What it argues
Bubble in the Sun is Christopher Knowlton's account of the Florida land boom of the 1920s, the single most spectacular speculative real estate bubble in American history before the 2000s. Between roughly 1920 and 1926, land prices in Florida — particularly in Miami, Palm Beach, and along the planned developments of men like Addison Mizner and George Merrick — rose at a pace that attracted speculators from across the country. At the boom's peak, a single lot could be resold multiple times in a single day. The bust, which arrived even before the 1929 crash, wiped out fortunes and left half-finished cities across the state.
Knowlton organizes the narrative around a cast of colorful central figures. Addison Mizner was a California architect with no formal training who invented the "Palm Beach Spanish" style that still defines much of South Florida's aesthetic and built Boca Raton from scratch as a planned luxury community. Carl Fisher was the Indianapolis motor entrepreneur who developed Miami Beach by dredging mangroves, importing soil, and marketing aggressively to the Midwest. George Merrick built Coral Gables, the most ambitious planned community of the era, with Mediterranean architecture, gondola canals, and an unrealized vision of a college town. D.P. Davis pulled off the audacious feat of creating two artificial islands in Tampa Bay and selling lots before the land was fully out of the water.
What it gets right
- 1.
The Florida land boom of the 1920s was driven by a combination of real demographic and climate attractions and classic speculative psychology — the belief that prices could only rise because they had been rising.
- 2.
Binder boys — speculators who purchased small deposits on lots and sold them before the full payment was due — were the mechanism of the bubble's acceleration and its first indicator of collapse.
- 3.
The major developers (Mizner, Fisher, Merrick, Davis) mixed genuine vision with promotional excess. The physical infrastructure they created outlasted the financial structures that funded it.
What it covers
Who wrote it
Christopher Knowlton is an American journalist and author who spent many years working for Fortune magazine before writing books on financial and cultural history. He is also the author of Cattle Kingdom: The Hidden History of the Cowboy West, a history of the cattle industry and the open-range era. Bubble in the Sun was the product of several years of research into the Florida land boom, drawing on newspaper archives, court records, and the papers of the major developers involved. Knowlton grew up in the northeastern United States and brings an outsider's perspective on Florida's recurring relationship with speculative excess.
