The History section of the IBM website has interesting pages with nice pictures. There is of course a John Backus page. Anecdotally, I learned that there is a 6830 Johnbackus (1991 JB1) asteroid between Mars and Jupiter. If you have read the original post of the thread Anecdotal Fortran, you already know there is a 9548 Fortran asteroid. Fortran is definitely one of the rare languages with such an honor.
