Achievements: Wozniak, or “Woz” as he's sometimes known, was Apple's co-founder and vice president of research and development from 1976 to 1985. He was the man behind the development of Apple II's hardware, software and programming language, which eventually led to the Macintosh. It was the first time that both a computer's software and hardware were developed by the same team, and in this case just one person. Wozniak's list of engineering achievements is long, beginning at age 11, but he is most well-known for his role in starting one of the most innovative companies in tech history.
Today: Since 1990, Wozniak, who has always taken an active role in education, has devoted his time to teaching Los Gatos elementary and junior-high school students about math and computers. In 2005, he co-founded Acquicor Technologies, Inc. along with two other former Apple employees as a way to acquire tech companies. Wozniak is currently the company's CTO.
