Philip Roth’s loving tribute to a teacher is available via Audible. He discusses the process with the Paris Review:

Philip Roth Reads “In Memory of a Friend, Teacher and Mentor”:

In those days we had a lot of good teachers. There were a couple of bad ones—boring. But by and large they were inspiring. Bob and I were talking about the time I was in high school. He said, You kids made us good.
