Ed was (with Wes Salmon) the humblest and kindest faculty member in the Department of History and Philosophy of Science in the years I studied there (1965-69). He and Wes paid attention to the circumstances of students, and helped where they could. Ed helped me a lot. When he went on sabbatical to Europe (or somewhere) and took his family, he offered me his family car to use while he was away. I was surprised, since the offer came out of the blue, and Iaccepted. Ed must have learned that I had sold my family's car to feed the three of us. (Graduate stipends were barely adequate for one person, and in those days there was no safety net.) I felt very bad when he returned and I gave him back his car, no longer capable of moving in reverse. I am glad he died peacefully. He was a splendid man.
