Stephen Gary Wozniak, known familiarly as Woz, is an American electrical engineer, computer programmer, inventor, and technology entrepreneur who co-founded Apple Computer with Steve Jobs in 1976. A self-taught electronics prodigy who grew up in California's Santa Clara Valley, Wozniak designed and hand-built the Apple I and Apple II computers — machines that helped launch the personal computer revolution of the late 1970s and early 1980s. His engineering work on the Apple II, which became one of the first mass-produced microcomputers, established the technical foundation upon which Apple grew into one of the world's most consequential technology companies. After departing Apple in 1985, Wozniak pursued a range of entrepreneurial and philanthropic ventures, including founding CL 9, which produced the first programmable universal remote control. He has devoted significant energy to technology education, particularly in K–12 schools, and has been recognized with numerous honors including induction into the National Inventors Hall of Fame in 2000. Reflecting on Apple's origins ahead of the company's 50th anniversary in 2026, Wozniak remarked, "Steve Jobs wanted a company and he did it," crediting Jobs's business ambition as the catalyst that transformed their shared technical interests into a corporate enterprise. As of 2024, Wozniak has remained a nominal employee of Apple in a ceremonial capacity.

Early Life

Stephen Gary Wozniak was born on August 11, 1950, in San Jose, California. He grew up in the Santa Clara Valley, an area that would later become known as Silicon Valley. His father, Francis Jacob "Jerry" Wozniak, was an engineer at Lockheed Martin, and his influence played a formative role in the young Wozniak's interest in electronics.

From an early age, Wozniak displayed a pronounced aptitude for electronics and engineering. He developed an intense fascination with how electronic circuits worked and spent much of his youth designing and building his own projects. His engineering interests extended to computers at a time when computing was largely confined to universities and large corporations. As a teenager, Wozniak was already designing computer circuits on paper, working through the logic of how processors and memory systems could be organized to perform useful tasks.

It was during the early 1970s that Wozniak's path first crossed with that of Steve Jobs, a younger student who shared his enthusiasm for electronics and technology. The two were introduced through a mutual friend, and their friendship would prove transformative for both men and for the computing industry at large. In 1971, the pair began collaborating on various projects, marking the beginning of an origin story that would ultimately lead to the founding of Apple Computer. CBS News has described Wozniak during this period as an "engineering prodigy" and Jobs as a "computer enthusiast," a characterization that captures the complementary dynamic that would define their partnership.

One notable early collaboration between Wozniak and Jobs involved the creation of "blue boxes" — devices that could generate tones to manipulate the telephone network, allowing users to make free long-distance calls. While illegal, the project demonstrated Wozniak's technical skill and the pair's ability to work together toward a shared engineering goal.

Education

Wozniak attended the University of Colorado Boulder before ultimately transferring and earning his degree from the University of California, Berkeley. At Berkeley, he completed degrees in electrical engineering and computer science. However, Wozniak's formal education was interrupted by his involvement in hands-on engineering projects, and he did not complete his degree until after he had already co-founded Apple and achieved significant success in the technology industry. His return to Berkeley to finish his studies reflected his personal commitment to completing his education despite having already demonstrated his engineering abilities in the commercial arena.

Career

Early Work and the Founding of Apple

Before founding Apple, Wozniak worked at Hewlett-Packard, where he was employed as a calculator engineer. During this period, he continued to pursue personal computing projects in his spare time, attending meetings of the Homebrew Computer Club, a gathering of electronics hobbyists in the San Francisco Bay Area that proved instrumental in the development of the personal computer industry.

In 1975, Wozniak began developing what would become the Apple I computer. He designed the machine's hardware largely on his own, driven by a desire to create a personal computer that individuals could own and operate. When Steve Jobs saw the commercial potential of Wozniak's creation, he proposed that they form a company to sell it. On April 1, 1976, Wozniak and Jobs, along with Ronald Wayne, officially founded Apple Computer. Wayne sold his share back to Jobs and Wozniak shortly afterward.

