Stephen Gary “Steve” Wozniak (born 11th August 1950), affectionately known as “Woz,” is an American electronics engineer, programmer, philanthropist, and technology entrepreneur who co-founded Apple Inc. with Steve Jobs and Ronald Wayne. As the primary designer of the Apple I and Apple II computers, Wozniak’s innovative engineering made personal computing accessible to ordinary people and launched the home computer revolution.
Early Life and Engineering Passion
Growing Up in Silicon Valley
Born in San Jose, California, Wozniak grew up during the early days of Silicon Valley when it was still primarily agricultural. His father, Jerry Wozniak, was an engineer at Lockheed who taught young Steve about electronics and the importance of precision in engineering.
Early Influences:
- Electronics fascination: Built his first computer at age 13
- Engineering ethics: Father’s emphasis on honesty and precision
- Berkeley education: Studied electrical engineering and computer science
- Prankster spirit: Famous for elaborate practical jokes and clever hacks
The Blue Box Adventure
In 1971, Wozniak and Jobs collaborated on their first commercial venture:
- Phone phreaking: Built devices to manipulate telephone systems
- Technical challenge: Wozniak enjoyed the engineering puzzle
- Business partnership: Jobs recognised the commercial potential
- Early collaboration: Established their complementary skills
This project demonstrated their partnership dynamic: Wozniak provided the technical brilliance while Jobs focused on business opportunities.
The Homebrew Computer Club
Silicon Valley’s Computer Underground
In 1975, Wozniak joined the Homebrew Computer Club, a gathering of electronics enthusiasts who shared designs and ideas:
Club Culture:
- Open sharing: Members freely exchanged technical knowledge
- Altair 8800: Intel 8080-based computer inspired many members
- DIY philosophy: Building computers was a hobby, not business
- Technical challenges: Focus on elegant engineering solutions
Designing a Better Computer
While other club members were building Altair clones, Wozniak set out to design something fundamentally different:
Design Philosophy:
- Simplicity: Fewer chips meant lower cost and higher reliability
- Integration: Built-in keyboard and video output
- Accessibility: Easy to use without extensive technical knowledge
- Affordability: Designed for mass production, not just hobbyists
The Apple I: A Revolutionary Design
Engineering Breakthrough
In 1976, Wozniak completed his design for what would become the Apple I:
Technical Innovation:
- MOS 6502 processor: Chose cheaper alternative to popular Intel and Motorola chips
