I recently acquired several volumes in the Time-Life series "Understanding Computers". The volume "Computer Languages" discusses the history of most of the widely used languages and the following comments are based on material in that book. I think that this particular book may be a useful source of historical and anecdotal material for the individual that posted the original request for information (sorry, I don't have that message any more). FORTRAN was developed by an IBM team led by John Backus. It appears that developing the compiler took much more time then was ever anticipated and was six months to completion for two years. Backus regards the major contribuiton of FORTRAN as the organization of loops. The first release of FORTRAN was in April 1957 and the book refers to the attempts (succesful) by Herb Bright at the Westinghouse-Bettis Atomic Power Lab to run the compiler blind (it was recieved with no instructions). It is not clear if they were the very first outside IBM to use the new compiler but they were one of the first. FORTRAN II followed only about a year after the original release. This version allowed for, among other things, links to assembly language. FORTRAN III was written in 1958 and FORTRAN IV was announced in 1962. I hope the above information is useful. For further information the Time Life book cited above has an extensive bibliography that cites many book and journal articles that would be interesting reading. The journal "Annals of the history of computing" is cited frequently and the following issues may be particularly interesting: October 1982 and July 1979. The latter includes an article by Backus "The History of FORTRAN I, II and III". I have not read any of these articles; our library does not subscribe to this journal.
