Robert (Bob) Dennard, inventor of the DRAM and Dennard scaling, died on April 23, 2024. I never met Bob, but heard many stories from his IBM colleagues who said he was universally loved and admired. The comment that sticks with me from several people who worked with him: every time you saw Bob Dennard he always had a smile on his face.
