Gardner inspired and, according to Raymond Carver, sometimes intimidated his students. At Chico State College (where he taught from 1959 to 1962), when Carver mentioned to Gardner that he had not liked the assigned short story, Robert Penn Warren's "Blackberry Winter," Gardner said, "You'd better read it again." "And he wasn't joking", said Carver, who related this anecdote in his foreword to Gardner's book "On Becoming a Novelist". In that foreword, he makes it clear how much he respected Gardner and also relates his kindness as a writing mentor.
