Witold Kosiński (August 13, 1946 in Kraków – March 14, 2014 in Warsaw) was a Polish mathematician and computer scientist. He was the lead inventor and main propagator of Ordered Fuzzy Numbers (now named after him: Kosiński's Fuzzy Numbers).

For many years Professor Witold Kosiński was associated with the Institute of Fundamental Technological Research of the Polish Academy of Sciences. He has also worked as the Vice-Chancellor of the Polish-Japanese Institute of Information Technology - PJIIT (now called Polish-Japanese Academy of Information Technology) in Warsaw and the Head of the Artificial Systems Division at the PJIIT. Finally, he was a lecturer at the Faculty of Mathematics, Physics and Technical Sciences, the Kazimierz Wielki University in Bydgoszcz.

Professor Kosiński was a researcher specialising in continuum mechanics, thermodynamics, and wave propagation as well as in mathematical foundations of information technology and particularly in artificial intelligence, fuzzy logic and evolutionary algorithms. His fields of research have also comprised applied mathematics and partial differential equations of hyperbolic type as well as neural networks and computational intelligence.

He was a scientist, mentor to scientific staff and several generations of students, as well as an active athlete. Provided by Wikipedia
