Lotfi Zadeh Wiki – Lotfi Zadeh Biography

Lotfi Zadeh was a mathematician, computer scientist, electrical engineer, artificial intelligence researcher, and professor of computer science at the University of California, Berkeley.  Zadeh is remembered for developing the innovative mathematical framework known as “fuzzy logic.”

He is being remembered with Doodle on November 30 when he submitted “Fuzzy Sets,” the groundbreaking paper that introduced the fuzzy logic concept in 1964. The concept has since been applied to several technologies, from the Japanese subway system to anti-skid algorithms that keep cars safe on the road.

Born on February 4, 1921, in Baku, Azerbaijan (part of the nascent Soviet Socialist Republic), Zadeh moved to Iran, his father’s homeland, with his family when he was 10 years old. He later graduated from the University of Tehran before continuing his education at the Massachusetts Institute of Technology for his graduate studies.

Zadeh’s fuzzy logic structure formed the basis of various modern everyday technologies, including facial recognition, air conditioning, washing machines, car transmissions, weather forecasting, stock trading, and rice cookers, UC Berkeley explains.

According to Google, Zadeh’s famed paper became one the most cited papers in the history of the information sciences, having been cited by scholars nearly 100,000 times to date.

More than 33,000 patents and applications with “fuzzy” in the title are listed in the U.S. patent database, with tens of thousands of fielded applications, ranging from camera-focusing systems to automated-train controls and other industrial technologies.


Lotfi Zadeh was married to his wife Fay Zadeh, and the couple had two children, Stella and Norman Zada. His wife wrote a book, My Life and Travels with the Father of Fuzzy Logic, about their travels and experiences together, visiting “exotic places” and meeting interesting people worldwide.


Zadeh died in his home in Berkeley, California, on September 6, 2017, at the age of 96. His cause of death was not revealed at the time. He is buried in the first Alley of Honor in Baku, Azerbaijan, where he was born. His funeral was well attended by “highly respected people,” including the President of Azerbaijan, Ilham Aliyev. A month before his death, the University of Tehran had released an erroneous report that Zadeh had died but withdrew it several days later.
