Canned Food
In 1795, the French government, concerned about the limiting
availability of large quantities of food during military campaigns, offered a
cash award to inventors for an efficiently cheap method of food preservation.
Over the next 15 years, Nicolas Appert, a Parisian confectioner, experimented
with various techniques using glass bottles; in 1810, he was awarded the prize
for a process similar to pasteurization known as “appertisation,” in which the
bottles were tightly sealed with a vise and placed in boiling water to cook the
contents. As Appert's model became more widespread, Peter Durand, a British
merchant and inventor, patented an improved process utilizing tin canisters
later that same year. In 1812, Durand sold the patent to British industrialists
John Hall and Bryan Donkin, who began producing canned food for the British
army; six years later, Durand re-patented his invention in the United States.
By 1822, canned food became a recognizable domestic staple in Britain, France
and the U.S., and a fundamental necessity in conflicts from the (original) Crimean
War to the Second World War.
Microwave Oven
Working for the Raytheon Corporation after World War II, Dr.
Percy Spencer accidentally discovered the practical application of microwave
radiation as a by-product from his research on radar technology. Noting that a
candy bar in his pocket melted when exposed to the radiation, he was spurred to
conduct further experiments on a way to rapidly cook food. Called the
“Radarange,” Tappan, under a patent-license with Raytheon, began manufacturing units
designed for home use starting in 1955. However, it would take another twelve years
to develop a commercially viable countertop oven, introduced by the Amana
Corporation, a Raytheon subsidiary, in 1967.
Nylon
Created by DuPont's Wallace Carothers, nylon was an
anticipatory invention during the 1930s intended as a synthetic replacement for
scarce Asian silk due to the impending Second World War. It was introduced
commercially in a nylon-bristled toothbrush in 1938, followed more notably two
years later as women’s stockings. During the war, it was used extensively in
the production of parachutes, as well as other military equipment like tires
and protective gear. From rope to dress shirts, nylon's application in modern
society is now an inescapable reality.
Cargo Pants
A modern fashion trend, cargo pants (and the variation of
shorts) were originally created for military use in the late 1930s. Designed
for use by British military personnel, particularly paratroopers, the
large-pocketed pants made it easier to carry military equipment like portable
communication devices and extra ammunition. Unlike nylon stockings, which were
an immediate hit on the fashion scene in the 1940s, it would take another sixty
years for cargo pants to go from functional to fashionable.
WD-40
In 1953, Norm Larsen, founder of the Rocket Chemical
Company, invented this handy lubricant as a water displacement ("WD")
and corrosion inhibitor for the Atlas Intercontinental Ballistic Missile. Allegedly,
it was his 40th attempt to perfect the formula, which is a trade
secret; to avoid full disclosure of its ingredients, it has never been
patented. Based in San Diego, California, Larsen’s invention became
commercially available in the city’s hardware stores five years later.
