Steven Jobs was born February 24, 1955, in San Francisco, California, and was adopted by Paul and Clara Jobs. He grew up with one sister, Patty. Paul Jobs was a machinist and fixed cars as a hobby. Jobs remembers his father as being very skilled at working with his hands.

In 1961 the family moved to Mountain View, California. This area, just south of Palo Alto, California, was becoming a center for electronics. Electronics form the basic elements of devices such as radios, televisions, stereos, and computers. At that time people started to refer to the area as "Silicon Valley." This is because a substance called silicon is used in the manufacturing of electronic parts.

As a child, Jobs preferred doing things by himself. He swam competitively, but was not interested in team sports or other group activities. He showed an early interest in electronics and gadgetry. He spent a lot of time working in the garage workshop of a neighbor who worked at Hewlett-Packard, an electronics manufacturer.
