Yesterday's Readercon post, for instance, included a passing remark about Isaac Asimov at Bread Loaf, and I just now took the source of this information out of a box: Whose Woods These Are: A History of the Bread Loaf Writers' Conference, 1926-1992 by David Haward Baine and Mary Smyth Duffy, which I bought when I attended Bread Loaf in the summer of 2000.
Asimov first visited Bread Loaf in 1950 at the invitation of one of the faculty members, Fletcher Pratt. In 1971 and 1972, he attended as a member of the faculty, invited by his friend John Ciardi, who was director of the conference for many years.
My favorite of the anecdotes about Asimov in the book comes from Seymour Epstein:
I remember [Asimov] saying something to the effect that I must teach him how to create fully dimensioned characters, and my thinking that I would be happy to try it if he would teach me how to make even a fraction of what he made on his writing.
