I had the pleasure of having lunch with Prof Zadeh my first year in CS right around the corner from Soda Hall. I had my book out studying and he came over and talked to me and it really made me appreciate the program. Not sure about sticks out in my head so much. I think it was just the congeniality, he made me laugh and I was stressed.

My condolences go out to his family and friends, but he made a small impact on me at least.
