John D. Rockefeller

Rockefeller surfaces across two books as an archetype of the great capitalist. In Buffett — The Biography, he heads the closing comparison of history’s great capitalists — Rockefeller “the oil cartelist,” Andrew Carnegie “the philanthropic steel baron,” Sam Walton “the humble retailer,” and Bill Gates “the software nerd” — all of whom owe their fortunes to a single product or innovation. The point is a foil for Warren Buffett, who is set apart because he made his money as a pure investor picking diverse businesses and stocks rather than building one dominant enterprise.

In The Psychology of Money, Rockefeller appears twice. He is the case study for how thin the line is between “genius” and “criminal”: Morgan Housel asks how little the narrative would have to shift to turn “Rockefeller was a genius, try to learn from his successes” into “Rockefeller was a criminal, try to learn from his business failures.” He also appears as a model of disciplined silence — a recluse who “lets everybody else talk, while he sits back and says nothing,” reciting the wise-old-owl poem about how the less he spoke, the more he heard.

Context: John D. Rockefeller (1839–1937) founded Standard Oil, building it into a near-monopoly over American oil refining; he became history’s first known dollar billionaire and later one of its most consequential philanthropists.

Where this appears

• Buffett — The Biography — heads the lineup of single-product great capitalists, used as a foil for Buffett the pure investor
• The Psychology of Money — case study in the thin genius/criminal narrative line, and a model of disciplined silence

From “Things To Internet”

• “Robber barons” — the 19th-century pejorative for Gilded Age industrialists and financiers accused of building fortunes through monopoly and ruthless practice; Rockefeller and Standard Oil are the standard example. Saved to Kyle’s Apple Note “Things To Internet” (c. 2013–2015), as the bare term “Robber Barons”.
