MOVING TO FRONT from August 12: see Updates.
I have just learned from colleagues in Austin that Professor Frede has died. He taught at Berkeley, Princeton, and, since 1991, at Oxford. He was one of the preeminent scholars of ancient philosophy in our time. On a personal note, I can report that he was a kind and inspiring undergraduate teacher, whom I was fortunate to have for classes on Aristotle and Plato. I will post links to memorial notices as they appear.
UPDATE: A memorial notice from the Berkeley Classics Department is here.
ANOTHER: Andreas Schmidhauser has prepared a bilbiography of Professor Frede's work. I must say it is a bit perturbing that it's three weeks since Professor Frede's tragic and untimely death, and there still appear to have been no substantial obituaries in the media. Perhaps I have missed them. Please feel free to post pertinent links in the comments.
UPDATE OCTOBER 21: An English-language obituary at last! (Thanks to Ophelia Benson for the pointer.)
