Nikola Tesla was born in modern-day Croatia and moved to the US in 1884

Despite promoting alternative current, Nikola Tesla did not invent it

The technology was developed by Hippolyte Pixii in 1832, almost 25 years before Tesla was born. Other myths about Tesla include that he invented the transformer, radio, and the induction coil, which was invented by Nicholas Callan in 1836.

Nikola Tesla embraced showmanship when promoting ideas ahead of their time

He once electrified himself during a live demonstration to illustrate the safety and power of alternating current, and his presentations often featured arcing coils, glowing lights, and bold claims about a future of wireless power.

Tesla's alternating current power's most of the world's electric grids

In 1879, Thomas Edison’s light bulb relied on direct current, but such currents can't efficiently transmit power over long distances. Nikola Tesla introduced alternating current, which feature far fewer energy loses. Despite Edison’s attempts to discredit AC, Tesla proved its efficiency by lighting the 1893 Chicago World’s Fair.

Tesla's lack of business savvy and inability to commercialize led to his obscurity

For decades, despite pioneering technologies for large-scale electrical systems and telecommunications, Nikola Tesla had been forgotten to history. Rather than monetizing his work and becoming more well known, his inventor-first mentality saw him sell off lucrative patents to fund new experiments in the short term.

Nikola Tesla's original laboratory was recognized as a historical site in 2018

Beginning in 1901, the Wardenclyffe Tower was built on Long Island, New York to transmit electrical power through Earth's atmosphere. The project was abandoned before becoming operational due to limited funding, and was demolished for scrap in 1917 to help pay off Tesla's debts.

Tesla's first successful AC prototype used a metal shoe polish tin for a rotor

After leaving his position working with Thomas Edison, Tesla partnered with George Westinghouse to promote alternating current systems as a more viable, scalable solution to electricity transmission.

When Tesla died in 1943, the FBI seized his property for national security

Although Nikola Tesla had become increasingly eccentric in his later years, the US government wanted to ensure plans for a possible secret weapon didn’t fall into enemy hands during World War II.

Read about the nine depictions of Nikola Tesla in media through 2020

Portrayals include comedic takes, like John C. Reilly's performance in Comedy Central's "Drunk History" series, and more serious interpretations, like Nicholas Hoult's performance in Alfonso Gomez-Rejon’s historical drama, "The Current War."

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 quote by scientist Nikola Tesla

"The scientific man does not aim at an immediate result ... His duty is to lay the foundation for those who are to come, and point the way."

The world's first geothermal power plant was built in 1913 in Devil's Valley

In Tuscany, Italy, Prince Piero Ginori-Conti of Trevignano established the plant nine years after creating a generator that powered five light bulbs using steam vents in the area. Within three years, a second plant was built with two generators, each with 10 times the energy output of the first.

Thomas Edison inadvertently spurred the film industry's move to Hollywood

The inventor's patent on the motion picture camera included several stipulations that required independent movie studios to work with Edison's Motion Picture Patents Co., making the East Coast undesirable for aspiring filmmakers.

Nearly 40% of American cars were electric in 1899

They were most common in cities, where battery swap stations allowed drivers to "refuel" their vehicles reliably. Innovations in combustion engines caused electric cars to lose ground until environmental policies and advances in battery technology revitalized interest.

Before Silicon Valley, the American innovation hub was New Jersey

Today, Silicon Valley is known for its dominance in the tech world. But before it rose to prominence, New Jersey was the country's innovation hub. From Thomas Edison's light bulb to the transistor, New Jersey was considered the nation's leader in technology.

A dispute about the origin of twitching frog legs led to the invention of the first battery

Experiments by Luigi Galvani on exposed frog leg nerves showed activity when they were hung from iron railings and brass hooks, suggesting the existence of "animal electricity" that discharged when connected to metals. Alessandro Volta's voltaic pile, which stacked metals with an inorganic electrolyte, showed that electricity originates from chemical reactions.

Born to a well-off family in South Africa, Elon Musk left for Canada in 1989 before heading to the US

Musk was bullied as a child in South Africa, and even recalled being punched in the face, per a recent Walter Isaacson biography on the entrepreneur.

The first US patent for a roller coaster was issued in January 1884

Despite their Russian origins, roller coasters are often associated with the US. This is in part thanks to a businessman and inventor named LaMarcus Thompson, who revolutionized the amusement industry in the US beginning with the Gravity Pleasure Switchback Railway at Coney Island. He is now known as the "father of the American roller coaster."

Take a drone tour of a Tesla factory

The first of Tesla's large-scale European manufacturing plants for its electric vehicles was opened in Berlin in 2022. It—along with other facilities in Nevada, New York, Texas, and Shanghai—collectively manufactures solar panels, batteries, and other energy collection and storage products.

The organizer of CES originated as the Radio Manufacturers Association in the 1920s

This centennial page explores the Consumer Technology Association’s 100-year history, from its founding in 1924 shortly after the invention of the radio, to its leadership of CES Las Vegas. Read through the history of the wireless age and how it gave birth to a growing consumer electronics movement.

Thomas Cook invented modern tourism

In the mid-1800s, Cook took wealthy Britons on tours of Europe, Africa, the Middle East, and the US, often packaging together transportation, lodging, and food, effectively creating the modern travel agent. He also pioneered travel writing, with “Travellers Handbooks” offering tourists tips for visiting various countries.

The history of many kitchen appliances involves unexpected discoveries and applications, including wartime radar turned hamster defroster and replacing an 'ice king' with heat-stealing boxes.

Pizza is believed to have been invented in Naples

Flatbreads were eaten by ancient Egyptians, Romans, and Greeks, but historians trace pizza—flatbread with toppings, including present-day staples like tomatoes, cheese, garlic, oregano, and oil—back to 18th-century Naples, where the food was loved by its working poor, who appreciated a cheap, tasty meal. Naples formally became a part of Italy in 1861.
