Jeanne Villepreux-Power began her adult life as a dressmaker, but rose to become one of the preeminent marine biologists of her day.

If you've ever been captivated by colorful fish and sea creatures darting around an aquarium, you can thank 19th century French scientist Jeanne Villepreux-Power! Villepreux-Power began her adult life as a dressmaker, but rose to become one of the preeminent marine biologists of her day. Her invention of a glass box for holding and observing marine specimens — the first recognizable glass aquarium — earned her the title "Mother of Aquariophily" from British biologist Richard Owen. "[She] was not content with purely descriptive studies of dead specimens," French scientist Claude Arnal wrote in a tribute to her. "She was excited by life and its mysteries."

Betty Reid Soskin began her career as a ranger at the age 85 at the Rosie the Riveter WWII Home Front National Historical Park.

Betty Reid Soskin, America's oldest National Park Service ranger, celebrated her 102nd birthday today! Soskin began her career as a ranger at age 85 at the Rosie the Riveter WWII Home Front National Historical Park in California — a park that she had helped plan in its early stages years earlier. Prior to her retirement in 2022 at the age of 100, Soskin gave a popular tour called “Untold Stories and Lost Conversations" during which she gave a tour of the park, shared her personal WWII story, and encouraged others to contribute their own stories to the park's collection of oral histories.

Emily Warren Roebling became the first female field engineer in history as the "surrogate chief engineer" of one of the greatest architectural projects of the 19th century, the construction of the Brooklyn Bridge.

When the Brooklyn Bridge was completed after fourteen years of construction in 1883, Emily Warren Roebling — the "woman who saved the Brooklyn Bridge" — was the first to cross it by carriage, carrying a live rooster in her lap as a sign of victory. Early in its construction, Roebling's husband, Washington, the chief engineer in charge of the bridge’s construction, became severely debilitated and bedridden due to decompression sickness. Emily Roebling stepped in and, for over a decade, oversaw the completion of one of the greatest architectural feats of the 19th century — making history by becoming the first female field engineer in the process. "I don’t think that the Brooklyn Bridge would be standing were it not for her," asserts Erica Wagner, the author a biography about Washington Roebling. "She was absolutely integral."

For her discovery of artificial radioactivity, Irène Joliot-Curie was awarded the Nobel Prize in Chemistry in 1935, just as her mother, Marie Curie, had in 1911.

Radiation can be dangerous, even deadly — but it has also saved millions of lives thanks to Irène Joliot-Curie's discovery of artificial radiation! Joliot-Curie, the daughter of Marie Curie, the first woman ever to win a Nobel Prize, carried on her mother's legacy of scientific study. Joliot-Curie's groundbreaking research allowed scientists to produce 'designer' radioactive elements quickly and easily, making them widely available for use in research and medical treatment for the first time. This discovery won Joliot-Curie and her husband, Frédéric Joliot-Curie, the Nobel Prize for Chemistry in 1935, cementing her place in scientific history — and making the Curies the family with the most Nobel laureates to date.  Continue reading → Continue reading

At six years old, Ruby Bridges famously became the first Black child to desegregate an all-White elementary school in the South.

The moment has been immortalized in a Norman Rockwell painting with the apt title The Problem We All Live With: a little African American girl walks to school, surrounded by a team of U.S. Marshals, with racist graffiti and thrown garbage ornamenting the wall behind her. Ruby Bridges was only 6 years old in 1960 when the first grader arrived for her first day of school at  William Frantz Elementary School in New Orleans — and was met by a vicious mob. The courageous girl would spend a year alone in the classroom, since other children had been removed by their parents due to her presence. But today, the 68-year-old Bridges says that those difficult days were worth it: "I now know that experience comes to us for a purpose, and if we follow the guidance of the spirit within us, we will probably find that the purpose is a good one."

Our top picks of books for children and teens about the girls and women who fought for workers' rights.

For many children today, Labor Day is just a holiday marking the end of the summer; what they often don't know is that this special day commemorates the history of the struggle for workers' rights — one in which girls and women played important and too often forgotten roles. Held on the first Monday in September in the U.S. and Canada, Labor Day celebrates the contributions of workers and remembers the hardships they endured in their fight for justice.

The Nazis had a 5 million-franc bounty on the head of the spy known as the "White Mouse."

In 1943, Nazi authorities were on the hunt for a spy they had nicknamed the "White Mouse" because of her ability to evade their capture, no matter what trap they set. The Gestapo had declared her their most wanted person, and placed a 5 million-franc bounty on her head. Their quarry was Nancy Wake, one of Britain's Special Operations Executive's most capable secret agents. Famous for her fearlessness, Wake would continue to evade her pursuers for the rest of the war, at one point even hurling herself from a train window to escape capture, and eventually become one of the Allies' most decorated servicewomen of World War II.

Katherine Johnson calculated -- by hand -- the flight trajectories for a number of historic missions, including the Apollo 11 flight to the Moon in 1969.

When President Barack Obama awarded the Presidential Medal of Freedom to Katherine Johnson in 2015, few people had even heard her name — but thanks to the smash success of the book Hidden Figures and its movie adaptation, this groundbreaking mathematician has become an inspiration for girls everywhere!

A Mighty Girl's top picks of picture books about trailblazing girls and women throughout history.

If you flip through a typical history book, you might think, as historian Gerda Lerner once wrote, that "ostensibly one-half the human race is doing everything significant and the other half doesn’t exist." Far too often, women's contributions have been neglected in history books and school curriculums — fortunately, there are growing numbers of wonderful books being published for young readers about girls and women who made their mark on history. And, there's no better time to share these stories and make sure that the next generation — girls and boys alike — appreciates the important and diverse roles that women have played in history!

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.
