Was listening to the excellent podcast series about computing in 1968, called "1968: When the World Began" by Nextbillionseconds which Paul shared not so long ago. I was pretty sure I had never heard about Mark Pesce until I got to episode 4 in the series, and Mark shares that he's a co-inventor of VRML (https://en.wikipedia.org/wiki/VRML).

Last time I came across VRML was in 2003 while working on my masters degree, where I used it to visualise scenes from an interactive film. I had never heard about VRML before back then, and I never heard about it since. Took me by surprise, I was not expecting to ever hear about it again either (:

Fantastic podcast series btw, 4 great episodes, highly recommend it (https://nextbillionseconds.com/2018/11/23/1968-when-the-world-began-part-one-the-pivot/)
