Stephen Gary "Woz" Wozniak (born August 11, 1950 in San Jose,
California) is an American computer engineer, and the co-founder of
Apple Computer (now Apple Inc.), with Steve Jobs. His inventions
and machines are credited with contributing greatly to the personal
computer revolution of the 1970s. Wozniak created the Apple I and
Apple II computers in the mid-1970s. The Apple II gained a sizable
amount of popularity, eventually becoming one of the best selling
personal computers of the 1970s and early 1980s.
Wozniak has several nicknames, including "The Woz", "Wonderful
Wizard of Woz" and "iWoz" (a reference to the ubiquitous naming
scheme for Apple products). "WoZ" (short for "Wheels of Zeus") is
also the name of a company Wozniak founded. He is known for his
introverted character, and he finds his level of celebrity somewhat
annoying. He is also known as the "Other Steve" of Apple Computer,
the better known Steve being co-founder and current CEO Steve Jobs.
He and his family are of Polish descent.

Together with Steve Jobs, Steve Wozniak created the first commercially available personal computers and helped establish home computing for the masses. The two men went on to found Apple Computers, Inc.
