History of programming languages

These proceedings of the ACM SIGPLAN History of Programming Languages (HOPL) conference are a record, in the words of those who helped make the history, of a baker's dozen of the languages that set the tone of most of today's programming. It is difficult to describe the feeling that prevailed at the conference. There were no parallel sessions. Some attendees were graduate students, some pioneers, many were practitioners, and there seemed roughly an even division between industrial and academic affiliation. It was the first conference I attended where virtually everyone attended every session.
