If Steve Wozniak had "only" designed the Apple II, one of the foundational computers of the early PC era, he'd still be a computing legend. But after leaving Apple in the mid-'80s Wozniak went on to help establish the Electronic Frontier Foundation, sponsored the Children's Discovery Museum of San Jose, and has spent the last four decades on philanthropy, public speaking and founding a truly wild range of tech companies, like one focused on minimizing orbital debris.
What makes him one of the all-time greats though, at least in my mind, is that despite decades in the tech business and access to fabulous wealth he by all accounts seems to have remained an almost absurdly chill and normal guy.
