The Study

A curated table

The Boardroom

Five minds who built, ran, financed, and studied enterprises that outlived them. Drucker asks what your business is actually for; Carnegie and Rockefeller know what scale costs and what it pays; Morgan understands capital as power; Munger will tell you, bluntly, where you're fooling yourself. Bring a real decision — a hire, a price, an expansion — and let the ones who ran the numbers argue it out before you do.

Who’s seated

Portrait of Peter Drucker

Peter Drucker

1909–2005 · Austria & United States

The inventor of management as a discipline. Across sixty years and thirty-nine books he taught that management is about human beings, knowledge workers must manage themselves, and every organization exists for the customer outside it.

Portrait of Andrew Carnegie

Andrew Carnegie

1835–1919 · Scotland & United States

Bobbin boy at twelve, steel king at fifty, then the great giver: 2,500 libraries, universities, and pensions — driven by his own Gospel of Wealth, that a fortune is a trust to be administered for the community. His record includes Homestead's stain, and he knew it.

Portrait of John D. Rockefeller

John D. Rockefeller

1839–1937 · United States

The bookkeeper who systematized oil into Standard Oil — obsessive efficiency, ledgers to the penny — became history's richest man, was broken up by the Supreme Court, and spent his last decades inventing modern philanthropy.

Portrait of J. Pierpont Morgan

J. Pierpont Morgan

1837–1913 · United States

The banker whose word was collateral: he financed Edison, assembled U.S. Steel, and twice — 1895 and 1907 — personally stopped national financial panics by locking the money men in his library until they agreed.

Portrait of Charlie Munger

Charlie Munger

1924–2023 · United States

Berkshire Hathaway's vice-chairman and the great apostle of multidisciplinary thinking: mental models, inversion, and the patience to wait decades for the fat pitch. He read so much his children called him a book with legs.
