Necessity isn't the only mother of invention. Though it wasn't always easy to get patents or the credit they deserved, women are responsible for many items we use today.

1. THE PAPER BAG

America got a brand new paper bag when cotton mill worker Margaret Knight invented a machine to make them with a flat square bottom in 1868. (Paper bags originally looked more like envelopes.) A man named Charles Annan saw her design and tried to patent the idea first. Knight filed a lawsuit and won the patent fair and square in 1871.

2. KEVLAR

Lightweight, high-tensile Kevlar—five times stronger than steel—will take a bullet for you. DuPont chemist Stephanie Kwolek accidentally invented it while trying to perfect a lighter fiber for car tires and earned a patent in 1966.

3. THE FOOT-PEDAL TRASH CAN

Lillian Gilbreth improved existing inventions with small, but ingenious, tweaks. In the early 1900s, she designed the shelves inside refrigerator doors, made the can opener easier to use, and tidied up cleaning with a foot pedal trash can. Gilbreth is most famous for her pioneering work in efficiency management and ergonomics with her husband, Frank. Two of their 12 children, Frank Jr. and Ernestine Gilbreth, humorously wrote about their home/work collaborations in the book Cheaper by the Dozen.

4. MONOPOLY

Elizabeth Magie created The Landlord's Game to spread the economic theory of Georgism—teaching players about the unfairness of land-grabbing, the disadvantages of renting, and the need for a single land value tax on owners. Fun stuff! Magie patented the board game in 1904 and self-published it in 1906. Nearly 30 years later, a man named Charles Darrow rejiggered the board design and message and sold it to Parker Brothers as Monopoly. The company bought Magie's patent for the original game for $500 and no royalties.

5. WINDSHIELD WIPERS

Drivers were skeptical when Mary Anderson invented the first manual windshield wipers in 1903. They thought it was safer to drive with rain and snow obscuring the road than to pull a lever to clear it. (Another woman inventor, Charlotte Bridgwood, invented an automatic version with an electric roller in 1917. It didn't take off, either.) But by the time Anderson's patent expired in 1920, windshield wipers were cleaning up. Cadillac was the first to include them in every car model, and other companies soon followed.

6. DISPOSABLE DIAPERS

Marion Donovan didn't take all the mess out of diaper changing when she patented the waterproof "Boater" in 1951. But she changed parenting—and well, babies—forever. The waterproof diaper cover, originally made with a shower curtain, was first sold at Saks Fifth Avenue. Donovan sold the patent to the Keko Corporation for $1 million and then created an entirely disposable model a few years later. Pampers was born in 1961.

7. THE DISHWASHER

Patented in 1886, the first dishwasher combined high water pressure, a wheel, a boiler, and a wire rack like the ones still used for dish drying. Inventor Josephine Cochrane never used it herself, but it made life easier for her servants.

8. LIQUID PAPER

In the days before the delete key, secretary Bette Nesmith Graham secretly used white tempera paint to cover up her typing errors. She spent years perfecting the formula in her kitchen before patenting Liquid Paper in 1958. Gillette bought her company in 1979 for $47.5 million. And that's no typo.

9. ALPHABET BLOCKS

Children don't read books by anti-suffrage author Adeline D.T. Whitney these days—and that's probably for the better. But the wooden blocks she patented in 1882 still help them learn their ABCs.

10. THE APGAR SCORE

Life is a series of tests, starting with the Apgar, named after obstetrical anesthesiologist Dr. Virginia Apgar. In 1952, she began testing newborns one minute and five minutes after birth to determine if they needed immediate care. About 10 years later, the medical community made a backronym—an acronym designed to fit an existing word—to remember the criteria scored: Appearance, Pulse, Grimace, Activity, and Respiration.

11. MARINE SIGNAL FLARES

Communication between ships was once limited to colored flags, lanterns, and screaming things like "Thar she blows!" really loudly. Martha Coston didn't come up with the idea for signal flares all by herself. She found plans in a notebook that belonged to her late husband. The determined widow spent 10 years working with chemists and pyrotechnics experts to make the idea a reality. But she was only named administratrix in the 1859 patent—Mr. Coston got credited as the inventor.

12. THE CIRCULAR SAW

A weaver named Tabitha Babbitt was the first to suggest that lumber workers use a circular saw instead of the two-man pit saw that only cut when pulled forward. She made a prototype and attached it to her spinning wheel in 1813. Babbitt's Shaker community didn't approve of filing a patent, but they took full advantage of the invention.

13. RETRACTABLE DOG LEASH

New York City dog owner Mary A. Delaney patented the first retractable leading device in 1908. It attached to the collar, keeping pooches under control, while giving them some freedom to roam. Incidentally, someone named R.C. O'Connor patented the first child harness 11 years later. Coincidence? Maybe.

14. SUBMARINE TELESCOPE AND LAMP

It's difficult to find any in-depth information about early inventor Sarah Mather. Her combination telescope and lamp for submarines, patented in 1845, speaks for itself.

15. FOLDING CABINET BED

Sarah E. Goode's folding cabinet bed didn't just maximize space in small homes. In 1885, it made her the first African-American woman with a U.S. patent. The fully functional desk could be used by day and then folded down for a good night's sleep. The Murphy bed came along some 15 years later.

16. THE SOLAR HOUSE

Biophysicist Maria Telkes's place was in the house—the very first 100 percent solar house. In 1947, the Hungarian scientist invented the thermoelectric power generator to provide heat for Dover House, a wedge-shaped structure she conceived with architect Eleanor Raymond. Telkes used Glauber's salt, the sodium salt of sulfuric acid, to store heat in preparation for sunless days. Dover House survived nearly three Massachusetts winters before the system failed.

