Cocoanut Grove fire

The Cocoanut Grove was Boston's premier nightclub during the post-Prohibition 1930s and 1940s. On November 28, 1942, this club was the scene of the deadliest nightclub fire in US history, killing 492 people (which was 32 more than the building's authorized capacity) and injuring hundreds more. The enormity of the tragedy shocked the nation and briefly replaced the events of World War II in newspaper headlines. It led to a reform of safety standards and codes across the country, and major changes in the treatment and rehabilitation of burn victims.
