President-Elect Lincoln Arrives In Washington

With his coat draped over his arm, American President-elect Abraham Lincoln (1809 - 1865) walks near a railroad engine with Scottish-born detective Allan PInkerton (1819 - 1884) and American lawyer Ward Hill Lamon (1828 - 1893), Washington, DC, February 23, 1861. Pinkerton, founder of the Pinkerton National Detective Agency, foiled a plot to assasinate Lincoln in 1861. Lamon, who practiced law with Lincoln in Illinois, served as the president's bodyguard in Washington and was famously not in the city on the night of Lincoln's assassination.