17. SCOTCHGARD

Apparently, it takes a stain to fight one. In 1952, 3M chemist Patsy Sherman was perplexed when some fluorochemical rubber spilled on a lab assistant's shoe and wouldn't come off. Without changing the color of the shoe, the stain repelled water, oil, and other liquids. Sherman and her co-inventor Samuel Smith called it Scotchgard. And the rest is ... preserving your couch.

18. INVISIBLE GLASS

Katharine Blodgett, General Electric's first female scientist, discovered a way to transfer thin monomolecular coatings to glass and metals in 1935. The result: glass that eliminated glare and distortion, which revolutionized cameras, microscopes, eyeglasses, and more.

19. COMPUTERS

Women in computer science have a role model in Grace Hopper. She and Howard Aiken designed Harvard's Mark I computer, a five-ton, room-sized machine in 1944. Hopper invented the compiler that translated written language into computer code and coined the terms "bug" and "debugging" when she had to remove moths from the device. In 1959, Hopper was part of the team that developed COBOL, one of the first modern programming languages.

8 Facts About David Bowie's 'Space Oddity'

On July 20, 1969, astronauts walked on the Moon for the first time. Just a few weeks earlier, another space-age event had rocked the world: David Bowie’s single “Space Oddity” hit airwaves. The song, whose lyrics tell the story of an astronaut’s doomed journey into space, helped propel the artist to icon status, and five decades later, it’s still one of his most popular works. 

1. "Space Oddity" was inspired by 2001: A Space Odyssey.

Many listeners assumed that "Space Oddity" was riffing on the Apollo 11 Moon landing of 1969, but it was actually inspired by a Stanley Kubrick film released a year earlier. Bowie watched 2001: A Space Odyssey multiple times when it premiered in theaters in 1968. “It was the sense of isolation I related to,” Bowie told Classic Rock in 2012. “I found the whole thing amazing. I was out of my gourd, very stoned when I went to see it—several times—and it was really a revelation to me. It got the song flowing.”

2. "Space Oddity" was also inspired by heartbreak.

The track was also partly inspired by the more universal experience of heartbreak. Bowie wrote the song after ending his relationship with actress Hermione Farthingale. The break inspired several songs, including “Letter to Hermione” and “Life on Mars,” and in “Space Oddity,” Bowie’s post-breakup loneliness and melancholy is especially apparent.

3. "Space Oddity" helped him sign a record deal.

In 1969, a few years into David Bowie’s career, the musician recorded a demo tape with plans to use it to land a deal with Mercury Records. That tape featured an early iteration of “Space Oddity,” and based on the demo, Mercury signed him for a one-album deal. But the song failed to win over one producer. Tony Visconti, who produced Bowie’s self-titled 1969 album, thought the song was a cheap attempt to cash in on the Apollo 11 mission, and he tapped someone else to produce that particular single.

4. The BBC played "Space Oddity" during the Moon landing.

"Space Oddity" was released on July 11, 1969—just five days before NASA launched Apollo 11. The song doesn’t exactly sound like promotional material for the mission. It ends on a somber note, with Major Tom "floating in a tin can" through space. But the timing and general subject matter were too perfect for the BBC to resist. The network played the track over footage of the Moon landing. Bowie later remarked upon the situation, saying, "Obviously, some BBC official said, 'Oh, right then, that space song, Major Tom, blah blah blah, that’ll be great. 'Um, but he gets stranded in space, sir.' Nobody had the heart to tell the producer that."

5. David Bowie recorded an Italian version of "Space Oddity."

The same year "Space Oddity" was released, a different version David Bowie recorded with Italian lyrics was played by radio stations in Italy. Instead of directly translating the English words, the Italian songwriter Mogul was hired to write new lyrics practically from scratch. "Ragazzo Solo, Ragazza Sola" ("Lonely Boy, Lonely Girl") is a straightforward love song, and Major Tom is never mentioned.

6. Major Tom appeared in future songs.

Major Tom, the fictional astronaut at the center of "Space Oddity," is one of the most iconic characters invented for a pop song. It took a decade for him to resurface in David Bowie’s discography. In his 1980 single "Ashes to Ashes," the artists presents a different version of the character, singing: "We know Major Tom's a junkie/Strung out in heaven's high/Hitting an all-time low." Bowie also references Major Tom in "Hallo Spaceboy" from the 1995 album Outside.

7. "Space Oddity" is featured in Chris Hadfield's ISS music video.

When choosing a song for the first music filmed in space, Canadian astronaut Chris Hadfield naturally went with David Bowie’s out-of-this-world anthem. The video above was recorded on the International Space Station in 2013, with Hadfield playing guitar and singing from space and other performers providing musical accompaniment from Earth. Some lyrics were tweaked for the cover. Hadfield mentions the "Soyuz hatch" of the capsule that would eventually shuttle him to Earth.

8. "Space Oddity" played on the Tesla that Elon Musk sent to space.

In 2018, Elon Musk used SpaceX's Falcon Heavy rocket to launch his Tesla Roadster into space. The car was decked out with pop culture Easter eggs—according to Musk, "Space Oddity" was playing over the car’s radio system during the historic journey. The dummy’s name, Starman, is the name of another space-themed song on Bowie's 1972 masterpiece The Rise and Fall of Ziggy Stardust and the Spiders from Mars.
