Robert Todd Lincoln Beckwith (July 19, 1904 – December 24, 1985) was the great-grandson of Abraham Lincoln. In 1975, he became the last descendant of Lincoln when his sister, “Peggy” Beckwith, died without children. He did not attend college, yet was said to have earned a degree from the National University Law School (founded 1869 and merged to with George Washington University Law School in 1954) as an attorney. Despite this, he tended to list his profession as a “gentleman farmer of independent means” rather than as a lawyer. He served in the Coast Guard during World War II, which resulted in a lasting hobby in boating and sailing. He generally avoided the media and publicity. On one occasion, he stated that his real interests were boats, cars, and living a semi-wild life.
Beckwith’s first marriage, which lasted 30 years, was to an older widow whose son was only ten years his junior. His second wife had a child and named him Timothy Lincoln Beckwith, after his supposed father, but the claim was considered inconclusive after she refused for herself and her son to take blood tests. Robert Beckwith lived most of his life in Vermont and Washington, D.C. Robert “Bob” Beckwith died at the age of 81 on December 24, 1985 at around 6:05 pm, the last undisputed descendant of Abraham Lincoln.
