Freddie Mercury (1946–1991), born Farrokh Bulsara, was verified through Britannica, QueenOnline, Britannica's Queen article, and History.com. Britannica confirms his Queen role, AIDS diagnosis in 1987, public announcement the day before death, and death in London on November 24, 1991. QueenOnline corroborates the official AIDS announcement, death from AIDS complications, and the Mercury Phoenix Trust created after his death. Britannica's Queen article confirms Queen's major works, Mercury's 1991 death from AIDS, and the Wembley memorial concert for AIDS awareness. His worth is the fusion of theatrical voice, communal performance, and a posthumous public-health echo that turned stigma into awareness and funding.
