Lost Women of Science

In this episode of Lost Women of Science Conversations, host Carol Sutton Lewis speaks with science writer Hanne Strager about her biography of Inge Lehmann, the pioneering Danish seismologist who discovered that Earth has a solid inner core.. 
Largely unknown outside scientific circles, Lehmann fundamentally transformed our understanding of what lies at the heart of our planet. She did this in 1936 by identifying anomalies in earthquake waves that others had overlooked. At the time, scientists believed Earth’s core was entirely liquid. Lehmann proposed instead that a solid inner core lay hidden within it — a groundbreaking insight that reshaped geophysics.
In revisiting Lehmann’s story, Strager highlights that Lehmann’s legacy is one of resilience and perseverance — proof that early setbacks do not define a life, and that brilliance can flourish, even later in life.

This bonus episode is a co-production with Distillations, a podcast produced by the Science History Institute.
Agnes Pockels did pioneering work in surface science. Her invention, the Pockels Trough, became the basis for an instrument that helped Katherine Burr Blodgett and Irving Langmuir make discoveries in material science that quietly shape our everyday world. 
But the way we talk about Agnes’s life and work often falls back on familiar tropes about women’s domestic roles, assumptions about how science gets done, and what it looked like to do science as a woman in the 19th century. 
 Agnes's story invites us to rethink how we define success for scientists. Is our definition too narrow? And what might we gain if we crack it open a bit wider?

How is a legacy preserved, and how is someone forgotten? Determined to make a final name for himself, Irving Langmuir ventures into science that even he might classify as pathological wishful thinking, while Katharine continues her work as the diligent experimenter. But her contributions faded from both the company’s and the public’s memory. We go to visit her, to say good-bye – and we look at the wisdom she imparted to the next generation of ​​inquiring minds.

Katharine’s relatives lead the production team to a collection of papers and artifacts stored in a New England storage unit, revealing an inner struggle she kept carefully out of sight – even as she was making history in the laboratory.

The 1930s prove to be an exceptional decade for research at The General Electric Company. Katharine Burr Blodgett works closely alongside her boss, Irving Langmuir who, in 1932, wins the Nobel Prize for Chemistry. In 1938, Katharine’s meticulous experiments with thin film coatings on solid surfaces lead to her most important breakthrough: non-reflecting glass. The General Electric Company’s public relations machine kicks into high gear. Katharine becomes an overnight sensation, both in the scientific community and in the press, which dub her discovery “invisible glass.” The assistant to the Nobel Prize winner, long invisible herself, takes center stage.
