Robert Todd Lincoln (August 1, 1843 – July 26, 1926) was an American lawyer and Secretary of War. He was the first son of President Abraham Lincoln and his wife, Mary Todd Lincoln. Born in Springfield, Illinois, United States, he was the only one of Lincoln's four sons to live to be an adult. He was a bright lawyer, and mostly served railroad interests. He was (1897–1911) president of the Pullman Company. He was quiet and shy. Because of this, he never tried to be a president, but he was minister to Great Britain (1889–93). Most of his last 20 years were spent at Hildene, his estate near Manchester, Vermont.
