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.

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.

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?

Carol Sutton Lewis, host of the podcast Ground Control Parenting, has long been interested in Black history. This season, she’s joining Lost Women of Science as a cohost to help tell the story of the mechanical engineer, Yvonne Young Clark. Known as Professor Clark to her students and YY to her engineering colleagues, YY’s career spanned academia and industry. She was a dedicated STEM educator and a champion of historically Black colleges and universities. Alongside cohost Katie Hafner, Carol will trace YY’s life and work through fascinating chapters of Black history, from the promises of Reconstruction to integration efforts at NASA.

We saw the story over and over again: computer programmer Klára Dán von Neumann was a pioneer in weather forecasting. But when we talked to Thomas Haigh, a historian who studies Klári’s work, he said he’s found absolutely no evidence of this. How did this weather myth start? We set out to answer that question, and in the process, we asked this: Why is it so tempting to credit the wrong person, even when that false credit is given with the best of intentions? Note: we’d like to acknowledge the operators of the ENIAC who ran the 1950 weather simulation, Homé McAllister and Clyde Hauff.

After Johnny’s death, Klári becomes the keeper of his legacy. It’s an exhausting, full-time commitment that takes her out of the computing world for good. She marries her fourth husband, a physicist, and moves to a Southern California beach town. She resolves to settle down, and starts writing a memoir. We discuss her legacy in computing and beyond, and the current state of gender and programming. Note: this episode includes content that could be upsetting. We’ll be talking about depression and self-harm. Access a transcript of the episode here.

After World War II, tensions build between the Soviet Union and the U.S. Scientists at Los Alamos continue developing nuclear weapons, helped by the recently-reconfigured ENIAC. Using a statistical method called Monte Carlo, they optimize nuclear weapons through computer simulations. In these simulations, physics is neither purely experimental nor theoretical–it’s both, creating what historian Peter Galison calls a “netherland…at once nowhere and everywhere.” And Klári finds herself immersed in this sort of netherworld, turning nuclear physics into code.

When John von Neumann runs into fellow mathematician Herman Goldstine at a train station, Goldstine clues him into a new powerful computer called the ENIAC that is being constructed to help with the war effort, and Johnny immediately grasps the machine’s enormous potential. Though the computer is not completed in time to be useful in the second world war, it finds new purpose in the war’s aftermath. Soon, Klári von Neumann is enlisted to instruct the machine what to do, and in doing so, becomes one of the first coders. This episode takes a deep dive into the workings of the ENIAC and the origins of computing in the 1940s.

With John von Neumann absorbed in work, Klári struggles to find a niche in her new suburban home while dealing with devastating losses. A new chapter opens for Klári when the U.S. finally enters the war and women are called into the workforce.

To understand how Klára Dán von Neumann arrived at computer programming, we need to first understand where she came from. Born in Budapest to a wealthy Jewish family, Klári grew up surrounded by artists, playwrights, and intellectuals. Her first marriage, to an inveterate gambler, took her on a tour of Europe’s casinos, and in one of them, she had a chance encounter with the famous mathematician, John von Neumann.
