Why is it called a cooler? A deep dive into the chill history of the iconic American ice box

For countless Americans, summertime adventures are made possible by the trusty cooler – that plastic, metal or even fabric insulated box able to keep our drinks icy and food fresh for days out on the trail, at the cabin, or in the back of the station wagon.

This humble yet ingenious device has become an iconic piece of American culture. Songs have been written about coolers, they star in TV ads, and they enable tailgating at every pro football stadium.

But have you ever wondered…why is it actually called a cooler?

I did some deep historical digging to uncover the fascinating backstory behind this ubiquitous item. And along the way, I discovered some cool facts about everything from cooler slang to vintage designs.

Grab an ice-cold drink from your own trusty cooler, and let‘s chill out on a journey through the evolution of the cooler!

From ice houses to "coolers" – a definition centuries in the making

The Oxford English Dictionary cites the first printed use of the word "cooler" in 1576. It referred to "a vessel in which liquids or other things are set to cool."

Of course, people have needed to chill food and drink since ancient times. Blocks of lake ice were cut and stored in underground "ice houses" to preserve perishables in warmer months.

But it wasn‘t until the 19th century that ice harvesting and storage became an industry in America. New England and the Great Lakes region shipped ice all over the country via rail. Ice boxes became common household appliances.

By the early 1900s, manufacturers were experimenting with new ways to make portable ice boxes. A 1906 ad featured a "Portable Refrigerator" made from galvanized steel with cork insulation. But early portable models were still bulky.

It wasn‘t until the 1940s and 50s that the cooler really took the form we know today. Technological advancements like molded plastic and foam insulation combined to create affordable, lightweight and truly portable coolers for the postwar American public.

According to Merriam-Webster, the first known use of "cooler" to describe this new portable ice box device was in 1944. And the rest is history!

The rise of cooler companies after WWII

Following WWII, American industry shifted from supporting the war to making consumer goods. For businesses like Coleman, this meant pivoting from military manufacturing to innovative new outdoor recreational products.

Coleman began tinkering with portable ice chest technology in the mid-1940s, introducing steel coolers with dependable insulation. Their iconic green coolers became standard equipment for picnics, camping, fishing and hunting expeditions around the country.

In 1954, two visionary engineers in Denton, Texas filed a patent for a "Portable Ice Box Construction." This design by Bill Murphey and John Adams evolved into the pink and blue Igloo cooler – an icon of American ingenuity.

Coleman and Igloo dominated cooler sales throughout the 1950s and 60s as outdoor pursuits boomed. Over the ensuing decades, established brands and upstarts alike have driven cooler innovation and manufacturing.

The global cooler market size was valued at $4.4 billion in 2020. In the US alone, over 60 million coolers are sold each year ranging from personal lunch boxes to massive 140-quart party vessels!

How engineering innovations kept things cooler for longer

That first Coleman steel cooler from the 1940s worked okay thanks to its cork insulation. But keeping ice frozen for more than a day or two required bulkier walls.

Innovations in insulation materials over the decades drove the biggest leaps in cooler performance:

• Styrofoam: Dow Chemical‘s trademarked foam insulation debuted in the mid-1940s. Lightweight, cheap and fairly insulating, polystyrene foam panels were a game changer.

• Hard Plastics: High-density polyethylene and polypropylene plastics revolutionized both the inner shells and outer walls of coolers in the 80s and 90s.

• PUR foam: Polyurethane rigid foam provides superior insulation compared to polystyrene. High-end coolers from YETI and others use PUR foam.

• Vacuum-insulated panels (VIPs): The latest development – layers of insulation surrounding a vacuum. Prohibitively expensive for now, but likely the future!

Beyond insulation, engineers also fine-tuned cooler features like drainage systems, latches, hinges, handles and more. New materials like stainless steel and molded polymers made coolers lighter and more rugged.

The cooler you buy today represents decades of tinkering and optimizing to keep drinks and food colder longer!

The beauty of coolers: Art, film and the place in Americana

Beyond sheer utility, the classic cooler has become an iconic piece of American culture celebrated in art, movies and more:

• Pop artist Andy Warhol painted a Campbell‘s Soup Can cooler in 1962 as part of his famous series.

• The 1980 comedy film The Blues Brothers features John Belushi riding on top of a cooler in a classic scene.

• Colorado-based artist Travis Walker creates elaborate mosaic sculptures using broken cooler pieces. His Art of the Coolers highlights cooler aesthetics.

From folk songs like "Big Green Coleman Cooler" to decades of memorable TV commercials, the cooler holds a special place in American culture. It‘s both mundane yet iconic at the same time.

As author James D. Watts wrote in The People‘s Almanac Presents the Book of Lists, "The cooler is an example of something perfect in its simplicity. It does what it is supposed to do, and it does it perfectly."

