The disputed inventor of the radio

Guglielmo Marconi overshadowed Nikola Tesla through commercialization

Despite Tesla envisioning wireless power and communication earlier, Marconi developed practical implementations of wireless communication, including transmitting the first transatlantic radio signal. The technology, which facilitated telegraphy critical for warships and navies, earned Marconi the 1909 Nobel Prize in physics.

J.P. Morgan provided Nikola Tesla with funding for the Wardenclyffe Tower

The structure was part of a project to transmit electricity and communication signals wirelessly across the globe. Shortly after construction began, Guglielmo Marconi beat Tesla to the punch and transmitted a trans-Atlantic signal, preventing Tesla from getting additional funding to finish his project.

In 1898, Nikola Tesla wowed a crowd by controlling a boat with no visible connection

Some onlookers thought it was a trick, such a a monkey being inside the boat, rather than mind control or some other metaphysical phenomenon. In reality, Tesla was pioneering radio waves, proving wireless control was possible.

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.

The Tesla coil was the first system to wireless transmit electricity

Developed in 1891, the system effectively consists of two open electric circuits with a gap of air between them. When a high enough voltage is built up, air becomes a conductor and sparks of electricity are generated.

Credit for inventing the laser was fought over for nearly three decades

Although Theodore Maiman built the first working laser in 1960, Gordon Gould coined the term earlier. Charles Townes and Arthur Schawlow of Bell Labs filed a patent after Gould came up with the idea and name, but before Gould filed his patent.

Marie Curie's daughter Irene discovered artificial radioactivity

The discovery continued the family's Nobel legacy by winning the Nobel Prize in Chemistry in 1935 alongside her husband, Frederic Joliot. Their work laid the foundation for the use of radioisotopes in medicine, agriculture, and energy production.

When a radio company was the biggest tech stock around

The Radio Corporation of America was the biggest stock during the 1920s. Originally called Marconi Wireless, the company transformed radio technology. The company pioneered broadcasting, created NBC, and became a tech giant. After remarkable growth and challenges, RCA was acquired by General Electric in 1986, marking the end of its 67-year independent existence.

Before the invention of transistors, vacuum tubes made radio possible

Discovered by Thomas Edison, vacuum tubes allow electrical currents to travel through empty space. Later modified into a diode—keeping current flowing in only one direction—vacuum tubes allowed electronics to turn alternating current into direct current.

Many scholars consider the first commercial radio broadcast to be during the 1920 presidential election

On Nov. 2, Pittsburgh, Pennsylvania, station KDKA broadcast the results of the presidential election. Leo Rosenberg delivered the news that Warren Harding had won in a landslide to an audience of around 100 people.

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.

Why Edwin Armstrong developed FM radio

AM radio was popular but prone to interference and static, which could be frustrating for listeners. In 1933, Armstrong, a Columbia University professor, discovered that a clearer signal could be broadcast by revising how it was captured.

The discovery of neutron stars by Jocelyn Bell Burnell, who was not awarded the corresponding Nobel Prize

During her doctoral program in radio astronomy at Cambridge University, Bell Burnell's first two observations of a neutron star were initially dismissed as interference by Antony Hewish, her advisor. He and Martin Ryle, head of the research group, were jointly awarded the Nobel Prize in physics, the first awarded for astronomical research.

Alfred Nobel invented dynamite and later used his fortune to fund peace prizes

Nobel stabilized dangerous nitroglycerin to create dynamite, revolutionizing construction and mining in the 19th century. Despite his success with explosives, he was deeply disturbed by their destructive potential and redirected his legacy toward rewarding human progress.

During his 'miraculous year,' Einstein published four groundbreaking papers

The 1905 "annus mirabilis" papers explained the photoelectric effect, Brownian motion, the absolutism of the speed of light, and mass-energy equivalence, revolutionizing scientists' understandings of space, time, mass, and energy. For the discovery of the photoelectric effect, Einstein won the 1921 Nobel Prize in Physics.

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."

Computer pioneer Alan Turing was also an elite runner

Alan Turing is credited with helping to found modern computer science, in addition to cracking the Nazi code known as Enigma. Beyond these world-historical achievements, the British mathematician also nearly represented his country in the Olympics in the marathon, running just 11 minutes slower than the eventual gold recipient at the 1948 games. Read more on this lesser-known aspect of the man here.

Since 1901, about 1,000 individuals have been awarded Nobel Prizes. The Nobel Foundation provides biographies of every winner and concise descriptions of their accomplishments, as well as interviews and videos with more recent winners.

Some claim the Wrights weren’t first in flight

Their scientific and engineering achievements aside, the Wrights’ claim to be first in flight is debated—and rejected—by some in the industry. Other early pioneers like Gustave Whitehead or Alberto Santos-Damonto are said to deserve the title.

Pigeons were thought to be the cause of what would be evidence of the Big Bang

In 1964, Arno Penzias and Robert Wilson accidentally detected the CMB while trying to eliminate persistent static from their radio antenna. The pair initially blamed the signal on pigeon droppings inside their antenna—cleaning it didn’t help, but it did win them a Nobel Prize.

Radio waves are used in broadcasting, weather radar, telecommunications, and GPS

Its ability to bend around obstacles and reflect off the ionosphere—an electrified layer of Earth's upper atmosphere—allows this type of light to travel long distances without damaging living things due to its low energy. MRI scanners, WiFi, and Bluetooth technologies are also applications of this form of light.

The discovery of insulin led to a controversial Nobel Prize in 1923

For centuries, Type 1 diabetes was fatal. The 1920s "discovery" of insulin netted two of its creators—Frederick Banting and his boss, John Macleod—a Nobel prize. Separately, the German doctor Georg Zuelzer synthesized an effective version of the life-saving drug years earlier but was interrupted by World War I.
