Lemp: The Rise, Fall, and Long Afterlife of a St. Louis Brewing Dynasty

In 1840, a German immigrant grocer named Adam Lemp began brewing lager beer on Second Street in St. Louis. Two generations later, his family's brewery covered several city blocks above a natural cave. It shipped Falstaff beer around the world and made the Lemps one of the richest families in the Midwest. Within another generation, it was gone, sold at auction for a few cents on the dollar. By then the family had become better known for its deaths than its beer.

This is the full history of the Lemps and their brewery, from Adam's flight from his debts in Hesse to the autumn of 2026, when the Lemp Mansion was put up for sale after half a century with one owner. Drawing on National Register nominations, court opinions, government records, newspaper research, and the work of St. Louis historians, it follows:

- Adam Lemp's tangled finances and two families, and the cave beneath the city commons

- William J. Lemp's red-brick industrial empire and its pioneering refrigeration

- Falstaff, the shield, and the rivalry with Anheuser-Busch

- The deaths of Frederick, William Sr., Elsa, Billy, and Charles, told from the records, with the conflicts between sources laid out plainly

- The "Lavender Lady" divorce, the chalet at Alswel, and Edwin's private menagerie at Cragwold

- Prohibition, the 1922 auction, and the Falstaff and Lemp brand names after the family

- Cherokee Cave, the mouthwash magnate who turned it into a tourist attraction, and the interstate that sealed it

- The mansion's rebirth as a restaurant, inn, and one of America's best-known "haunted houses"

- The collapses at the brewery complex since 2020, and where things stand today

Throughout, the book separates documented history from legend. It shows where the ghost stories first appeared in print and which famous details have no source at all. It also includes a timeline, a text family tree, a guide to Lemp places, and a full list of sources.