Perfection through simplicity – what more could you ask for?

The evolution of cooler features and functions

Today you can buy coolers decked out with speakers, phone chargers, blender attachments, even solar panels!

But early cooler engineers stuck to the basics like insulation, hinges and handles in their designs. Let‘s explore how some key features evolved over the decades thanks to new materials and technologies:

Insulated lids: Early lids were made from the same material as the cooler body, providing minimal insulation. Foam injection-molded lids debuted in the 70s and 80s to boost cooling power. High-end coolers today have 2-3" of foam in the lid.

Hinges: Simple metal hinges eventually gave way to durable plastic hinges that are less prone to rusting. Recessed hinges further prevent snagging.

Handles: Original metal handles on steel coolers morphed into molded plastic handles that are lightweight and ergonomic. Some now have rope handles for easy carrying.

Latches: Basic metal latches transformed into specialized cam latches that compress the lid against the cooler body for a tighter seal, or even rubber latches that resist corrosion.

Drain plugs: Cork, rubber or metal drains got an upgrade in the form of threaded drain plugs that screw in and out for easier water drainage after ice melt.

Wheels: As coolers grew in size, integrally molded wheels and tow handles became essential for rolling them instead of heavy lifting.

Each innovation made coolers simpler to use and extended their cold-keeping capabilities. And there are surely more useful innovations to come!

The wine cooler – bringing vino to the masses

Beyond keeping beer and soda pop cold, the early 1980s saw coolers play a surprising role in mainstreaming wine in America.

Up until that point, wine was seen as a fancy European drink, especially among younger demographics. A new category called "wine coolers" helped change that perception.

These canned or bottled beverages combined red or white wine with fruit flavors, fizzy water and sweeteners like high-fructose corn syrup. The resulting drinks contained around 5% alcohol but tasted more like fruity sodas.

California winemaker Ernest Gallo was one of the first to recognize this opportunity, launching their Bartles & Jaymes wine coolers in 1984. The TV commercials starring the fictional Frank Bartles and Ed Jaymes became iconic.

Sales of wine coolers reached over $1.5 billion by 1987, surpassing the entire table wine category. But the craze was short-lived, fading by the early 1990s as consumers moved on to beers and ciders.

Still, those convenient wine coolers succeeded in "knocking wine off its elite perch," helping pave the way for a huge variety of flavored alcoholic beverages we enjoy today. The iconic cooler played a small but important role in American wine culture.

How to maximize cooler lifespan with proper care

In an age of disposable products and instant gratification, it‘s nice to know a quality cooler can last for decades if properly cared for. Here are my tips for keeping your cooler in top shape for the long haul:

• Clean thoroughly inside and out – especially the drain plug – after each trip using mild detergent, warm water and a soft brush. Rinse and dry completely.

• Deodorize periodically with a baking soda scrub or mild soap and water solution. Avoid harsh chemicals inside.

• Check fittings like hinges and handles for visible wear or wobbly connections. Tighten or replace parts as needed.

• Replace worn parts like drainage gaskets which can dry out and leak over time. Fix issues promptly to prevent bigger problems.

• Avoid overpacking which can put undue strain on walls and seals. Maximize cooling by leaving some air space.

• Secure the lid using elastic cords or bungees when transporting to prevent opening and spilling.

• Consider re-coating or re-lining the interior with an FDA food-grade coating every few years to maintain maximum insulation.

With some basic TLC, I know people still using vintage 1950s Coleman coolers they inherited from their grandparents! Proper care really pays off.

Gazing into the future of coolers

While the basic cooler concept has remained constant for decades, new materials and technologies promise to continue revolutionizing these trusty ice boxes:

• Advanced insulation: Aerogel composites, nano-foams and even "frozen smoke" insulation could enable extreme cold retention previously unthinkable.

• Smart coolers: Bluetooth connectivity and built-in sensors will allow coolers to monitor internal temp and automatically adjust cooling.

• Accessories: From blenders to dry ice makers to solar chargers, high-tech accessories will expand cooler functionality.

• Hybrid designs: More use of fabric, collapsible joints and interchangeable components will further improve portability.

• Personalization: Digital printing and custom injection molds will make one-of-a-kind cooler designs and color schemes easy to create.

• Clean energy: Solar panels and battery packs will make motorized coolers and even refrigeration possible off-grid.

Who knows – maybe one day coolers will actively pump in cold air or synthesize ice on demand! I‘ll toast to that idea with an ice-cold beverage from my cooler. 🍻

No matter how much coolers continue advancing, nothing beats the nostalgia of a vintage model handed down through generations of family memories. Even as an engineer myself, I have to admire the low-tech genius of those original simple steel ice boxes.
