Robert Todd Lincoln
Robert Todd Lincoln (August 1, 1843 – July 26, 1926) was an American politician, lawyer, and businessman.
The first son of President Abraham Lincoln and Mary Todd Lincoln, Robert Lincoln was born in Springfield, Illinois, and graduated from Harvard College before serving on the staff of Ulysses S. Grant as a captain in the Union Army in the closing days of the American Civil War.
After the war, Lincoln married Mary Eunice Harlan, and they had three children together, two of whom survived to adulthood.
Following completion of law school in Chicago, he built a successful law practice, and became wealthy representing corporate clients.
Active in Republican politics, and a tangible symbol of his father's legacy, Lincoln was often spoken of as a possible candidate for office, including the presidency, but never took steps to mount a campaign.
The one office to which he was elected was town supervisor of South Chicago, which he held from 1876 to 1877; the town later became part of the city of Chicago.
Lincoln accepted appointments as secretary of war in the administration of James A. Garfield, continuing under Chester A. Arthur, and as United States Ambassador to the United Kingdom (with the role then titled as "minister") in the Benjamin Harrison administration.
Lincoln served as general counsel of the Pullman Palace Car Company, and after founder George Pullman died in 1897, Lincoln became the company's president.
After retiring from this position in 1911, Lincoln served as chairman of the board until 1922.
In Lincoln's later years he resided at homes in Washington, D.C. and Manchester, Vermont; the Manchester home, Hildene, was added to the National Register of Historic Places in 1977.
In 1922, he took part in the dedication ceremonies for the Lincoln Memorial.
Lincoln died at Hildene on July 26, 1926, six days before his 83rd birthday, and was buried at Arlington National Cemetery.
