Mocked at its birth, fuzzy logic outlived its critics to become one of the most cited and most applied ideas in science. Its author was honoured on three continents.
Citation totals grow over time and are quoted as of 2021. Honorary-doctorate counts vary by source (24–26); Berkeley gives 25.

“For pioneering development of fuzzy logic and its many diverse applications.”

ICT category — “for the invention and development of fuzzy logic.” (Presented 2013.)
For federally funded basic research with a vast practical payoff.
He was a member of the U.S. National Academy of Engineering and foreign academies in Azerbaijan, Bulgaria, Finland, Korea and Poland, and a Fellow of IEEE, ACM, AAAS and AAAI. In 2014 the IEEE created the “Lotfi A. Zadeh Pioneer Award.”
The boy from Baku came home. Beyond the burial in the Alley of Honour, Azerbaijan has woven his name into its scientific life — a centenary postage stamp (2021), a Baku street, an honorary membership of the National Academy, “Lotfi Zadeh” scholarships at ADA University and a national olympiad in his name. On 30 November 2021 a Google Doodle carried his stylised face worldwide.

Over his grave the bronze arms stay open — and the formula stays carved in the stone.
