Marie Curie pioneered radioactivity research, for which she won two Nobel Prizes

Marie Curie's research in radioactivity made her the first woman to win a Nobel Prize

Overcoming social and academic barriers, Curie's realization that radiation resulted from an intrinsic property of atoms reframed scientific understanding of the phenomenon. Her subsequent work in discovering two new elements—polonium and radium—earned her a second Nobel Prize.

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.

Marie Curie's work with radioactive materials left traces on her furniture and notes

Some of Marie Curie's family heirlooms were radioactive and destroyed. Marie and Pierre Curie are entombed in lead coffins to block radiation.

Marie Curie developed and trained women to operate mobile X-ray units in World War I

The “petites Curies” allowed medical professionals to identify the severity of wounds without transporting soldiers to medical facilities, expediting treatment and saving lives. The efforts of Curie and other women led to expansions in their rights after the war.

Pierre Curie's knowledge of electromagnetism helped decipher radioactivity

Alongside his brother, he studied electric fields in crystals and the magnetic properties of substances, which required the construction of delicate electrometers. He would use this apparatus with Marie Curie to measure radioactive emissions and the presence of undiscovered radioactive elements.

As of 2025, only five people have won two Nobel Prizes

The story of the Radium Girls, who exposed the dangers of radioactive paint

After radium was discovered in 1898, companies began using radium-based paints on watch and clock dials to create a glow-in-the-dark effect. Women who worked to apply the paint were encouraged to use their lips and tongues to help create the fine point needed to draw small numbers, unknowingly poisoning themselves.

The disputed inventor of the radio

Guglielmo Marconi was awarded the 1909 Nobel Prize in physics for inventing the wireless telegraph, which used radio waves to transmit Morse code. Nikola Tesla, however, was experimenting with radio waves in the 1890s, though much of his work was destroyed in a 1895 fire.

Radioactivity was accidentally discovered when uranium left marks on photographic plates

In 1896, Henri Becquerel had been exploring phosphorescence—the emission of light of one color after an object is exposed to another color. He expected these emissions to come from objects exposed to sunlight, but he observed emissions after an overcast day.

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

Despite the rules, a Nobel Prize in medicine has been awarded posthumously

Ralph Steinman, whose work revealed how dendritic cells activate immune responses, passed away just days before being named a Nobel laureate. Although Nobel Prizes cannot be awarded posthumously, the committee made an exception because they believed he was alive at the time of the decision.

Beyond DNA, Franklin's legacy extends into modern virology and steel production

Her research helped improve fuel efficiency, wartime protective equipment, and foundational knowledge in molecular biology.

Robert Koch won the Nobel for his tuberculosis work, but he also pioneered cholera research

Koch was one of the first scientists to isolate the bacterium that causes cholera while investigating an outbreak in Egypt in 1883. He went on to advise about rules to control cholera outbreaks, which formed the basis of the disease control approaches and water hygiene techniques still used today.

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.

The story of Marie Nyswander, the woman who co-discovered methadone maintenance

Methadone, an opioid with distinct effects from heroin, revolutionized heroin addiction in the 1960s. Marie Nyswander was a psychoanalyst who helped discover the treatment process which is still in use today. Here's a podcast episode examining her life and role in the field of addiction treatment.

How spoiled meat helped uncover a bacterium that can survive the vacuum of space

When a can of ground beef and pork spoiled despite attempts to sterilize it with gamma radiation, researcher Arthur Anderson isolated the bacteria in the food and discovered Deinococcus radiodurans. The polyextremophile has since been found on the walls of nuclear reactors and overcomes radiation damage through highly optimized DNA repair mechanisms.

Roosevelt joined the NAACP and campaigned for anti-lynching laws—even receiving a $25K bounty from the KKK

Eleanor Roosevelt joined the NAACP board, lobbied for a federal anti-lynching law, and pushed to integrate the Army Nurse Corps—often going beyond the support her husband was willing to give to racial justice efforts. Her advocacy made her a target: The Ku Klux Klan placed a $25,000 bounty on her head.

President Barack Obama compared Grace Hopper to the Wright Brothers

When posthumously awarding Hopper with the Presidential Medal of Freedom—the nation's highest civilian honor—on Nov. 22, 2016, the former president remarked, "If Wright is flight, and Edison is light, then Hopper is code. [...] From cell phones to [US] Cyber Command, we can thank Grace Hopper for opening programming to millions more people."

The accidental birth of radio astronomy and the benefits of a moon-based telescope

Detecting radio waves from distant celestial objects is complicated by noise from solar wind, which the nighttime side of the moon is shielded from. If lunar temperature extremes can be overcome, the environment may serve as an optimal future home for radio astronomy, a field that began in 1928 when a 30-meter-long directional antenna, mostly out of brass and wood, picked up signals from the Sagittarius constellation.

Astatine-211 is a radioisotope that can be used for therapeutic cancer treatment

How Lyndon Johnson created public radio

The Public Broadcasting Act of 1967, part of the president's Great Society plan, established the Corporation for Public Broadcasting, which later led to the incorporation of National Public Radio. Originally, the bill was intended solely to establish public television; before Johnson signed the act, slips of paper reading "and radio" were literally Scotch-taped next to each mention of "television."

Jean Carroll was one of the first women to make a name in stand-up comedy
