Others who might be considered autodidacts include Andrew Carnegie, Winston Churchill, Bill Gates, Mark Zuckerberg, and Guglielomo Marconi. When the self-taught can achieve so much, it raises the question of whether we over-emphasize formal education? (Chernow also mentions Hamilton being an autodidact on pages 110, 206, and 682.)
(p. 42) Hamilton’s early itinerary in America closely mirrored the connections of Hugh Knox. Through Knox, he came to know two of New York’s most eminent Presbyterian clergymen: Knox’s old mentor, Dr. John Rodgers– an imposing figure who strutted grandly down Wall Street en route to church, grasping a gold-headed cane and nodding to well-wishers–and the Reverend John M. Mason, whose son would end up attempting an authorized biography of Hamilton. Through another batch of Knox introductory letters, Hamilton ended up studying at a well-regarded preparatory school across the Hudson River, the Elizabethtown Academy. Like all autodidacts, Hamilton had some glaring deficiencies to correct and required cram courses in Latin, Greek, and advanced math to qualify for college.
