The story
Jim Simons was a mathematics professor and Cold War code-breaker (NSA) before founding Monemetrics in 1978, later renamed Renaissance Technologies. His breakthrough insight: don't hire people who think about markets the way markets think about themselves. Hire linguists, mathematicians, and physicists. The Medallion Fund, launched in 1988, has generated ~66% gross annual returns (~39% net) for 30+ years — the best long-run investment record of any fund in history. It is closed to outside investors; only Renaissance employees can invest. The $10B Medallion Fund is adjacent to RenTec's larger external funds (RIEF, RIDA) which have much more modest performance.

No-finance rule formalized — only PhDs from other fields
RenTec explicitly refuses to hire people with finance or economics training. The reasoning: people who've worked in finance have priors that contaminate the model-building. Linguists, cryptographers, and signal-processing PhDs instead.
