Don't forget his LZEXE from the good old DOS days which was an excellent piece of work at the time.

I remember LZEXE from those olden days. When I discovered the author of FFmpeg and QEMU also created LZEXE, I was so impressed. I've been using his software for my entire computing career.

It's similar to the respect I have for the work of Anders Hejlsberg, who created Turbo Pascal, with which I learned to program; and also C# and TypeScript.

Self-decompressing executables felt like magic to me at the time. Fantastic work, overall.
