Maybe, but not the first. And definitely not the "father of computer sciences"
He was not “FOUNDER of computer sciences” rather.
I think he would be better called the father of modern computational theory. But given that pretty much the entire industry calls him the father of computer sciences, it’s probably an apt moniker. And that came out before the whole gay movement, so it’s about his contributions, not about the gays hijacking his professional reputation for their own ends.
I think you like to look at the person rather than the accomplishments. An American officer doesn’t denounce Rommel because he was a Nazi, he recognizes Rommel as a brilliant tactician.
