The Lemp family's century-long brewery dynasty in St. Louis ended in tragedy—four family members died by suicide, and their mansion became one of America's most haunted houses. As the empire crumbled during Prohibition, a curse seemed to follow the Lemps through the generations. William J. Lemp built his brewery from a grocery store into a $106 million operation by 1886, but his grief over his favorite son Frederick's death in 1901 led him to shoot himself three years later.
