965), pp.338-353
,

but

Lotfi Zadeh, "From circuit theory to system theory", Proceedings of the
Institute of Radio
Engineers 50, 1962), pp. 856-865.

But who is McCauley? (may be McCawley?)

Any answers/clarifications to the previous questions would be
appreciated
