Henry Singleton

Teledyne; the original Outsider; opportunistic buybacks + conglomerate

Singleton co-founded Teledyne in 1960 and served as its chief executive for decades, compounding shareholder value at exceptional rates. He became the archetype for William Thorndike's 'Outsider' CEO framework, famed for reducing Teledyne's share count by roughly 90% through aggressive repurchases when the stock was cheap. Warren Buffett cited him as one of the greatest capital allocators who ever lived.
