Stephen Gary Wozniak (born on August 11, 1950), also nicknamed "The Woz", is an American inventor, electronics engineer, programmer, philanthropist, and technology entrepreneur who co-founded Apple Inc. He is known as a pioneer of the personal computer revolution of the 1970s and 1980s, along with Apple co-founder Steve Jobs.
Wozniak single-handedly developed the 1976 Apple I, which was the computer that launched Apple. He primarily designed the 1977 Apple II, known as one of the first highly successful mass-produced microcomputers, while Jobs oversaw the development of its unusual case and Rod Holt developed the unique power supply. After stepping away from Apple in 1985, Wozniak founded CL 9 and created the first universal remote. He then became involved in several other business and philanthropic ventures, focusing primarily on tech in K–12 schools. Wozniak is currently Chief Scientist at the data virtualization company, Primary Data, and remains an employee of Apple in a ceremonial capacity.
