Jobs was ethnically Arab from his father, who belongs to a prominent family of Syrian Arab origin. His mother was of Swiss-German and German descent.
Steven Jobs was born on February 24, 1955. He was adopted shortly thereafter by a California couple, Paul and Clara Jobs.
Steve Jobs's biological parents were Abdulfattah Jandali and Joanne Schieble. His parents were unmarried students. Joanne studied in the magistracy of the University of Wisconsin, and Jandali also worked as an assistant teacher. As Joan's relatives objected to their relationship, and her father, who was at death, threatened to deprive her of his inheritance, she had to leave to a private doctor in San Francisco, and then she gave the child for adoption.
Stephen's adoptive parents could not have their own children. They named the adoptive son Stephen Paul. Joan wanted Stephen's adoptive parents to have a higher education, and when she found out that Clara did not graduate from college and Paul studied only in high school, she signed adoption papers only after they had made a written commitment to pay for Stephen's college education.
When Jobs was two, he was joined by an adopted sister, Patricia. Seeking more space for their growing family, the Job's family moved to Mountain View, California in 1961. In a bigger house, Paul Jobs returned to his hobby of rebuilding cars, constructing a workbench for his son. Young Steve jobs would help his father rebuild cars as well as with a wide range of household building and repair projects. These projects would serve as a background for Jobs’ early interest in electronics, one he shared with the many engineers who lived in his new neighborhood.
Jobs always thought of Paul and Clara as a father and mother, he was very annoyed if someone called them adoptive parents: "They are my real parents by 100%". According to the rules of formal adoption, biological parents didn't have any information about their son's location, and Steve met with his own mother and younger sister only 31 years later.
