The Man Who Got Us Addicted To Ice Cubes

Quick Overview

Frederic Tudor, the "Ice King," built a global monopoly transporting natural ice for decades until Dr. John Gorrie invented a machine using air expansion to create artificial ice cubes anywhere, ultimately paving the way for modern refrigeration and the cold chain, despite Tudor's efforts to destroy Gorrie's reputation.

Key Points: Dr. John Gorrie devised a method to create artificial ice by noticing that rapidly expanding air cools down, leading him to build a machine utilizing high-pressure, cooled air expansion to freeze salt water around fresh water molds, creating the world's first ice cube tray in the 1840s. Frederic Tudor, the "Ice King," established a global monopoly on transporting natural ice, shipping over 80 metric tonnes from Boston to the West Indies in 1806, though initially only half survived the journey. Tudor overcame initial business failures by proving the value of ice by giving it away to bartenders in the West Indies to make cold drinks, noting, "A man who has drank his drinks cold at the same expense for one week can never be presented with them warm again." Tudor expanded his empire significantly, shipping ice to Calcutta by 1833, making the ice trade the US's second-largest export by weight by the 1860s, which facilitated the growth of industries like meatpacking and popularized foods like iceberg lettuce via the newly established cold chain. Tudor actively suppressed Gorrie's invention by paying newspaper editors to publish scandalous articles, claiming Gorrie was trying to create ice "as good as God Almighty," causing Gorrie to die penniless. James Harrison later improved upon artificial cooling using the phase change principle—forcing a fluid to continuously evaporate and condense—which led to commercially successful machines superior to Gorrie's air-based design. The success of artificial cooling and the resulting cold chain revolutionized food distribution, allowing cities to eliminate local slaughterhouses and reorganized supply chains, exemplified by Chicago's growth from 30,000 people in 1850 to 1.7 million in 1900.
