Arnold Rothstein was a central figure in the history of American organized crime. 
Rothstein was born in New York City on January 17, 1882. His father, Abraham Rothstein, was an affluent Jewish businessman known as "Abe the Just." While his brother Harry studied to become a rabbi, Arnold focused on mathematics. He was a highly skilled mathematician, though he had little interest in traditional schooling. This mathematical talent likely helped his later success in gambling and finance. He began gambling as a child, often to defy his father's wishes.
By the age of 28, Rothstein had established a casino in Manhattan's Tenderloin district. He also invested in a horse racing track in Havre de Grace, Maryland. He became a millionaire by age 30 through these ventures. Rothstein built a massive network of informants to gather intelligence. He was willing to pay a high premium for any useful information. This information allowed him to stay ahead of competitors and law enforcement.
One of the most famous controversies involves the 1919 World Series. This event is known as the "Black Sox Scandal." It is alleged that Rothstein's agents paid members of the Chicago White Sox to lose the series to the Cincinnati Reds. Rothstein reportedly bet against his own players and made a massive profit. Some sources suggest he won roughly $350,000 from the fix. While he was summoned to testify before a grand jury, prosecutors could not find enough evidence to indict him. The case was eventually dismissed, but the players involved were permanently banned from Major League Baseball.
Rothstein also faced suspicion regarding horse racing events, such as the 1921 Travers Stakes. He owned a popular horse named Sporting Blood under the name "Redstone Stable." During the race, a trainer named Sam Hildreth allegedly manipulated the odds to benefit Rothstein. By scratching a top contender at the last moment, the odds for Sporting Blood rose significantly. Rothstein reportedly collected over $500,000 in bets and the race purse. However, these conspiracy theories were never legally proven.
The era of Prohibition provided a massive opportunity for Rothstein's expansion. Prohibition was a period when the manufacture and sale of alcohol were illegal in the United States. Rothstein became a major figure in bootlegging and the narcotics trade. He used a fleet of transatlantic freighters to import illegal Scotch whisky. He also owned several speakeasies, which were establishments that served illegal alcohol. Rothstein acted as a mentor to future crime bosses like Lucky Luciano and Meyer Lansky. By 1925, his reported wealth exceeded $10 million, which is worth about $162 million today.
Rothstein's life ended following a violent dispute over gambling debts. On November 4, 1928, he was shot during a meeting at the Park Central Hotel in Manhattan. The shooting was reportedly linked to a high-stakes poker game in October. Rothstein allegedly owed approximately $320,000 and refused to pay the debt. He died two days later at the New York Polyclinic Hospital. While a man named George "Hump" McManus was arrested, he was later acquitted due to a lack of evidence.
The death of Rothstein caused a major shift in the American underworld and political landscape. His massive criminal empire was broken up and distributed among other organizations. This included groups led by his former associates, such as Bugsy Siegel and Frank Erickson. His absence also contributed to the downfall of Tammany Hall, a powerful New York political machine. The collapse of this machine helped lead to the rise of the reformer Fiorello La Guardia, who became Mayor of New York City in 1933. Rothstein's life even inspired fictional characters, such as Meyer Wolfsheim in F. Scott Fitzgerald's novel, *The Great Gatsby*.
