Back in 1968, IBM's CEO fired Lynn Conway for being trans. She was a computer science pioneer at the company. Today, they apologized for it. Hard to believe this shit is still going on today.
Conway ended up five years later at Xerox PARC and, later still, DARPA.
As impressive a life as she's had in computers, equally as impressive is her trans activism. Give her Wikipedia a read.
TLDR? Her inventions power the device you're reading this on.
