**Early life and Family**

**Lofti Zadeh** was born in Baku, Azerbaijan SSR, as **Lotfi Aliasker zadeh.** His father was **Rahim Aleskerzade, a**n Iranian Muslim Azerbaijani journalist from Ardabil who was on assignment from Iran, and his mother was **Fanya Korenman,** she was a Jewish pediatrician from Odessa, Ukraine, who was an Iranian citizen.

The Soviet government at that time courted foreign correspondents, and the family lived well while in Baku. Zadeh went to elementary school for three years there, which he said* “had a relevant and long-lasting influence on my thinking and my way of looking at things.”*

In 1931, when Stalain started agricultural cultivation, and Lofti Zadeh was ten, his father moved his family back to Tehran, Iran.

Lofti Zadeh was registered in Alborz High School, a missionary school, where he was educated for the about eight years, and met his wife, named Fay Faina Zadeh, who said that he was “highly influenced” by the “high level of decency, beauty, honest and helpful” Presbyterian missionaries from the United States who handled the college. “To me they stand for the best that one would find in the United States people from the Midwest with great roots.

They were actually ‘Good Samaritans’ with the zeal to sacrifice themselves for the good of others. So this type of character influenced me greatly says Lofti Zadeh. This made him have a strong desire to live in the United States. At this time, Zadeh was given several awards.

Lofti Zadeh sat for the Iran national university examination and came third in the nation. As a student, he came first in his class in his first two years.

In 1942, he completed his college education from the University of Tehran with a degree in electrical engineering, he was one of only three students in that field to graduate that year, due to the chaos caused by World War II, when the United States, Britain and the Soviet Union overrun Iran.

Over 30,000 American soldiers were based there, and Lofti Zadeh worked with his father, who did business with them as a contractor for hardware and building materials.

**Lofti Zadeh Education and Career**

Lofti Zadeh in 1943 made a decision to further his education in the United States. He travelled to Philadelphia through Cairo after he was delayed for months while he waited first for the accurate papers and thereafter for the right ship to arrive. Lofti got there in mid-1944, he lived in New York City and was an employee for an electronic association.

He went into the Massachusetts Institute of Technology (MIT) and graduated in September that year. Lofti shortened his family name, while he was in the United States. He formed a new middle name from the part of the name he removed, he was later referred to as Lotfi Aliasker Zadeh.

Also, He received an Master degree in electrical engineering from MIT in 1946.

In 1947, Zadeh started working at Columbia University since his parents had settled in New York. Then he applied to Columbia University, the university admitted him as a doctoral student and he was offered an instructorship as well.

Lofti got his Ph.D. in electrical engineering from Columbia in 1949 and he became an assistant professor the following year.

Lofti Zadeh lectured for ten years at Columbia University and was promoted and became a full fleshed professor in 1957.

The chairman of the electronic engineering department at the University of California, wrote to him and he was offered a job. In 1959, Lofti Zadeh joined the Electrical Engineering faculty at the University of California, Berkeley.

At the time of his long research career, Lofti Zadeh made a crucial scientific contributions in two clear dimension, which are “linear system theory and classical control systems”, and “Fuzzy sets, fuzzy logic, and other related science and technology.

Lofti Zadeh was given an award of the Guggenheim Fellowship in 1967 for Natural Sciences in Applied Mathematics.

Lofti Zadeh’s first essential research contribution, was well known among scholars of his generation in the electrical engineering community, which was in the aspect of classical control systems. His pioneer work, co-authored with Charles Desoer, Linear System Theory: The State Space Approach, formed an extremely important foundation for all contemporary approaches to system analysis and control.The second and most popular contribution of Lofti’s research is his whole life dedication to the establishmy, enhancement and the real-world influence of a wide collection of science and technology basically on fuzzy sets and fuzzy logic.

Lofti published his seminal work on fuzzy sets in 1965, where he explained the motivation of replicating human-like reasoning and he gave complete explaination and full information about the mathematics of fuzzy set theory.

Lofti proposed his theory of fuzzy logic in 1973. Both, fuzzy sets and fuzzy logic gives the important basis for a wide class of related innovations, which includes but is not restricted to:

-Fuzzy database : Generalizes classical database query language using fuzzy sets and fuzzy logic

-Neuro-fuzzy systems :A synergistic combination of fuzzy logic and neural networks, providing the first interpretable AI system based on neural network learning

-Fuzzy control :A practical approach to non-linear control using fuzzy if then rules in fuzzy logic

-Fuzzy pattern recognition: A generalization of conventional pattern recognition techniques using fuzzy sets (e.g., fuzzy k-means generalizes k-means clustering)

-Fuzzy mathematics: Generalizes conventional mathematics using fuzzy sets and fuzzy logic

Lofti was also among the Board of Governors for International Neural Network Society (INNIS) in 2003.

**Lofti Zadeh** was also a Fellow of the Institute of Electrical and Electronics Engineers, Association for the Advancement of Artificial Intelligence, the Association for Computing Machinery, the American Academy of Arts and Sciences, and the International Fuzzy Systems Association, and a member of the National Academy of Engineering.

He was also a member of the Academies of Science of Azerbaijan, Korea, Finland, Poland and Bulgaria and of the International Academy of Systems Studies in Moscow. Lofti got 24 honorary doctorates.

**Lofti Zadeh’s Personal life**

**Lofti Zadeh** got married to **Fay Zadeh** and had two children, Stella Zadeh and Norman Zada. Zadeh’s wife, Fay Zadeh, wrote about her travels and their experiences they had together in visiting** “exotic places”** and meeting lovely people around the world in her book titled “My Life and Travels with the Father of Fuzzy Logic”.

**Who is Lofti Zadeh’s wife?**

**Lotfi Zadeh** met his wife in Tehran. They were lovers for very long time, they started dating from their basic school called Alborz College. His wife is already dead, she died in 2005.

Fay Zadeh was an established writer and author. She wrote about her travels and experiences in visiting exotic places together with her husband.

One of her books is titled ‘My Life and Travels with the Father of Fuzzy Logic’.
