Joseph Traub, Who Helped Bring Computer Science to Universities, Dies at 83

I took a class with Prof. Traub, he would explain a problem, ask us to come up with an algorithm and then always ask "Can we do better?" and push us to find a better solution, he repeated it so often that every time I think about solving something "Can we do better?" is at the back of my mind.

He was interested in optimal algorithms and was one of the founders of the field of "information-based complexity": https://en.wikipedia.org/wiki/Information-based_complexity

Never had the chance to meet him, but I still have a lot of respect for what he's done for Computer Science. Thank you Joseph, and may you rest in peace.
