Lotfi Zadeh Centenary Celebration

The IEEE Computational Intelligence Society (IEEE CIS) and the International Fuzzy Systems Association (IFSA) have decided to jointly celebrate the centenary of Lotfi A. Zadeh (1921-2017), to pay tribute to the creator of fuzzy set theory, an active member of both our societies.

We are pleased to give voice to those who knew him and appreciated him around the world to remind us what a scientist and what a man he was. A few videos prepared by some of his old friends will be posted on the page below. Many thanks to all those who provided photos from their collections to participate in this commemoration.

They will tell us about some of the moments spent with him. If you met Lotfi Zadeh, you are welcome to write short testimonials about his achievements and his personality and to upload photos with him in our Collabratec Community.
