The Apollo 11 moon landing nearly ended in failure -- until Margaret Hamilton's flight software saved the day.

In this iconic photograph, pioneering computer scientist Margaret Hamilton stands next to the computer code that she and her team wrote to guide the Apollo spacecraft to the moon! Hamilton was the lead software designer for NASA’s Apollo program, and her forward thinking saved the 1969 Apollo 11 mission when the flight software she designed prevented a last-minute abort of the famous landing which brought the first humans to the Moon. Over the course of her career, Hamilton developed the concepts of asynchronous software, priority scheduling, and Human-in-the-loop decision capability, which became the foundation of modern software design. She also fought for programming to be given the respect it deserved, coining the term "software engineering" ; after all, as her work showed, software could make the difference between failure and a groundbreaking success.

Dr. Gerty Cori's groundbreaking work cracked the secrets of glucose, paving the way for treatments for diseases like diabetes.

The groundbreaking scientist Dr. Gerty Cori was the first woman to win a Nobel Prize in Medicine and the first American woman to win a Nobel Prize in a scientific field. She shared the Nobel with her husband and lifelong research partner, Carl. Although their experience and education was identical, it took thirteen years before she was finally promoted to the same rank as him at the university where they worked. Together, the Coris made numerous breakthroughs in medical research, including discoveries that paved the way for understanding and developing treatments for diabetes and other metabolic diseases. Despite the institutionalized sexism she faced throughout her career, Gerty's tremendous scientific mind could not be denied — and her work would change the field of biochemistry forever.

Mary Golda Ross spent over 30 years at Lockheed, much of it as a member of the top-secret Skunk Works program involved in cutting edge research during the early years of the space race.

When Mary Golda Ross, the first Native American aerospace engineer, began her career at the aerospace company Lockheed during World War II, women engineers were rare and most companies expected them to leave after the war was over to make room for returning men. Ross was such a phenomenal talent, however, that she not only stayed at Lockheed for over 30 years years, she became an integral member of the top-secret Skunk Works program involved in cutting edge research during the early years of the space race. As one of 40 engineers in Lockheed's Advanced Development Projects division, Ross was the only female engineer on the team and the only Native American. Her research was so secret that, even in 1994, she had to be coy with an interviewer about her work: "I was the pencil pusher, doing a lot of research," she said. "My state of the art tools were a slide rule and a Friden computer." Continue reading → Continue reading

Eliza Schuyler Hamilton outlived her famous husband Alexander by fifty years and went on to make her own mark on history.

Many people have heard of Elizabeth (Eliza) Schuyler Hamilton from the Lin-Manuel Miranda musical Hamilton about her husband Alexander, but most know little of the life and legacy of this influential Founding Mother. Eliza lived for 97 years — and outlived her famous husband by 50 years — during a tumultuous period that included the American Revolution and the establishment of American government and democracy, as well as personal dramas and tragedies, including the deaths of both her oldest son and her husband in duels. Despite it all, she went on to devote her life both to preserving Alexander’s legacy and to charitable causes, including the creation of the first private orphanage in New York City, even while her own family struggled with financial hardship. "I think anyone else would have been broken," says Ron Chernow, the author of Alexander Hamilton, the biography that inspired the hit musical. "Not only did she live, she prevailed."

Susie King Taylor's extraordinary life is captured in her memoir, one of the most detailed accounts ever written by a woman about life in a Civil War camp.

When Susie King Taylor was born in 1848, it was illegal to educate African Americans in Georgia but she learned to read and write thanks to a secret school. That gift of literacy would allow her to become a trailblazing teacher in her teens and, later, the first Black Army nurse during the U.S. Civil War; an experience she shared in her remarkable memoir about life in a Union camp. Today, more than a century later, her words show her fortitude and determination to make a contribution to the war effort. "I gave my service willingly for four years and three months without receiving a dollar," she wrote, adding that she was glad "to be allowed to go with the regiment, to care for the sick and afflicted comrades."

