Have you ever heard your grandma refer to the freezer as the “icebox?” She didn’t coin this phrase herself—she may have actually had a legitimate icebox in her home as a kid! This was an early method of refrigeration that people utilized to keep food cold before the modern refrigerator. Learn what role the icebox played in refrigeration history and how it helped lead to modern fridges and freezers.
The Early Days of Refrigeration
It’s hard to imagine planning meals without a convenient refrigerator in your kitchen. However, for countless generations, cooking and storing food had to be done without electric refrigeration.
To preserve perishable food, especially meat, Americans in the late 1700s began storing food in pits buried in the ground with huts built above them. Known as icehouses, these pits were filled with ice harvested from nearby lakes, which they could keep frozen all summer long by using straw for insulation and stone walls to reduce heat transfer.
What is an Icebox? Purpose & Technology
While icehouses served the wealthy upper class, there became a need for the average American to have access to refrigeration in their own homes. After all, keeping food chilled was proving to be the clear choice for food preservation. It beat out other methods such as salting, drying, and canning, which are labor-intensive and eliminate all signs of freshness from the food.
Thus, by the end of the 1800s, many households began storing perishable food in iceboxes. This was typically made of wood with a tin or zinc lining packed with straw, sawdust, cork, or seaweed for insulation. A large block of ice held in a compartment or tray near the top of the icebox kept any food stored along with it chilly for a reasonable period of time.
Iceboxes ranged in price from $15 to $50, depending on their sizes and features. Cheap models had a drip pan that users had to empty daily, while fancier versions had spigots for draining melted ice into a holding tank, which could then be used for drinking. Users replenished their supply of ice by purchasing blocks from an iceman.
The Advent of the Refrigerator
The discovery and harnessing of electricity in the late 1800s opened the floodgates to all kinds of innovations, including electric refrigeration. This technology allowed perishables to be kept cold indefinitely, and at a more consistent temperature for reliable food safety.
The earliest devices initially became available in the 1910s, but it wasn’t until the late 20s that the technology became honed enough to offer an affordable, dependable means of in-home electric refrigeration. The first fridge to become widely popular was made by General Electric in 1927, which customers could purchase for $520—over $7,000 in today’s money! Thanks to discounts made available by General Electric and other manufacturers, refrigerator sales grew steadily into the Great Depression when it was unthinkable to throw away leftovers.
By 1935, the era of electric refrigeration had truly begun, and by 1944, 85 percent of American households featured a refrigerator in the kitchen. But its predecessor, the icebox, lives on in the vernacular of our grandparents—at least for one more generation.
