Sheryl
Sandberg

She is the operator whose face shareholders recognized before the founder’s. The closest thing tech has produced to a household-name COO. A two-word book title that became a wing of the language, and the cover photo that launched a thousand internal pitch decks at companies she had never set foot in.

Arc

She came up through Treasury under Larry Summers, then Google in 2001, where she built the global online sales operation. Mark Zuckerberg hired her in March 2008 to turn Facebook from a campus product into a business. She did, year after year, until the company was Meta and the revenue line ran flush against the ceiling. *Lean In* arrived in 2013 and became the most-discussed business book of the decade. *Option B* followed in 2017, written after the sudden death of her husband. She left the COO chair in August 2022 and the Meta board in May 2024. The book, the org, and the operator are three separate legacies on one résumé.

Why she’s in the library

Not a face the algorithm reads as cinema. A face the public read for fifteen years as the steady second seat at the most-discussed company on the planet. Round-frame glasses, blonde bob, the controlled half-smile that held across every earnings cycle. The public face of a generation of female tech leadership. An anchor for that index point.
