Professor Lotfi A. Zadeh, Father of Fuzzy Logic, Associate Editor in WSEAS Transactions on Systems
We are deeply saddened to share the sad news that Professor Lotfi A. Zadeh passed away on Sept. 6, 2017 at the age of 97.
Prof. Zadeh has been Associate Editor in WSEAS Transactions on Systems as well as Honorary Editor in several WSEAS Books
His vision has guided us to build the Cognitive Informatics and Cognitive Computing Community and related research in the last 16 years.
Prof. Zadeh was a giant scientist of the world.
His seminal work in logic, fuzzy mathematics, and soft computing, etc., have and will influence many generations of researchers and students. We will remember his pioneer contributions to knowledge forever.
He was best known for proposing the fuzzy mathematics consisting of those fuzzy-related concepts:
fuzzy sets, fuzzy logic, fuzzy algorithms, fuzzy semantics, fuzzy languages, fuzzy control, fuzzy systems, fuzzy probabilities, fuzzy events, and fuzzy information.
Rest in peace, dear Professor Zadeh

Prof. Michio Sugeno, Associate Editor in WSEAS Transactions on Systems and Control and Plenary Speaker in the 1st WSEAS International Conference on Fuzzy Sets and Fuzzy Systems (FSFS '01), Puerto De La Cruz, Canary Islands, Spain, February 11-15, 2001

Prof. Michio Sugeno (Professor Emeritus, Tokyo Institute of Technology), 83, passed away on Wednesday, 9 August 2023, after a short battle with a brain tumor. Dr. Michio Sugeno, known to all of you, has left many milestones in the field of fuzzy theory and applications that I do not need to mention. His profound contributions, ranging from fuzzy measure/Sugeno integral to fuzzy control and computing with words, have had a lasting influence on generations of researchers. Prof. Michio Sugeno was Associate Editor in our Journal "WSEAS Transactions on Systems and Control" for more than 10 years. He had been also Plenary Speaker in our 1st WSEAS International Conference on Fuzzy Sets and Fuzzy Systems (FSFS '01), Puerto De La Cruz, Canary Islands, Spain, February 11-13, 2001. His audience as Plenary Speaker in Puerto De La Cruz, Spain in February of 2001 was about 300 Scholars.
Prof. Michio Sugeno received the B.Sc. degree from the Department of Physics, University of Tokyo, Tokyo, Japan, in 1962. He was with the company for three years and then with the Tokyo Institute of Technology, Tokyo, Japan, as a Research Associate, an Associate Professor, and a Professor from 1965 to 2000. After retiring from the Tokyo Institute of Technology, he was a Laboratory Head with the Brain Science Institute, RIKEN, from 2000 to 2005 and then as a Distinguished Visiting Professor with the Doshisha University from 2005 to 2010. Finally, he was an Emeritus Researcher with the European Centre for Soft Computing, Spain, from 2010 to 2015.
Prof. Dr. Michio Sugeno was the President of the Japan Society for Fuzzy Theory and Systems from 1991 to 1993, and also the President of the International Fuzzy Systems Association from 1997 to 1999. He is the first recipient of the IEEE CIS Pioneer Award in Fuzzy Systems with Zadeh in 2000. He was the recipient of the 2010 IEEE Frank Rosenblatt Award. He was also the recipient of the IEEE International Conference on Systems, Man, and Cybernetics 2017 Lotfi A. Zadeh Pioneer Award. Thus, he achieved many theoretical and technical accomplishments and led the fuzzy community as a distinguished pioneer through his excellent studies. As one of his former Ph.D. students, I was fortunate to learn about his belief and passion for research through his thought-provoking advice. His contribution and leadership to the fuzzy community have been invaluable and we will miss our great leader very much.
