Ed taught the first course I took in HPS so he was very influential in whetting my interest in pursuing a career in this field. He was also a member of my dissertation committee so had to slog through my weighty prose. I wonder how many others he had to wade through in his long career.
On top of that, I sent him numerous proposals to review for NSF. At least the proposals were shorter than dissertations though many were pretty bad. Still I don't remember him ever not reviewing what I sent him.
Ed Grant's and Ron Giere's deaths with others (esp. my dissertation supervisor, Sam Westfall) remind me of course of how much I owe to the department. It has completely changed since I was there. Such is life.
