How nylon was created

Plastic's history began with an inventor seeking a $10,000 prize offer

In 1869, the first synthetic polymer—celluloid—was created as a substitute for ivory in billiard balls. It became the historical catalyst for the eventual manufacturing of plastics everywhere as an alternative to the depletion of other natural resources, including tortoiseshell and horns.

The pharmaceutical industry evolved, in part, from the discovery of synthetic dyes

In 1856, a chemist accidentally discovered mauveine, the world’s first synthetic dye, while trying to make quinine to treat malaria. The synthetic dyes that followed helped reveal germs under microscopes, paving the way for modern imaging techniques and breakthrough treatments, such as antibiotics.

The most common type of 3D printer fabricates objects using plastic

At the consumer level, the most common printing method is fused deposition modeling, which builds objects by melting an extruding thermoplastic filament that is deposited in layers. For industrial applications, selective laser sintering, which uses a laser to fuse particles of polymer powder (e.g., nylon), is preferred.

LSD (better known as acid) was created in 1938 by Swiss chemist Dr. Albert Hofmann

Lysergic acid diethylamide, better known as LSD or acid, was first developed synthetically in 1938 by Swiss chemist Dr. Albert Hofmann. It's since become a linchpin for an entire aesthetic, fueled a counterculture movement, and is being studied for potential therapeutic uses.

Penicillin production was just behind the atom bomb in wartime priorities

By 1943, the US War Department made penicillin its second-highest priority—just after the Manhattan Project. Producing enough of the antibiotic for the D-Day invasion became a central mission of Allied science and industry.

Monsanto got its start in the early 1900s producing saccharin

The company was originally called Monsanto Chemical Works and was founded in 1901 by John Francis Queeny who was then a wholesale drug buyer. He named the company Monsanto for his wife's maiden name. At first, the company began producing saccharin with borrowed equipment and secondhand machines, aiming to produce domestically what was then being imported from Germany.

World War II innovations helped advance car racing

Modern American auto racing began in the 1920s with bootleggers modifying cars to outrun authorities. World War II innovations like better engines and surplus parts fueled post-war racing. By 1947, Bill France Sr. founded NASCAR, creating a unified league with consistent rules, transforming stock car racing into one of America’s favorite sports.

Thomas Edison created the first strand of electric Christmas lights in 1880

Edison strung electric bulbs outside his laboratory in 1880, and his business partner Edward H. Johnson first wrapped a tree in lights in 1882. It wasn’t until the lights were commercialized in 1917 that they became common in household Christmas decorations.

A Nantucket woman helped build Macy’s

Margaret Getchell, an early Macy’s superintendent, was among the first female executives in the American retail industry. Getchell (who was distantly related to Macy’s founder RH Macy, although it’s unclear if the pair knew that when she was hired) helped shape Macy's as an early employee.

The centuries-old history of titanium white goes back to the Inca

Titanium white can be found in items ranging from paint to pills. Though it was created in New York in 1908, the pigment was first used hundreds of years earlier by the Inca, according to this article.

Scientists create the first CRISPR-modified spider to enhance its silk proteins

A research group at the University of Bayreuth used CRISPR-Cas9 to genetically modify spiders to produce glowing red silk. Spider silk is five times stronger than steel by weight, and this research paves the way for developing new silk functionalities.

Local limestone made waterproof cement for the Erie Canal

In 1818, engineer Canvass White discovered that limestone near Chittenango, New York, could be processed into hydraulic (or waterproof) cement. This breakthrough replaced costly European imports, enabling watertight locks and aqueducts and revolutionizing American construction.

The term 'artificial intelligence' was coined in 1956

Dartmouth professor John McCarthy introduced the term during a summer workshop aimed at exploring how to make machines perform human-like tasks. Two years later, Perceptron Mark I became one of the first neural network machines.

At the beginning of the 20th century, a group of young men ate standard American food—replete with food additives like borax and formaldehyde—as part of government research to better understand food safety.

6 union history facts

Founded in 1794, the Federal Society of Journeymen Cordwainers (who were leather workers and cobblers) is considered to be the first union in the United States.

The applications and industrial uses of graphene, the single-atom-thick material

Shortly after its discovery in 2004, the strength, flexibility, optical properties, and conductivity of this thin layer of carbon atoms earned it the designation of a "wonder material," but breakthroughs in its use have taken decades of research. As of 2026, graphene-enhanced electronic sensors, optical microchips, concrete, and supercapacitors are available, though scale production challenges remain.

Twain invented a clasp that's still used for bras

In 1871, Twain patented an “improvement in adjustable and detachable straps for garments.” Although he intended it for “vests, pantaloons, or other garments requiring straps,” it’s mostly used today in brassieres.

How scientists earned themselves a Nobel Prize by discovering what destroyed ozone

In 1974, chemists Mario Molina and F. Sherwood Rowland showed that chlorofluorocarbons—then used as aerosol propellants, refrigerants, and industrial solvents—rise into the stratosphere and, upon being struck by ultraviolet radiation, release chlorine atoms, which break apart ozone molecules. Their work earned them the Nobel Prize in chemistry in 1995.

30,000 men known as the 'League of Broke Husbands' once protested Dior's luxury fashion designs

In the 1940s, these men living in post-war France were angry about the waste and cost of the fabric needed to make its luxury clothing. Today, Dior is owned by luxury conglomerate LVMH.

A US Department of Defense research lab developed the technology for the dark web

Although encryption existed to mask the content of communications across the internet before the 1990s, those managing overseas network infrastructure could determine a spy's affiliation based on where they saw data sent to and received from. To keep this information secret, the US Naval Research Laboratory developed onion routing, which enabled anonymized web browsing. The release of the technology to the public obscured sensitive communications further by growing the volume of anonymous data.

Conditioners can help unshrink garments by lubricating fibers

Textile fibers relax and shrink due to heat and moisture, disrupting hydrogen bonds. While loosely knitted fabrics are more prone to shrinkage than tightly woven ones, synthetic fibres like polyester resist shrinkage due to their crystalline structure.

Nike was almost named ‘Dimension Six’

Jeff Johnson, the company’s first full-time employee, said the name came to him in a dream just before Blue Ribbon Sports filed a patent for the “Nike” football shoe. Nike cofounder Phil Knight wanted to name the company “Dimension Six,” but was ultimately convinced that a one-word name would be better. (Some users may experience a paywall.)

Modern genetic testing stems from a 1950s discovery about the cause of Down syndrome

Scientists found that an additional copy of chromosome 21 causes the disease and developed an approach to stain chromosomes so they could be manually sorted and counted, which is called karyotyping. The breakthrough discovery by Marthe Gautier, a young French doctor and cytogenetics researcher, was appropriated by a male colleague, who listed himself as the lead author of the study reporting the finding.

DNA may serve as a flame retardant by self-extinguishing some burning materials

When DNA burns, phosphate groups release phosphoric acid, and nitrogenous bases release ammonia. These molecules, along with the sugar in DNA's backbone, shift the combustion reaction toward the formation of intumescent char. This puffy, carbon-rich layer protects open flames from burning the material beneath.

Frozen burritos made the dish widely available in the 1950s

California native Duane Roberts, who also pioneered the frozen hamburger patty, invented the frozen burrito in 1956 to be easily prepared at fast food restaurants. This innovation also allowed it to be sold in supermarkets.