The Apple I was sold as a circuit board without a case, keyboard, or monitor, and was aimed primarily at hobbyists. Nonetheless, it represented a significant step in making computing accessible to individuals outside of institutional settings. According to Wozniak, Jobs was the driving force behind the decision to turn their technical work into a business. In a 2026 interview reflecting on Apple's 50th anniversary, Wozniak stated: "Steve Jobs wanted a company and he did it."

The Apple II

Wozniak's most significant engineering achievement at Apple was the design of the Apple II, which was introduced in 1977. The Apple II represented a major advance over the Apple I, incorporating a number of features that made it accessible and appealing to a far broader audience. Wozniak served as the primary designer of the computer's hardware and software, while Jobs oversaw the development of its external design, including its distinctive foam-molded plastic case. Early Apple employee Rod Holt developed the machine's switching power supply, another important technical contribution.

The Apple II is recognized as one of the first mass-produced microcomputers to achieve broad commercial success. Its open architecture, color graphics capability, and expandability via internal slots made it attractive not only to hobbyists but also to businesses and educational institutions. The inclusion of a built-in BASIC programming language interpreter, written in part by Wozniak, allowed users to begin programming immediately upon turning on the machine.

The commercial success of the Apple II transformed Apple from a garage startup into a major corporation and generated significant wealth for both Wozniak and Jobs. The machine remained in production in various iterations for over a decade and sold millions of units worldwide. Ars Technica has cited the Apple II era as a critical period in the history of personal computing, during which Apple established a significant share of the emerging market.

Work on the Macintosh and the 1981 Airplane Accident

Following the success of the Apple II, Wozniak became involved in the early development of the Macintosh project. Working alongside human–computer interface expert Jef Raskin, Wozniak contributed to the initial concepts for the original Macintosh between 1979 and 1981. This work explored ideas about making computers even more intuitive and accessible to non-technical users, themes that would define the Macintosh when it was eventually released.

In February 1981, Wozniak was involved in a traumatic airplane accident when the Beechcraft Bonanza he was piloting crashed during takeoff. The accident resulted in significant injuries, including temporary amnesia. Wozniak took a leave of absence from Apple to recover, during which time Jobs assumed control of the Macintosh project and steered it in a new direction.

Wozniak returned to Apple after his recovery but found that the company had changed significantly during his absence. He eventually resumed engineering work but increasingly felt disconnected from the company's direction.

Departure from Apple

Wozniak permanently left his active role at Apple in 1985, though he has maintained a ceremonial employee status with the company from that point onward. In a letter published on his personal website, Wozniak confirmed that he "never left Apple" in a formal sense, retaining his employee badge and receiving a nominal salary. This arrangement has continued for decades; as of June 2024, Wozniak remained on Apple's payroll in this honorary capacity.

Reflecting on his departure and Apple's trajectory, Wozniak has been candid about the differing roles he and Jobs played. In interviews surrounding Apple's 50th anniversary in 2026, Wozniak emphasized that while he and Jobs did not foresee the vast technological future that would unfold, they "took the first step" toward global computing for ordinary people.

CL 9 and the Universal Remote

After leaving Apple, Wozniak founded CL 9, a company focused on consumer electronics. In 1987, CL 9 released the first programmable universal remote control, a device that allowed users to consolidate control of multiple home entertainment components into a single handheld unit. While the product did not achieve the same level of commercial success as the Apple II, it represented an innovative contribution to consumer electronics and demonstrated Wozniak's continued interest in making technology more user-friendly.

Later Ventures and Public Speaking

In the decades following his departure from Apple, Wozniak pursued a wide range of business and philanthropic activities. He helped fund and support multiple entrepreneurial efforts in fields including GPS and telecommunications, flash memory, technology and pop culture conventions, technical education, ecology, and satellite technology.

Wozniak became a prominent figure on the public speaking circuit, frequently appearing at technology conferences, universities, and corporate events to discuss innovation, education, and the history of personal computing. In December 2025, Lehigh University announced that Wozniak would participate in its Compelling Perspectives Series to provide a "tech-informed perspective on the future of AI."

