OK, jumping on the history train here...
My lisp journey started in a CS class at UC Berkeley taught by Professor Richard Fateman (of Macsyma and Maxima fame). I volunteered on the first day to fix the lisp system (nil wasn't evaluating to nil, but generating an error). It was Harvard Lisp and it ran on a PDP 11 I think. It was written in assembler and had comments about class assignments. Fateman hired me after that class and I worked for him on Franz Lisp. First task was to port Liszt (the compiler) from the VAX to the Motorola 68000. The machine was in a closet and was bigger than a fridge. We got an early Sun workstation and I ported to that, too. 4MB of RAM was the same as the VAXen we had.
I helped found Franz, Inc (with 4 others) in 1984 and have been here ever since. I manage the Lisp group, do release management for Allegro CL, as well as lots of other things.
