Raised on welfare in a single-parent household in Oakland, California, the daughter of a Chinese immigrant, Shanahan went from a successful career as a patent lawyer and entrepreneur to marrying into uber-wealth after meeting Google co-founder Sergey Brin at a yoga festival. The two divorced in 2022, amid reports that she had had an affair with Brin’s friend and fellow tech titan, Elon Musk. (Shanahan and Musk deny the allegations.)

Like so many others who have amassed a fortune from the tech sector, Shanahan has become a philanthropic force but also a political player.
