Thomas Edmund Dewey was a noted American lawyer, prosecutor, and politician. He served as Chief Assistant U.S. Attorney for the Southern District of New York and as 33rd District Attorney of New York County. He gained nationwide attention for his relentless effort in prosecuting American Mafia and criminals. He prosecuted Mafioso kingpin Charles "Lucky" Luciano on forced prostitution charges. The latter was slapped with a thirty-year prison sentence. Dewey’s successful racket-busting career helped him win three terms as Governor of New York. A seasoned Republican Party member, Dewey was the party’s nominee for President in 1944 and 1948, but he lost on both occasions. He played instrumental role in getting Dwight D. Eisenhower the Republican presidential nomination in 1952, and also helped the latter in his landslide victory over Democrat Adlai Stevenson II, thus ending a two decade long winning spree of the Democratic Party. Dewey remained a leader of the moderate faction of the Republican Party.
