Charles Leale

Charles Augustus Leale (March 26, 1842 – June 13, 1932) was a surgeon in the Union Army during the American Civil War and the first doctor to arrive at the presidential box at Ford's Theatre on April 14, 1865, after John Wilkes Booth fatally shot President Abraham Lincoln in the head. His prompt treatment allowed Lincoln to live until the next morning. Leale continued to serve in the army until 1866, after which he returned to his home town of New York City where he established a successful private practice and became involved in charitable medical care. One of the last surviving witnesses to Lincoln's death, Leale died in 1932 at the age of 90. Provided by Wikipedia
