July 14, 1850. At a swanky hotel in Apalachicola, Florida, the French consul is throwing a Bastille Day party, and he's promised his guests ice-cold champagne. There's just one problem: the town's ice shipment is delayed, and in 1850, you can't simply make ice. Or can you? Enter Dr. John Gorrie, a country physician who's spent years waging a private war against heat itself, convinced that cooling the air could stop the deadly fevers ravaging his town.

How did a doctor on the Florida frontier invent artificial cooling and take on the "Ice King" of New England? And why has history nearly erased his name?

Special thanks to Bern Nagengast, technology historian and author; and Linda Thompson, docent at the Raney House Museum in Apalachicola, Florida.
