I suddenly recalled the circumstances under which each was written — where I was living, what I was feeling, why I was motivated to compose each tale. Those emotion-filled memories extend back more than thirty years, and yet it seems only last week that I was a graduate student in American literature at the Pennsylvania State University.The year was 1967. I was 24, about to complete my Master's degree, looking ahead to course work for my Ph.D., but unable to ignore a compulsion that had gripped me since high school: to be a fiction writer. Penn State's English Department had recently hired a noted science fiction writer, Philip Klass (whose pen name is William Tenn), to teach composition. He was the first professional writer I had met, and with the innocent brazenness of youth, I asked him if he would give me personal instruction. He answered politely that his schedule was already full to bursting and if I wanted to be his student, why not sign on for a course. I explained that I felt I would benefit more from one-on-one discussions.
