  Lotfi Zadeh - Wikipedia, the free encyclopedia
Lotfi Asker Zadeh (in Persian:لطفی علی‌عسکرزاده), (born February 4, 1921) is a mathematician and computer scientist, and a professor of computer science at the University of California at Berkeley.
Lotfi Zadeh, in his theory of fuzzy logic, proposed the making of the membership function operate over the range of real numbers [0,1].
Lotfi Zadeh is also credited, along with John R. Ragazzini, in 1952, to have pioneered the development of the z-transform method in discrete time signal processing and analysis.

Zadeh believes that when one lives in the real world, one always should construct mathematical models that solve real problems rather than abstract ones.
In 1965, Zadeh had presented a paper on “fuzzy sets”; which marked the beginning of a new direction for a qualitative approach to analyse complex systems using linguistic variables deployed to describe system behaviour and performance.
In 1973, Zadeh introduced the concept of a linguistic variable and initiated a calculus of fuzzy ‘if-then’ rules, which have resulted in a huge literature on this subject.

 FAQ: Fuzzy Logic and Fuzzy Expert Systems 1/1 [Monthly posting] - [2] What is fuzzy logic?
It was introduced by Dr. Lotfi Zadeh of UC/Berkeley in the 1960's as a means to model the uncertainty of natural language.
(Note: Lotfi, not Lofti, is the correct spelling of his name.) Zadeh says that rather than regarding fuzzy theory as a single theory, we should regard the process of ``fuzzification'' as a methodology to generalize ANY specific theory from a crisp (discrete) to a continuous (fuzzy) form (see "extension principle" in [2]).

 Lotfi Zadeh Short Biography
Lotfi Zadeh, in person, is a lean, quiet, unpretentious, unassuming sort of man. He's often described as extremely gracious-a "gentleman" in the European sense of the word-even by those who don't agree with him.
Zadeh is too busy pushing forward to keep up with how far the field has expanded.
Characteristically, Zadeh is "down-to-earth", always holding abstract scientific concepts up to a reality check of their practical utility of whether they "do us any good." Since the applications of Fuzzy Logic to real life situations are infinite; it's extremely likely that we'll be hearing about Zadeh for a long, long time to come.

Those that examined Lotfi A. Zadeh's concept more closely found it to be useful for dealing with real world phenomena.
Lotfi was born in Baku in 1921 and lived there until his family moved to Tehran in 1931.
The correct spelling is LOTFI, but there are numerous instances of the F and T being reversed to LOFTI, even in books about fuzzy logic.

 Computer Science Guru to Speak at U. T. Dallas   (Site not responding. Last check: 2007-11-03)
Computing pioneer Dr. Lotfi Zadeh will discuss efforts to develop computers that perform calculations using words and perceptions rather than numbers – much like the process employed by the human brain – in an address on Friday, March 18, at The University of Texas at Dallas (UTD).
Zadeh, a computer science professor emeritus in the Graduate School of the University of California, Berkeley, who is known as the “Father of Fuzzy Logic,” will deliver a talk entitled “Precisiated Natural Language (PNL) – A Basis for a Computational Theory of Perceptions” at 11 a.m.
Like his work in the fields of fuzzy logic, soft computing and computing with words, Zadeh’s research involving PNL seeks to introduce a new paradigm in information processing, decision and control, where natural language becomes the basis of computer programming instead of the current “yes-no” architecture in which something is either true or false.
