Joseph Hobson Jagger (1830-1892) - A British Engineer, referred to as, but not an exclusive holder of the title of The Man Who Broke the Bank at Monte Carlo. One of the most well known among roulette enthusiasts.He was born in September 1829 in the village of Shelf near halifax, Yorkshire.
In 1873, Jagger hired six clerks to clandestinely record the outcomes of the six roulette wheels at the Beaux-Arts Casino at Monte Carlo, Monaco. He discovered that one of the six wheels showed a clear bias, in that nine of the numbers (7, 8, 9, 17, 18, 19, 22, 28 and 29) occurred more frequently than the others. He therefore placed his first bets on 7 July 1875 and quickly won a considerable amount of money, £14,000 (equivalent to around 50 times that amount, or £700,000 in 2005).
Over the next three days, Jagger amassed £60,000 in earnings with other gamblers in tow emulating his bets. In response the casino rearranged the wheels, which threw Jagger into confusion. After a losing streak, Jagger finally recalled that a scratch he noted on the biased wheel wasn't present. Looking for this telltale mark, Jagger was able to locate his preferred wheel and resumed winning.
Counterattacking again, the casino moved the frets, metal dividers between numbers, around daily. Over the next two days Jagger lost and gave up, but he took his remaining earnings, two million francs, then about £65,000 (around £3,250,000 in 2005), and left Monte Carlo never to return.
Jagger resigned from his job at the mill and invested his money in property. He is buried at Bethel Church, Shelf.
