Selling Frozen Ponds to the Tropics
In 1806, the New England businessman Frederic Tudor shipped ice to the Caribbean island of Martinique, hoping to sell it to wealthy European elites there. He had built an ice house specially for the purpose. The idea was, on its face, absurd: harvest frozen pond water in Massachusetts and sell it where ice had never existed.
It worked. Over the following years the trade widened to Cuba and the Southern United States, with other merchants joining Tudor in cutting and shipping New England ice.
Through the 1830s and 1840s it expanded far beyond that, with shipments reaching England, India, South America, China and Australia. Tudor made a fortune from the India trade specifically, and brand names such as Wenham Ice became famous in London. The ice was cut from the surface of ponds and streams, stored in ice houses, then sent onward by ship, barge or railroad — an entire industry built on a substance that is trying to destroy itself the whole way.
Ninety Thousand People and a Million Tons
By the end of the 19th century the scale had become genuinely industrial. At its peak the U.S. ice trade employed an estimated 90,000 people, in an industry capitalised at $28 million — about $660 million in 2010 money.
The storage was equally serious: ice houses capable of holding up to 250,000 tons each, which is 220 million kilograms of frozen water sitting in a single building waiting for summer.
America was not alone. As U.S. ice exports diminished after 1870, Norway became the major player in the international market, shipping large quantities to England and Germany, and eventually exporting a million tons of ice a year — drawing on a network of artificial lakes built for the purpose. Norway became the largest exporter of ice in the world, sourcing from polar regions where it could be cut year round rather than only in winter.
The Business That Rebuilt Dinner
The ice trade did not merely chill drinks. It restructured what people could eat.
Ice began to be used in refrigerator cars by the railroad industry, and that single application transformed American meat. The meat packing industry around Chicago and Cincinnati could now slaughter cattle locally and ship the dressed meat onward to domestic and international markets, rather than moving live animals.
The effects spread across every perishable trade:
- Chilled rail cars and ships created a national industry in vegetables and fruit that had previously been consumable only locally
- U.S. and British fishermen began preserving catches in ice, enabling longer voyages and bigger catches
- The brewing industry became operational all year round instead of seasonally
Networks of ice wagons handled the last step, distributing to households and smaller commercial customers. A whole category of new drinks and foods followed.
Killed by the Thing It Made Possible
The ice trade occupied a very specific historical window: it could only flourish between the development of reliable transportation and the development of widespread mechanical refrigeration. Open that second door and the industry has no reason to exist.
Competition grew slowly, in the form of artificially produced plant ice and mechanically chilled facilities. Unreliable and expensive at first, plant ice began successfully competing with natural ice in Australia during the 1850s and India during the 1870s. By the outbreak of the First World War in 1914, more plant ice was being produced in the U.S. each year than was naturally harvested.
The war brought a temporary production bump, but the interwar years finished the job — above all the widespread adoption of domestic mechanical refrigerators, which caused the total collapse of the international ice trade. Harvesting survived only in isolated rural areas without electricity, where fridges were impossible, plant ice uneconomic, and natural ice usually free of pollutants. Some of that continued until after the Second World War. Today ice is cut mainly for ice carving and ice festivals, and almost nothing remains of the 19th-century network.
