Benjamin Harrison (August 20, 1833 – March 13, 1901) was an American politician and lawyer who served as the 23rd president of the United States from 1889 to 1893. He was a grandson of the ninth president, William Henry Harrison, creating the only grandfather–grandson duo to have held the office. He was also a great-grandson of Benjamin Harrison V, a founding father who signed the United States Declaration of Independence. One of the first appointments Harrison was forced to reverse was that of James S. Clarkson as an assistant postmaster. Clarkson, who had expected a full cabinet position, began sabotaging the appointment from the outset, gaining the reputation for 'decapitating a fourth class postmaster every three minutes'. Clarkson himself stated, 'I am simply on detail from the Republican Committee ... I am most anxious to get through this task and leave.' He resigned in September 1890.
