Algonquin Hotel ghost stories

The Algonquin Hotel, opened in 1902 and famous for the Algonquin Round Table, has accumulated guest and staff reports of unexplained knocks, sightings, and other odd occurrences attributed to past residents and regulars. The hotel is referenced in numerous published accounts of New York hauntings and offers occasional guided histories that mention these stories. These claims are anecdotal and have not been scientifically verified.
