Biographical / Historical

Arthur Fortunatus Cosby was a private in the 1st United States Volunteer Cavalry, also known as the Rough Riders, during the Spanish-American War, under the leadership of Theodore Roosevelt. In August, 1898, he was promoted to the role of Assistant Adjutant General, with the rank of Captain. Born in 1872 in San Francisco, California, Cosby was an 1894 graduate of Harvard College.

The Progressive Party was a third party in the United States formed in 1912 by former President Theodore Roosevelt following his loss of the Republican Party presidential nomination. The new party was known for progressive reforms such as campaign finance regulations, reduction of tariffs and the establishment of a social insurance system, support of an eight-hour workday, and women’s suffrage. After its defeat in the 1912 presidential election, the Progressive Party declined in membership and interest, disappearing fully by 1918. The Party’s common nickname was the “Bull Moose Party,” named for Roosevelt.
