In addition to Algol-W and Pascal. Niklaus Wirth also
developed Modula-2 and
Oberon.
Oberon is particularly interesting because it included a language, an
operating system, and a computer. There aren’t that many folks who could
build a complete environmnet from scratch.
He also devised an HDL before switching to Verilog. (The original
Oberon UI influenced Pike's acme, though Pike thought Wirth was too
minimalist.)
At any rate, this page has a picture of Auld Nick (as some wags called
him) in his lab with board and helicopters:
