Lost Women of Science
For every Marie Curie or Rosalind Franklin whose story has been told, hundreds of female scientists remain unknown to the public at large. In this series, we illuminate the lives and work of a diverse array of groundbreaking scientists who, because of time, place and gender, have gone largely unrecognized. Each season we focus on a different scientist, putting her narrative into context, explaining not just the science but also the social and historical conditions in which she lived and worked. We also bring these stories to the present, painting a full picture of how her work endures.

A Complicated Woman: Leona Zacharias
Scientist Leona Zacharias was a rare woman. She graduated from Barnard College in 1927 with a degree in biology, followed by a Ph.D. from Columbia University. But throughout her career she labored behind men with loftier titles who got the bulk of the credit. In the 1940s, when premature newborns were going blind after being born with perfectly healthy eyes, Dr. Zacharias was part of the team that worked to root out the cause.
In this inaugural episode of Lost Women of Science Shorts, host Katie Hafner visits the archives at M.I.T. and The Massachusetts Eye and Ear Infirmary in Boston to try to understand Dr. Zacharias’s role in rooting out the cause.For host Katie Hafner, it's personal: Leona Zacharias was her grandmother.

The Woman Who Knocked Science Sideways
We’re hard at work producing the next season of Lost Women of Science, but we wanted to bring you this special guest episode from Portraits, a podcast from the Smithsonian’s National Portrait Gallery. Dr. Chien-Shiung Wu was a towering figure in science whose parity experiment shattered our understanding of the physical world. She enjoyed rockstar status in China, met the pope, inspired an opera and even became a “Jeopardy!” question. But to Jada Yuan, she was grandma.
See the portraits discussed in the episode:

The Feminist Test We Keep Failing
There's a test that we at Lost Women of Science seem to fail again and again: the Finkbeiner Test. Named for the science writer, Ann Finkbeiner, the Finkbeiner Test is a checklist for writing profiles of female scientists without being sexist. It includes rules like not mentioning her husband’s job, or her childcare arrangements, or how she was the “first woman to…”—all rules we break regularly on this show. In this episode, Katie Hafner talks to Christie Aschwanden, the science writer who created the test, and Ann Finkbeiner, who inspired it, to find out how they came up with these rules, and to see if there might be hope yet for our series. She reports her findings to Carol Sutton Lewis, who has a whole other set of rules for telling these stories.

The First Lady of Engineering: Chapter 4
YY taught at Tennessee State University, a historically Black university, for 55 years. In this episode, we hear from YY’s colleagues, students and family members about who she was as an educator and how she’s remembered. We’ll also explore where HBCUs stand today – particularly, why they graduate so many successful Black scientists compared to other institutions, and their place in the future of science. Plus, a reimagining of YY’s accomplishments: what did it mean to be the first?

The First Lady of Engineering: Chapter 3
What is mechanical engineering? What was YY actually doing? This episode is about the work itself – specifically, the work Yvonne Young Clark did at NASA on the Saturn V rocket, and in designing the “moon rock box” for transporting lunar samples back to Earth. And we take a deep dive into the history of the American space program, the mechanics of a rocket, and how YY brought her troubleshooter’s mind to a problem that was plaguing some of the country’s top scientists.

The First Lady of Engineering: Chapter 2
When YY started college at Howard University as a mechanical engineering student, there were three things she swore she’d never do: marry a tall man, become a teacher, and work for the government. But love and life had other plans, and YY soon discovered the difficulty of entering private industry as one of the few Black women in her field. After success at RCA-Victor and Frankford Arsenal, YY moved back to the South, where Brown v. Board of Education had recently integrated public schools, prompting a violent backlash.

The First Lady of Engineering: Chapter 1
With a librarian mother and a physician father, YY was brought up in a supportive, educated, and prosperous Black enclave of Louisville, Kentucky. Her parents nurtured her knack for engineering. She got her start as a young child when she repaired the family toaster. An early introduction to a Black pilot group inspired her to fly planes, and she applied to the University of Louisville, where she hoped to study engineering and eventually aeronautics—until she learned her race disqualified her.

The First Lady of Engineering: Trailer
Yvonne Y. Clark, known as YY throughout her career, has also been nicknamed “The First Lady of Engineering,” because of her groundbreaking achievements as a Black female mechanical engineer. Season 3 of Lost Women of Science traces her trajectory, from her unconventional childhood interest in fixing appliances to civil rights breakthroughs in the segregated South; from her trailblazing role at historically Black colleges and universities to her work at NASA. What can YY teach us about what it means to be the first in a scientific field, especially as a Black woman in America?