In 2026, as Apple marked its 50th anniversary, Wozniak participated in multiple media interviews and reflections on the company's origins. He appeared in a CBS News special alongside Apple CEO Tim Cook, with both men reflecting on their experiences with Steve Jobs and the company's early history. In a Parade magazine feature, Wozniak and Cook discussed special moments with Jobs and the personal qualities that drove Apple's early culture.

Wozniak also reflected on Apple's early days in connection with a new book release, discussing how the company's origins were rooted in a culture of experimentation and hands-on engineering rather than grand strategic planning.

A 2025 profile by Farnam Street noted that after Apple's initial success, Wozniak made the unusual decision — by Silicon Valley standards — to give millions of dollars of his own money away, a choice that reflected his personal values regarding wealth and community responsibility.

Personal Life

Wozniak has been married three times. His first marriage was to Alice Robertson in 1976; the couple divorced in 1980. He married Candice Clark in 1981, and they divorced in 1987. His third marriage was to Suzanne Mulkern in 1990; they divorced in 2004. He has three children.

In addition to his American citizenship, Wozniak holds Polish and Serbian citizenship. His Polish heritage traces back to his father's ancestry, and he has publicly acknowledged his connection to Polish culture.

Wozniak has spoken openly about the personal impact of his 1981 airplane accident, which caused temporary amnesia and required a significant recovery period. The experience altered his perspective on life and contributed to his decision to step back from intensive corporate work at Apple and pursue a wider range of personal and philanthropic interests.

Throughout his post-Apple career, Wozniak has been involved in philanthropy focused on technology education. In 1990, he helped lead an initiative to place computers in schools in the former Soviet Union, reflecting his belief in the importance of providing young people with access to computing technology regardless of geopolitical boundaries.

Wozniak has also expressed interest in the impact of emerging technologies on society. In his 2025 appearance at Lehigh University, he addressed the future of artificial intelligence, a topic he has discussed publicly on multiple occasions.

Recognition

Wozniak has received numerous awards and honors for his contributions to technology and philanthropy. In 1985, he was awarded the National Medal of Technology by President Ronald Reagan, alongside Steve Jobs, recognizing their work in developing the personal computer.

In 2000, Wozniak was inducted into the National Inventors Hall of Fame, an honor that placed him among the most significant inventors in American history.

Wozniak has received honorary degrees from multiple universities and has been the subject of numerous biographical accounts, documentaries, and dramatizations. His role in the founding of Apple has made him one of the most recognized figures in the history of the technology industry.

The Motley Fool profiled Wozniak in 2000, examining his post-Apple career and his contributions to the broader technology ecosystem.

In media appearances, Wozniak has been interviewed by major outlets including CNN and The New York Times. A 2009 New York Times article discussed his continued involvement in technology and public life. CNN has featured him in multiple segments discussing both his Apple legacy and his views on contemporary technology trends.

Legacy

Steve Wozniak's engineering work on the Apple I and Apple II placed him at the center of the personal computer revolution. His designs demonstrated that computing could be made accessible to individuals rather than remaining the exclusive domain of institutions and corporations. The Apple II, in particular, established a template for what a personal computer could be — affordable, expandable, and usable by people without specialized technical training.

Wozniak's legacy extends beyond his specific engineering contributions. His partnership with Steve Jobs became one of the defining collaborations in the history of technology, pairing Wozniak's deep engineering talent with Jobs's commercial instincts and design sensibility. The dynamic between the two men has been studied and referenced in business and technology contexts for decades.

In a 2016 interview with The Conversation, Wozniak was described as a co-founder of Apple and "inventor of the home computer," a characterization that, while simplified, speaks to the magnitude of his impact on the industry.

Wozniak's philanthropic focus on technology education, particularly his efforts to bring computers into K–12 schools and his 1990 initiative in the former Soviet Union, reflected a consistent belief that technology's value lies in its ability to empower individuals. His decision to give away significant portions of his personal wealth, noted in a 2025 Farnam Street profile, distinguished him from many of his contemporaries in Silicon Valley.

As Apple celebrated its 50th anniversary in 2026, Wozniak's foundational role continued to be acknowledged by the company and the broader technology community. His observation that Apple "didn't foresee the future, but took the first step" captured both the modesty and the significance of the work that he and Jobs began in the mid-1970s.
