Benjamin Harrison was an American politician and lawyer who served as the 23rd President of the United States from 1889 to 1893; he was the grandson of the ninth president, William Henry Harrison, creating the only grandfather-grandson duo to hold the office.
Before ascending to the presidency, Harrison established himself as a prominent local attorney, Presbyterian church leader, and politician in Indianapolis, Indiana.
During the American Civil War, he served in the Union Army as a colonel, and was confirmed by the U.S. Senate as a brevet brigadier general of volunteers in 1865. Harrison unsuccessfully ran for governor of Indiana in 1876. The Indiana General Assembly elected Harrison to a six-year term in the U.S. Senate, where he served from 1881 to 1887.
