Can you name the most famous ghost of the White House?

The Abraham Lincoln ghost is by far the most famous spirit to haunt the White House. Probably the first known sighting of the Lincoln apparition at the White House was recorded in a newspaper story related by doorman Jerry Smith in 1903. Sightings usually place Abraham Lincoln in the Lincoln Bedroom and Yellow Oval Room. First Lady Grace Coolidge, Prime Minister Winston Churchill, and Queen Wilhelmina of the Netherlands claimed to have seen Lincoln. The first families have had great fun with Lincoln’s ghost and pulled pranks on guests staying in the Lincoln bedroom over the years.
