The Origins of Refrigeration

* Yellow Fever Treatment (1841): Dr. John Gorrie treated yellow fever patients with suspended ice in Florida.
* Ice Trade (1805-1856): Boston merchant Frederic Tudor supplied ice to islands, refining methods and expanding to other destinations.

Innovations and Advancements

* Gorrie’s Piston-Based Compressor (1840s): Gorrie experimented with a piston-based compressor to produce sub-ambient temperatures that froze water in salt solution.
* James Harrison’s Improved Design ( Late 1800s): Harrison improved the design by using a refrigerant that evaporated and condensed in a closed loop, producing large amounts of ice daily.

The Impact of Refrigeration

* Mass-Market Refrigerator (1927): The first mass-market refrigerator appeared, rapidly adopted to 85% of U.S. homes by 1944.
* Preservation and Scientific Advancements: Artificial refrigeration enabled preservation of food and medicine, and facilitated scientific advances in MRI, particle accelerators, and PCR.

Conclusion

* Refrigeration has fundamentally changed food distribution, medicine, and technology, offering cleaner, controllable production.
