The Omni Parker House Hotel opened in 1855 and has ever since been a popular spot for literary dignitaries, politicians and celebrities. Now owned by Omni hotels and resorts, in the 19th century, The Parker House housed The Saturday Club, a group for Boston's literary society. The likes of Henry Wadsworth Longfellow and Ralph Waldo Emerson would meet there on Saturday nights to read and discuss literature. One American author whom the group famously excluded was Edgar Allen Poe. Lincoln's assassin, John Wilkes Booth was once a guest and Charles Dickens rehearsed his first public reading of A Christmas Carol in a mirror on its fifth floor. The floor is now said to be haunted by strange happenings; elevators are constantly and anonymously called to the fifth floor.
