Steve Wozniak
Stephen Gary Wozniak, also known by his nickname Woz, is an American technology entrepreneur, electrical engineer, computer programmer, and inventor. In 1976, he co-founded Apple Computer with his early business partner Steve Jobs. Through his work at Apple in the 1970s and 1980s, he is widely recognized as one of the most prominent pioneers of the personal computer revolution.
In 1975, Wozniak started developing the Apple I into the computer that launched Apple when he and Jobs first began marketing it the following year. He was the primary designer of the Apple II, introduced in 1977, known as one of the first highly successful mass-produced microcomputers, while Jobs oversaw the development of its foam-molded plastic case and early Apple employee Rod Holt developed its switching power supply.
With human–computer interface expert Jef Raskin, Wozniak had a major influence over the initial development of the original Macintosh concepts from 1979 to 1981, when Jobs took over the project following Wozniak's brief departure from the company due to a traumatic airplane accident. After permanently leaving Apple in 1985, Wozniak founded CL 9 and created the first programmable universal remote, released in 1987. He then pursued several other business and philanthropic ventures throughout his career, focusing largely on technology in K–12 schools, which involved a 1990 initiative to place computers in schools in the former Soviet Union.
He has received numerous awards and honors for his work in philanthropy and the tech industry, including an induction into the National Inventors Hall of Fame in 2000. As of June 2024, Wozniak has remained an employee of Apple in a ceremonial capacity since stepping down in 1985. In recent years, he has helped fund multiple entrepreneurial efforts dealing in areas such as GPS and telecommunications, flash memory, technology and pop culture conventions, technical education, ecology, satellites and more. In addition to his American citizenship, Wozniak is also a Polish and Serbian citizen.
Early life
Stephen Gary Wozniak was born on August 11, 1950, in San Jose, California. His mother, Margaret Louise Wozniak , was from Washington state, and his father, Francis Jacob "Jerry" Wozniak of Michigan, was an engineer for the Lockheed Corporation. Wozniak graduated from Homestead High School in 1968, in Cupertino, California. Steve has one brother, Mark, a former tech executive who lives in Menlo Park. He also has one sister, Leslie, who attended Homestead High School in Cupertino. She is a grant adviser at Five Bridges Foundation, which helps at-risk youths in San Francisco. Leslie said it was her mother who introduced activism to her and her siblings.The name on Wozniak's birth certificate is "Stephan Gary Wozniak", but his mother said that she intended it to be spelled "Stephen", which is what he uses. Wozniak is of Polish and German ancestry. In the early 1970s, Wozniak's blue box design earned him the nickname "Berkeley Blue" in the phreaking community. Wozniak has credited watching Star Trek and attending Star Trek conventions while in his youth as a source of inspiration for his starting Apple Computer. In his autobiography, iWoz, he also credits the Tom Swift Jr. books as an inspiration for becoming an engineer.
Career
Pre-Apple
In 1969, Wozniak returned to the San Francisco Bay Area after being expelled from the University of Colorado Boulder in his first year for hacking the university's computer system. He re-enrolled at De Anza College in Cupertino before transferring to the University of California, Berkeley, in 1971. In June of that year, for a self-taught engineering project, Wozniak designed and built his first computer with his friend Bill Fernandez.Predating useful microprocessors, screens, and keyboards, and using punch cards and only 20 TTL chips donated by an acquaintance, they named it "Cream Soda" after their favorite beverage. A newspaper reporter stepped on the power supply cable and blew up the computer, but it served Wozniak as "a good prelude to my thinking 5 years later with the Apple I and Apple II computers". Before focusing his attention on Apple, he was employed at Hewlett-Packard, where he designed calculators. It was during this time that he dropped out of Berkeley and befriended Steve Jobs.
Wozniak was introduced to Jobs by Fernandez, who attended Homestead High School with Jobs in 1971. Jobs and Wozniak became friends when Jobs worked for the summer at HP, where Wozniak, too, was employed, working on a mainframe computer.

Their first business partnership began later that year when Wozniak read an article titled "Secrets of the Little Blue Box" from the October 1971 issue of Esquire, and started to build his own "blue boxes" that enabled one to make long-distance phone calls at no cost. Jobs, who handled the sales of the blue boxes, managed to sell some two hundred of them for $150 each, and split the profit with Wozniak. Jobs later told his biographer that if it had not been for Wozniak's blue boxes, "there wouldn't have been an Apple."
In 1973, Jobs was working for arcade game company Atari, Inc. in Los Gatos, California. He was assigned to create a circuit board for the arcade video game Breakout. According to Atari co-founder Nolan Bushnell, Atari offered $100 for each chip that was eliminated in the machine. Jobs had little knowledge of circuit board design and made a deal with Wozniak to split the fee evenly between them if Wozniak could minimize the number of chips. Wozniak reduced the number of chips by 50, by using RAM for the brick representation. Whilst a lack of scoring or coin mechanisms made Woz's prototype unusable, Jobs was paid the full bonus regardless. Jobs told Wozniak that Atari gave them only $700 and that Wozniak's share was thus $350. Wozniak did not learn about the actual $5,000 bonus until ten years later. While dismayed, he said that if Jobs had told him about it and had said he needed the money, Wozniak would have given it to him.
In 1975, Wozniak began designing and developing the computer that would eventually make him famous, the Apple I. With the Apple I, Wozniak was largely working to impress other members of the Palo Alto–based Homebrew Computer Club, a local group of electronics hobbyists interested in computing. The club was one of several key centers which established the home hobbyist era, essentially creating the microcomputer industry over the next few decades. Unlike other custom Homebrew designs, the Apple had an easy-to-achieve video capability that drew a crowd when it was unveiled.
