Sheryl Kara Sandberg was born on August 28, 1969, in Washington, D.C., and grew up in Aventura, Florida, the eldest of three children of Joel Sandberg, an ophthalmologist, and Adele Sandberg, a French language teacher. She attended North Miami Beach High School and Harvard College, where she majored in economics and graduated summa cum laude in 1991 — working with Lawrence Summers as her thesis advisor. She attended Harvard Business School, receiving her MBA in 1995, and joined McKinsey & Company briefly before returning to Washington to work as chief of staff for Treasury Secretary Lawrence Summers during the Clinton administration. She moved to Silicon Valley in 2001, joining Google as vice president of global online sales and operations, where she built the advertising operations that became Google's primary revenue engine.
Sheryl Sandberg joined Facebook as Chief Operating Officer in March 2008, recruited by Mark Zuckerberg after he identified her at a Christmas party as someone with the operational experience the company needed to scale. She brought to Facebook the advertising infrastructure knowledge she had developed at Google, transforming the platform from an advertising afterthought into one of the most profitable advertising businesses in history. By 2012, she had become the first woman elected to Facebook's board of directors, and by 2016, Forbes ranked her among the most powerful women in the world. Her partnership with Zuckerberg — he the visionary technical founder, she the operational executive who built the business infrastructure — was one of the most consequential leadership partnerships in Silicon Valley history.
Sheryl Sandberg's 2013 book Lean In: Women, Work, and the Will to Lead was the most discussed book on women in business of the decade, selling more than 5 million copies worldwide and launching the Lean In Foundation, which supports women's leadership development globally through tens of thousands of Lean In Circles. The book's central argument — that women should assert themselves more boldly in professional contexts, lean into their careers rather than pulling back in anticipation of future family demands — generated genuine cultural debate: praised for naming and addressing real patterns of self-limitation, criticized for placing the burden of gender equity change on individual women rather than on the structural conditions that constrain them. The debate itself — the fact that a business book generated genuine feminist controversy — was itself evidence of Sandberg's cultural reach.
In May 2015, Sandberg's husband Dave Goldberg, the CEO of SurveyMonkey, died suddenly of cardiac arrhythmia while exercising in Mexico during a family vacation. The loss — sudden, complete, leaving her a widowed mother of two young children — produced the most personal experience of her public life, and she processed it partly through a subsequent book, Option B: Facing Adversity, Building Resilience, and Finding Joy (2017), co-written with resilience researcher Adam Grant. The book was received as both a personal grief narrative and a practical framework for resilience, and the Option B Foundation she established has continued work in this area. She stepped down as Facebook's COO in June 2022, citing a desire to focus on her philanthropic work and her marriage to entrepreneur Tom Bernthal. Her tenure at Facebook — which concluded amid significant controversy about the platform's role in political disinformation — remains the most consequential corporate career of any woman in Silicon Valley history.
