The most famous address in America—1600 Pennsylvania Avenue—is also perhaps the country’s most famous haunted house. Presidents, first ladies, White House staff members and guests have reported feeling ghostly presences, hearing unexplained noises and even running into actual apparitions—even on the way out of the bathtub, in one particularly famous case.

Ghosts of Abigail Adams & David Burns

Abigail Adams and her husband John, the second president of the United States (1797-1801), moved to 1600 Pennsylvania Avenue from the former U.S. capital in Philadelphia. At the time, Washington, D.C. was still just a town, built mostly on swampy land on the banks of the Potomac River. Because the East Room of the new White House was the warmest and driest, Abigail used it to hang the wash. Her ghost, clad in a cap and lace shawl, has reportedly been seen heading towards the East Room, arms outstretched as if carrying laundry.

Did you know? Lincoln, who is believed to have attended only two of the séances his wife held in the White House, actually foresaw his own death more than once, including in a dream he had shortly before he was killed.

A lesser-known early White House personality who has been said to haunt its halls was David Burns, who sold the government most of the land on which the city of Washington—including the presidential residence—was built. Lillian Rogers Parks, a seamstress who chronicled her 30-year career working at the White House in a 1961 memoir, told the story of a valet to President Franklin D. Roosevelt who reportedly heard a disembodied voice coming from a distance in the Yellow Oval Room, saying “I’m Mr. Burns.” During Harry S. Truman’s administration, a guard heard a similar voice; thinking it was then-Secretary of State James Byrnes, he went looking for him, only to learn that the secretary hadn’t been at the White House that day.

Andrew Jackson & Harry Truman’s Ghosts

In 1824, Andrew “Old Hickory” Jackson was defeated by John Quincy Adams in one of the most contentious presidential elections in history. Elected president four years later, the surly Jackson continued to hold grudges against those who had supported his opponent. In the early 1860s, First Lady Mary Todd Lincoln–who believed strongly in the occult, and reportedly held séances in the White House to commune with the spirits of her dead sons–told friends she had heard Jackson stomping and swearing through the halls of the presidential residence. The Rose Room, Jackson’s bedchamber while he was president, is believed by some to be one of the most haunted rooms in the White House.

Jackson’s ghostly presence also showed up in the White House correspondence of Harry Truman, America’s 33rd president. In June 1945, just two months into his first term, Truman wrote to his wife Bess of the spooky quality of his new residence: “I sit here in this old house and work on foreign affairs, read reports, and work on speeches–all the while listening to the ghosts walk up and down the hallway and even right in here in the study. The floors pop and the drapes move back and forth–I can just imagine old Andy [Jackson] and Teddy [Roosevelt] having an argument over Franklin [Roosevelt].”

The Ghost of Abraham Lincoln

By far the most frequently reported sighting in the White House over the years has been the ghost—or at least the presence—of the celebrated 16th president, Abraham Lincoln, whose life was cut tragically short by an assassin’s bullet in April 1865. Grace Coolidge, wife of President Calvin Coolidge (1923-29), was the first person to say she had actually seen Lincoln’s ghost. According to her, the lanky former president was standing looking out a window of the Oval Office, across the Potomac to the former Civil War battlefields beyond. Lady Bird Johnson, wife of President Lyndon Johnson (1963-69), reportedly felt Lincoln’s presence one night while watching a television program about his death.

Most notably, sightings of Lincoln’s ghost were frequently reported during the long administration of Franklin D. Roosevelt (1933-45), who also presided over his country during a time of great upheaval. First Lady Eleanor Roosevelt used the Lincoln Bedroom as her study, and said she would feel his presence when she worked there late at night. During her visit to the White House, Queen Wilhelmina of the Netherlands heard a knock on her bedroom door in the night; when she answered it, she reportedly saw Lincoln’s ghost, wearing his top hat, and fainted dead away. British Prime Minister Winston Churchill, who visited the White House more than once during World War II, told a story of emerging naked from his evening bath smoking his customary cigar, only to find a ghostly Lincoln sitting by the fireplace in his room.

When Lillian Rogers Parks, the seamstress, once investigated the sound of someone pacing an upper level of the White House, another staff member told her the room in question had been unoccupied, and “that was old Abe pacing the floor.” Psychics have speculated that Lincoln’s spirit remains in the White House to be on hand in times of crisis, as well as to complete the difficult work that his untimely death left unfinished.
