The terrorist attack that killed 49 and wounded 53 in Orlando, Fla., was the largest mass killing of gay people in American history, but before Sunday that grim distinction was held by a largely forgotten arson at a New Orleans bar in 1973 that killed 32 people at a time of pernicious anti-gay stigma.

Churches refused to bury the victims’ remains. Their deaths were mostly ignored and sometimes mocked by politicians and the media. No one was ever charged. A joke made the rounds in workplaces and was repeated on the radio: “Where will they bury the queers? In fruit jars!”

Outpourings of grief from politicians and everyday people have followed the Orlando shooting, but for those who remember the fire in the New Orleans bar, the UpStairs Lounge, its lonely memory has loomed large over conversations about the carnage this week at the Pulse nightclub.
