In light of the movie that's coming out I feel a correction is needed. Joe Hyland did not create Jem,, contrary to what is on this website. He and his wife were involved in the business end but the creative aspect was done by Bill Sanders. There's a backstory there but not really relevant anymore. I've also discovered on various websites (not least of which is Wikipedia) that Christy Marx is being credited with creating Jem. This is very distressing to the few of us left from Bill's family.
