Theodore Roosevelt Jr. (October 27, 1858 - January 6, 1919) was an American politician, statesman, soldier, conservationist, naturalist, historian, and writer who served as the 26th president of the United States from 1901 to 1909. He previously served as the 25th vice president under President William McKinley from March to September 1901 and as the 33rd governor of New York from 1899 to 1900. Assuming the presidency after McKinley's assassination, Roosevelt emerged as a leader of the Republican Party and became a driving force for anti-trust and Progressive policies. When running as the third-party Progressive (Bull Moose) candidate for president of the United States in 1912, Theodore Roosevelt recorded a number of campaign speeches made in August of 1912, including "The 'Abyssinian Treatment' Administered to Standard Oil" and "Why the Trusts and Bosses Oppose the Progressive Party," a criticism of 1912 presidential election opponent, Woodrow Wilson, and a greeting to the American Boy's Progressive League on March 4, 1913.