Zaltair
Wozniak also created the fictional computer Zaltair. Adam Schoolsky and Randy Wigginton helped him to pull it off at the West Coast Computer Conference. It was a parody of the Altair 8800 computer, which was very popular at the time. Steve Wozniak thought of the name because:The company Zilog had come out with a compatible processor, which they called the Z-80. A few companies using this chip were establishing brands based on Z words. Like ComputerZ or Z-Node or the like.As a joke, Wozniak decided to print "20,000 brochures" of a fake product called the 'Zaltair' with a lot of "superlative descriptions of a computer that solved every problem in the world". It advertised, among other things, a new version of the BASIC programming language called "BAZIC", with the ability to "define your own language... a feature we call perZonality".
To help make the ad believable, he included fake trademarks and a shipping label for MITS, the company manufacturing the Altair. Wozniak did not think that this would be an issue, as he had "made sure in advance that MITS would not be at the show." However, it later turned out that a representative from MITS was attending, and had been taking large amounts of their fake brochures. He also made sure the article had a fake quote from Ed Roberts, then president of MITS, which spelled out the name of a rival company, Processor Technology, when looking at the first letter of every word, further ensuring that the article was not traced back to him.
Steve Jobs, Wozniak's close friend at the time, received a copy of the brochure. He fell for it, and even "took pride that the Apple II stacked up well against the Zaltair in the comparison chart". However, he, like many others, did not realize Wozniak had created the brochure until "Woz gave him a framed copy of the brochure as a birthday gift" in 1985.
Apple formation and success
By March 1, 1976, Wozniak completed the basic design of the Apple I computer. He alone designed the hardware, circuit board designs, and operating system for the computer. Wozniak originally offered the design to HP while working there, but was denied by the company on five occasions. Jobs then advised Wozniak to start a business of their own to build and sell bare printed circuit boards of the Apple I. Wozniak, at first skeptical, was later convinced by Jobs that even if they were not successful they could at least say to their grandchildren that they had had their own company. To raise the money they needed to build the first batch of the circuit boards, Wozniak sold his HP scientific calculator while Jobs sold his Volkswagen van.On April 1, 1976, Jobs and Wozniak formed the Apple Computer Company along with administrative supervisor Ronald Wayne, whose participation in the new venture was short-lived. The two decided on the name "Apple" shortly after Jobs returned from Oregon and told Wozniak about his time spent on an apple orchard there.
After the company was formed, Jobs and Wozniak made one last trip to the Homebrew Computer Club to give a presentation of the fully assembled version of the Apple I. Paul Terrell, who was starting a new computer shop in Mountain View, California, called the Byte Shop, saw the presentation and was impressed by the machine. Terrell told Jobs that he would order 50 units of the Apple I and pay $500 each on delivery, but only if they came fully assembled, as he was not interested in buying bare printed circuit boards.
Together the duo assembled the first boards in Jobs's parents' Los Altos home; initially in his bedroom and later in the garage. Wozniak's apartment in San Jose was filled with monitors, electronic devices, and computer games that he had developed. The Apple I sold for $666.66. Wozniak later said he had no idea about the relation between the number and the mark of the beast, and that he came up with the price because he liked "repeating digits". They sold their first 50 system boards to Terrell later that year.
In November 1976, Jobs and Wozniak received substantial funding from a then-semi-retired Intel product marketing manager and engineer named Mike Markkula. At the request of Markkula, Wozniak resigned from his job at HP and became the vice president in charge of research and development at Apple. Wozniak's Apple I was similar to the Altair 8800, the first commercially available microcomputer, except the Apple I had no provision for internal expansion cards. With expansion cards, the Altair could attach to a computer terminal and be programmed in BASIC. In contrast, the Apple I was a hobbyist machine. Wozniak's design included a $25 CPU on a single circuit board with 256 bytes of ROM, 4K or 8K bytes of RAM, and a 40-character by 24-row display controller. Apple's first computer lacked a case, power supply, keyboard, and displayall components that had to be provided by the user. Eventually about 200 Apple I computers were produced in total.

After the success of the Apple I, Wozniak designed the Apple II, the first personal computer with the ability to display color graphics, and BASIC programming language built in. Inspired by "the technique Atari used to simulate colors on its first arcade games", Wozniak found a way of putting colors into the NTSC system by using a chip, while colors in the PAL system are achieved by "accident" when a dot occurs on a line, and he says that to this day he has no idea how it works. During the design stage, Jobs argued that the Apple II should have two expansion slots, while Wozniak wanted eight. After a heated argument, during which Wozniak threatened that Jobs should "go get himself another computer", they decided to go with eight slots. Jobs and Wozniak introduced the Apple II at the April 1977 West Coast Computer Faire. Wozniak's first article about the Apple II was in Byte magazine in May 1977. It became one of the first highly successful mass-produced personal computers in the world. Wozniak also designed the Disk II floppy disk drive, released in 1978 specifically for use with the Apple II to replace the slower cassette tape storage.
In 1980, Apple went public to instant and significant financial profitability, making Jobs and Wozniak both millionaires. The Apple II's intended successor, the Apple III, released the same year, was a commercial failure and was discontinued in 1984. According to Wozniak, the Apple III "had 100 percent hardware failures", and that the primary reason for these failures was that the system was designed by Apple's marketing department, unlike Apple's previous engineering-driven projects.
During the early design and development phase of the original Macintosh, Wozniak had a heavy influence over the project along with Jef Raskin, who conceived the computer. Later named the "Macintosh 128k", it would become the first mass-market personal computer featuring an integral graphical user interface and mouse. The Macintosh would also go on to introduce the desktop publishing industry with the addition of the Apple LaserWriter, the first laser printer to feature vector graphics. In a 2013 interview, Wozniak said that in 1981, "Steve really took over the project when I had a plane crash and wasn't there."
