There's room to split hairs over the first cartridge based console, or the first console with interchangeable games. But no matter what, the Channel F was designed by Mr. Lawson from first principles.
Mrs. Williams' pet project series remains one of my favorite duologies in gaming - Laura Bow. If you say that she was the cofounder, you also have to point out that Ken & Roberta were a married couple, so no matter what she'd have been involved. It's more about what she contributed to gaming and her skill with crafting coherent stories both AGI and SCI - and you can see that in KQ4, since it was released in both AGI and SCI!
I have to admit that I never got into the BioWare D&D games - my preference remained with Black Isle's development (Planescape: Torment); but I respect others like them more than me.
The first person to put together principles on programming was a woman (Ada Lovelace). One of the most influential programming languages in the world, and the origin of the term 'computer bug', come from a woman (Captain Grace "Amazing Grace" Hopper). Women programmed the computers that put men on the moon and got them home safely. Dr. Ellis, a black man, was the first black person to get a Computer Science PhD, and (arguably) created the first known GUI.
These are all good people who made our lives better.
