Thomas Collier Platt (July 15, 1833 – March 6, 1910), also known as Tom Platt and Easy Boss, was an American politician who was a two-term member of the U.S. House of Representatives (1873–1877) and a three-term U.S. Senator from New York in 1881 and 1897 to 1909. He is best known as the "political boss" of the Republican Party in New York State in the late 19th century and early 20th century. Upon his death, the New York Times stated that "no man ever exercised less influence in the Senate or the House of Representatives than he," but "no man ever exercised more power as a political leader." He considered himself the "political godfather" of many Republican governors of the state, including Theodore Roosevelt.
Platt played a key role in the creation of the City of Greater New York, which incorporated together the boroughs of New York (Manhattan), Kings (Brooklyn), Queens, Richmond (Staten Island) and Bronx counties.
Early years

Platt was born to William Platt, a lawyer, and Lesbia Hinchman, in Owego, Tioga County, New York on July 15, 1833. State Senator Nehemiah Platt (1797–1851) was William Platt's brother.
William Platt, a successful attorney and strict Presbyterian, encouraged his son to enter the ministry. Accordingly, the young Platt was prepared for college at the Owego Academy and attended Yale College (1850–1852), where he studied theology but failed to earn a degree owing to ill health which forced his withdrawal. During the American Civil War, Platt's illness prevented him from serving in the Union military, but he raised money to support troops and actively urged support for the Lincoln Administration.
Platt became secretary and a director of the United States Express Co. in 1879 and was elected president of the company in 1880. He was president of the Board of Quarantine Commissioners of New York from 1880 to 1888 and was President of the Tennessee Coal & Iron Company for several years.
Early political career
Platt's political involvement began at the Republican Party's inception; he made his first appearance in politics in 1856 in the campaign of the party's first presidential candidate, John C. Frémont. and was a member of the New York Republican State Committee and Republican National Committee. By 1887, Platt was the de facto leader of New York's Republicans, where he developed a reputation as the "easy boss." Their legal separation was announced in 1906, with Platt agreeing to pay his estranged wife $75,000 in exchange for her dropping all financial claims upon him and dismissing a suit for divorce which had been previously filed. He retired from the Senate in 1909 and was stricken by what was diagnosed as an acute attack of Bright's disease on May 28, 1909, a case so severe that his doctor publicly predicted his patient's imminent demise.
Platt's body was interred in Evergreen Cemetery, Owego, New York. At the time of his death, he remained married to Lillian, but she received nothing in his will.