At the Seneca Falls Convention in 1848, the world's first women's rights convention, illustrious suffragists and feminists like Lucretia Mott and Elizabeth Cady Stanton took time to honor a groundbreaking scientist: Maria Mitchell, who had just become the first American and third woman in history to discover a comet! Mitchell would go on to become America's first professional female astronomer, and she used her newfound fame to advocate for scientific education for girls and women. "Does anyone suppose that any woman in all the ages has had a fair chance to show what she could do in science?" she asked. "Until able women have given their lives to investigation, it is idle to discuss the question of their capacity for original work." Or, as she wrote more pointedly in one of her journals, "better to be peering in the spectrograph than on the pattern of a dress." Continue reading → Continue reading

Stephanie Kwolek's invention of Kevlar has saved countless lives over the past 40 years.

Stephanie Kwolek's invention of Kevlar has saved countless lives over the past 50 years. Kevlar is a fiber five times stronger than steel that is now used in numerous products ranging from boots for firefighters to spacecraft — and most famously, in bulletproof vests. It's estimated that since Kevlar's introduction to body armor in the 1970s, the lives of over 3,000 police officers have been saved, as well as those of innumerable soldiers and others in conflict zones. On the day that the pioneering chemist passed away in 2014 at the age of 90, DuPont announced that the one-millionth protective vest made using Kwolek's lifesaving invention was sold.

Dr. Frances Kelsey resisted intense industry pressure to approve thalidomide; the drug was the cause of severe birth defects in over 10,000 infants in other countries.

When pharmacologist Dr. Frances Oldham Kelsey started working at the U.S. Food and Drug Administration (FDA) in 1960, one of the first files to cross her desk was an approval request for thalidomide. The drug had already been prescribed widely in Europe and other countries as a treatment for morning sickness in pregnant women, but Kelsey wasn't convinced it was safe. Her refusal to approve the drug, despite intense pressure from its manufacturer, likely saved tens of thousands of babies in America from devastating birth defects. "Representatives for the company thought I was crazy because it was such a popular drug in Europe, and they were losing money by my pigheadedness," asserted Kelsey in a later interview. "I held my ground. I just wouldn't approve it." Continue reading → Continue reading

Among hundreds of men, trailblazing NASA Engineer JoAnn Morgan was the sole woman present in the locked control room.

A famous photo shows the control room at Kennedy Space Center on the day of the historic Apollo 11 launch packed with hundreds of men in white shirts and skinny black ties — and, among them, a single woman sits at a console. As Apollo 11 began its flight to the moon on July 16, 1969, 28-year-old instrumentation controller JoAnn Hardin Morgan became the first woman ever permitted in the launch firing room, which is locked down in advance of a space flight. Morgan, who was the first female engineer at NASA's Kennedy Space Center, would go on to have a 40-year-long career at NASA. While she encountered challenges along the way, including being "the only woman there for a long time" and spending the first 15 years working "in a building were there wasn't a ladies rest room," Morgan says that "I had such a passion that overrode anything else, the lonely moments, the little bits of negative. They were like a mosquito bite. You just swat it and push on." Continue reading → Continue reading

Pioneering neuroscientist Brenda Milner, one of the founders of cognitive neuroscience, says that at 105, she's "still nosy."

If you go to the Department of Neurology and Neurosurgery at McGill University in Montreal, Canada, you might catch a glimpse of 105-year-old Dr. Brenda Milner — a pioneering neuroscientist who's still breaking new ground in her 70-year long career as a brain researcher! The eminent British-born scientist revolutionized brain science as a newly minted PhD in the 1950s. Today, she is best known for discovering where memory formation occurs in the brain and is widely recognized as one of the founders of cognitive neuroscience. Her research to better understand the inner workings of the human brain continues today, although she says that people often think she must be emerita because of her advanced age. "Well, not at all," she asserts. "I’m still nosy, you know, curious.” Continue reading → Continue reading
