Oswald Jacoby

Oswald (Ozzie, Jake) Jacoby (pronounced /ˈdʒækəbi/) (December 8, 1902 – June 27, 1984) was an American contract bridge player and author, considered one of the greatest bridge players of all time. He also excelled at, and wrote about, other games including backgammon, gin rummy, and poker.

Born in Brooklyn, he was taught to play whist at the age of six and played his first bridge at ten. During World War I, he joined the army at 15 by lying about his age but spent most of his time there playing poker. Dropping out of Columbia University as a math major to become an actuary, he became the youngest person ever to pass the examination of the Society of Actuaries at the age of 21. Having an exceptional aptitude for mathematics, Jacoby could multiply three and four digit numbers in his head without benefit of paper. During World War II and the Korean War, he applied these abilities to counterintelligence and cryptanalysis being referred to as a human computer; later, he lectured on probability at M.I.T. and wrote books on mathematics. However, his passion, his lifelong focus, was games, especially bridge.
