Sierra is an interesting company. In the video game industry has very few well known female game designers, and that was even more true back then. Yet the adventure game genre had several - Roberta Williams, Lori Cole, Jane Jensen, and Christy Marx (not as well known, but her games are well regarded), all of whom worked for Sierra. One has to wonder if Roberta Williams being co-owner of the company (and the designer of the first graphical adventure game) is one of the reasons for this.
Another interesting story is when Ken Williams (Roberta Williams husband, the other co-owner of the company) hired middle-aged retired police officer Jim Walls to design the Police Quest adventure games (he designed the first three). Ken apparently was talking to his hairdresser about his idea for a police adventure game, when she mentioned that Walls, her husband, might be an interesting person to talk to.
