Steve Jobs was born in 1955 in San Francisco and adopted by Paul and Clara Jobs. He dropped out of college but continued auditing classes, such as one in calligraphy. In 1976, Jobs co-founded Apple Computer with Steve Wozniak and introduced the Macintosh in 1984, which was one of the first commercially successful computers with a graphical user interface. Jobs later introduced the iPod and iPhone at Apple, which became highly successful products, and transformed the company into a dominant player in the consumer electronics industry.
