The Petersen House is a 19th-century federal style rowhouse located at 516 10th Street NW in Washington, D.C. On April 15, 1865, United States President Abraham Lincoln died there after being shot the previous evening at Ford's Theatre located across the street. The house was built in 1849 by William A. Petersen, a German tailor.
On the night of April 14, 1865, Lincoln and his wife 
Almarin Cooley Richards, superintendent of the Washington Metropolitan Police, was attending the performance and immediately began investigations. From the back parlor of the house, Richards interviewed witnesses and ordered the arrest of Booth.
Physicians continually removed blood clots which formed over the wound and poured out the excess brain fluid and brain matter from where the bullet had entered Lincoln's head in order to relieve pressure on the brain. However, the external and internal hemorrhaging continued throughout the night.
During the night and early morning, guards patrolled outside to prevent onlookers from coming inside the house. Lincoln's Cabinet members, Generals, and various members of Congress were allowed to see the President.
Lincoln died in the house on April 15, 1865, at 7:22 a.m., age 56. Individuals in the room when he died included his son Robert Todd Lincoln, Senator Charles Sumner, generals Henry Wager Halleck, Richard James Oglesby and Montgomery C. Meigs, and Secretary of War Edwin Stanton.
Since 1933, the National Park Service has maintained it as a historical museum, recreating the scene at the time of Lincoln's death. The bed that Lincoln occupied and other items from the bedroom had been bought by Chicago collector, Charles F. Gunther, and are now owned by and on display at the Chicago History Museum. However, replicas have taken their places. The bloodstained pillow and pillowcases are the ones used by Lincoln.
Today, the Petersen House is administered by the National Park Service as part of the
