Laurene Powell Jobs, the widow of legendary Apple cofounder Steve Jobs, inherited a fortune after Jobs died in October 2011 that makes her the wealthiest woman in Silicon Valley. She maintains control of living trusts under her late husband's name, among them the Steven P. Jobs Trust, which is the largest shareholder of Walt Disney Co., with a 7.7% stake. The stake in Disney, at $6.9 billion, is worth nearly twice that of Jobs' shares in Apple. Steve Jobs met Laurene Powell in 1989 after giving a talk at Stanford University, where Powell was a student in the Graduate School of Business. Less than two years later, they were married in Yosemite. The couple had three children together. Powell Jobs, a strong advocate of education and immigration reform, sits on the boards of several nonprofits, including the NewSchools Venture Fund, Conservation International and College Track, an organization she founded that is designed to ensure admittance to and graduation from college for underserved students. She recently stepped down from her position on the board of the New America Foundation. Powell Jobs is also the founder and chair of the Emerson Collective, which works with entrepreneurs to advance education, immigration reform, social justice and conservation. In September, she was appointed to Stanford University's board of trustees. Powell Jobs was an angel investor in SocialCam, a mobile video sharing startup that was bought by Autodesk for $60 million in July. Earlier in her career, she spent several years working in investment banking and later cofounded a natural foods company in California.
