Thomas Collier Platt, 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.

Theodore Roosevelt Jr., often referred to as Teddy or by his initials, T. R., was an American politician, statesman, conservationist, naturalist, and writer who served as the 26th president of the United States from 1901 to 1909. He previously held various positions in New York politics, rising up the ranks to serve as the state's 33rd governor for two years. He later served as the 25th vice president under President William McKinley for six months in 1901, assuming the presidency after McKinley's assassination. As president, Roosevelt emerged as a leader of the Republican Party and became a driving force for anti-trust and Progressive policies.
