Armas Clifford "Mike" Markkula Jr. is an American electrical engineer, businessman and investor. He was an angel investor and the second CEO of Apple Computer, Inc., providing critical early funding and managerial support. Markkula was introduced to Steve Jobs and Steve Wozniak when they were looking for funding to manufacture the Apple II personal computer they had developed, after having sold some units of the first version of this computer, the Apple I. With his guidance and funding, Apple ceased to be a partnership and was incorporated as a company. Jeffrey Nordling portrayed him in the 1999 TNT film Pirates of Silicon Valley. Dermot Mulroney later portrayed him in the 2013 film Jobs.
He was lured out of retirement by Steve Jobs, who was referred to him by Regis McKenna and venture capitalistDon Valentine. Valentine—who after meeting the young, unkempt Jobs asked McKenna, "Why did you send me this renegade from the human race?"—was not interested in funding Apple, but mentioned Jobs' new company to Markkula. Jobs visited Markkula and convinced him of the market for the Apple II and for personal computers in general. In 1977, Markkula brought his business expertise along with $250,000 and became a one-third owner of Apple and employee number 3. Steve Wozniak, who designed the first two Apple computers, credits Markkula for the success of Apple more than himself. He helped the new company obtain credit and venture capital, brought in Michael Scott as the first president and CEO, then took the job himself from 1981 to 1983 despite having promised his wife that he would only stay at Apple for four years, and that he would retire by 1984. Markkula served as chairman from 1985-97, when a new board was formed after Jobs returned to the company. As chairman he approved Jef Raskin's 1979 plan to start designing what would become the Macintosh, then prevented Jobs from killing the project in favor of his own Lisa. In 1985, Markkula took John Sculley's side in a dispute with Jobs, causing the latter to leave the company; he would later help to force Sculley out in 1993. In addition to providing what The New York Times later described as "adult supervision" to the younger Jobs and Wozniak, as a trained engineer Markkula also possessed technical skills. He wrote several early Apple II programs, served as a beta tester for Apple hardware and software, and wrote one of the first three programs available for the unsuccessful Apple III. Wozniak was motivated to design the Disk IIfloppy disk drive system after Markkula found that a checkbook-balancing program he had written loaded too slowly from a data cassette. Markkula retired from Apple after Jobs returned as interim CEO in 1996. He supported Jobs' 1997 return.
