Lotfi A. Zadeh is most famous for his theory of fuzzy sets. He believed that in order to fully understand a concept, it is necessary to take into account the degree to which the concept is true.

    But fuzzy logic lives on forever

    New York Times obituary source

    Lotfi Zadeh had a long and amazing life in academics and the real world. He passed away last month, aged 96.

    Today Ken and I try to convey the engineering roots of his work. Then we relate some personal stories.

    Zadeh was a Fellow of the ACM, the IEEE, the AAAI, and the AAAS and a member of the NAE. But besides this alphabet soup of US-based academies, we are impressed with the one he co-founded: the Eurasian Academy. His founding partners were a historian, a neurosurgeon, a music composer, and a mathematician. They recently elected three other members: an actress-screenwriter-director, an actor-director-writer, and a physicist.

    In any alphabet of his life, one letter stands out: the letter Z. The term “Fuzzy Set” has two of them. But Zadeh’s first widely noted work goes by just the bare letter.

    Z Is For…

    Pierre-Simon Laplace discovered a relative of the Fourier transform that has similarly motivated applications and often better behavior. When applied to the de

    The Google Doodle for November 30 featured Lotfi Zadeh.

    The Doodles page explains that

    Today’s Doodle celebrates world-renowned Azerbaijani-American computer scientist, electrical engineer, and professor, Lotfi Zadeh. On this day in 1964, Zadeh submitted “Fuzzy Sets,” a groundbreaking paper that introduced the world to his innovative mathematical framework called “fuzzy logic.”

    You can learn more about this contribution from the Wikipedia page on Fuzzy Mathematics. What I learned, from reading the Other Contributions section of Zadeh's Wikipedia page, was his role in the invention (discovery?) of the z-transform.

    In my lecture notes on the z transform, 20-odd years ago, I wrote:

    The z transform is unusual, in being named after a letter of the alphabet rather than a famous mathematician. The Fourier transform is named after Baron Jean Baptiste Joseph Fourier (1768-1830); the Walsh-Hadamard transform is named after J.L. Walsh (1895-1973) and Jacques Salomon Hadamard (1865-1963); we haven't discussed the Laplace and Hilbert transforms
