Hoover grew the FBI into a powerful crime-fighting organization with advancements in fields such as forensic science and fingerprint files. He became a controversial figure for his many abuses of the considerable power he gained, as well as his relationship with Clyde Tolson, a man Hoover described as his "alter ego." They often went out to dinner or night clubs together, and when Hoover died on May 2, 1972, Tolson moved into Hoover's home and accepted the American flag draped over his casket. They are buried a few yards apart from each other in the Congressional Cemetery. Notwithstanding this close relationship with Tolson, Hoover was a vocal leader in the “war on gays,” a contradiction noted by several scholars.
