💹The Greats

Rothschild really did learn of Wellington's victory at Waterloo about a day before the British government, via his courier network, and really did inform the Treasury. The legend that he crashed the market with false rumors and bought Britain cheap traces not to 1815 but to an 1846 French pamphlet, and historians have dismantled it. His documented masterstroke was logistics: assembling and smuggling gold through blockaded Europe to pay Wellington's army in 1814–15 — a contract that made the firm's fortune and reputation at once.

On the night of 2 November 1907, with trust companies failing across New York and no central bank in existence, the 70-year-old Morgan gathered the city's leading bankers in his private library on East 36th Street, locked the doors, and pocketed the key. By 4:45 a.m. they had committed $25 million to save the tottering trust companies, and the panic broke. Congress drew the obvious conclusion — that no private citizen should ever again hold that role — and created the Federal Reserve six years later.

In January 1907, with Osaka's exchange still euphoric from the post-Russo-Japanese-War boom, Nomura took a heavily short position — not on instinct but on weeks of his own price analysis and news reading, a discipline then almost unknown among Japanese brokers. The crash that followed made his fortune and vindicated the research desk he had established at the family shop the year before. The firm he built on that principle grew into Nomura, Japan's largest investment bank, which in 2008 bought Lehman Brothers' Asian and European operations.

In the winter of 1958–59, nearly the whole City establishment lined up behind British Aluminium's board to block a bid by Tube Investments and America's Reynolds Metals. Warburg, advising the bidders, ignored the club convention that hostile approaches were simply not done and went over the directors' heads to shareholders, buying stock in the open market. He won in January 1959, was socially frozen out, and within a decade every firm that had shunned him was imitating the "Aluminium War" playbook he wrote.

Benham built her authority in railroad bonds — the blue-chip securities of the era — while concealing the one fact that would have discredited her with clients: she signed her research "I. H. Benham," so that railroad executives corresponding with the Street's sharpest rail analyst assumed for years they were writing to a man. The 1964 Pressprich partnership made the disguise unnecessary. She kept working past her hundredth birthday, and died at 104 having watched the railroads she analyzed consolidate from dozens into a handful.

When Siebert sought an NYSE seat in 1967, the first nine of the ten men she asked to sponsor her application declined. The exchange then added a novel condition: a bank letter promising to lend her $300,000 of the record $445,000 seat price — while the banks refused to commit until the exchange admitted her. She broke the catch-22, and on 28 December 1967 became the exchange's first woman member alongside 1,365 men. For nearly a decade, she liked to note, the ladies' room nearest the floor remained a converted phone booth.

Ogunlesi clerked for US Supreme Court Justice Thurgood Marshall in 1980 — widely described as the Court's first non-American clerk — before choosing finance over law. At First Boston, the assignment that made his name was one nobody wanted: years advising on the financing of the Nigeria LNG project, proof that unfashionable, difficult markets build singular franchises. Two decades later his infrastructure fund bought Gatwick Airport for about £1.5 billion in 2009, and BlackRock's 2024 acquisition of GIP made him one of the most powerful investors in world infrastructure.
