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.

The Extraordinary Life and Tragic Death of Evangelina Rodríguez Perozo
In the 1880s, a small Afro-Dominican girl spent her days selling sweets on the streets of San Pedro de Macorís, a bustling port town in the Dominican Republic. Born out of wedlock and abandoned by her parents, her horizons seemed narrow — in this deeply stratified society, few people ever broke free from the life they were born into.But Andrea Evangelina Rodríguez Perozo had something that made people take notice. Two influential brothers, both poets and intellectuals, recognized a brilliant mind and a tenacious spirit. With the brothers’ support, Evangelina went on to chart a path that was unheard of for any Dominican woman at that time: she became her country’s first female doctor.In this five-part season, we will follow Evangelina as she studies medicine, first in her home country, then in Paris, where she learns new medical techniques in the emerging field of gynecology and encounters radical ideas about women’s health: ideas that she hopes will transform her society back in the Dominican Republic. Little does she think her new approaches to women’s health will eventually lead to her tragic downfall. Evangelina Rodríguez’s contributions as a reformer and pioneer in public health were all but erased by the dictator whose regime hounds her to death. Here, we piece together her life and her legacy.

Lost Women of Science Conversations: Lady Tan's Circle of Women
Lisa See’s novel Lady Tan’s Circle of Women is inspired by a medical textbook published in 1511 by an eminent female doctor, Tan Yunxian. In this episode, we talk to See about the origin of her novel, and to Lorraine Wilcox, the scholar who translated the original Chinese text, about what the practice of medicine was like for a female doctor during the Ming Dynasty. Tan Yunxian was almost lost to history, but the chronicle of her cases was reprinted by a great nephew and, amazingly, one copy survived through the centuries. Through serendipitous scholarly connections, Wilcox translated it and See used that translation as the inspiration for her novel.

Who Discovered the Cause of Down Syndrome ? Episode Two
In 1960 Marthe Gautier left the lab where she had discovered the genetic cause of Down syndrome, and went on to have a successful career as a pediatric cardiologist. For decades, she remained silent as her former colleague Jérôme Lejeune continued to take credit for this pioneering discovery, and history wrote her out of the story. Until 2009. On the 50th anniversary of the paper that announced the discovery of trisomy 21, she decided to set the record straight. The process of changing history did not always go smoothly. In 2014, at the age of 88, she was set to give a talk and receive a medal at a conference, but the event was canceled hours in advance, and she was given the medal privately the next day. Finally, toward the end of her life, Gautier got the recognition she deserved. Before she died in 2022, she was also decorated by the French government for her contributions to science.

Margarethe Hilferding, Sigmund Freud, and the Conspiracy of Silence
In honor of International Holocaust Remembrance Day, we are telling the story of Margarethe Hilferding, a pioneering psychoanalyst and physician from Vienna who was murdered in a Nazi concentration camp in 1942. She was the first woman to earn a medical degree at the University of Vienna and the first woman to join Sigmund Freud’s Vienna Psychoanalytic Society. In her paper On the Basis of Mother Love, presented to the society in 1911, she argued that the maternal instinct is not innate but can develop after birth, a theory Freud and the rest of her male colleagues rejected. Margarethe soon left the society and devoted much of her life to treating women in working class neighborhoods and advocating for their reproductive health. Her theory of maternal instinct remains controversial even today.

Best Of: Flora Patterson, the Woman who Kept Devastating Blights from U.S. Shores
At this festive time of year, when many people are bringing trees into their homes to decorate for the holidays, we are going back to our story of a pioneering scientist who made it her mission to ensure that plants traveling across borders did not carry any diseases. It was in 1909, that the Mayor of Tokyo sent a gift of 2,000 prized cherry trees to Washington, D.C. But the iconic blossoms enjoyed each spring along the Tidal Basin are not from those trees. That’s because Flora Patterson, who was the Mycologist in Charge at the USDA, recognized the original saplings were infected, and the shipment was burned on the National Mall. In this episode, we explore Patterson’s lasting impact on the field of mycology, starting with a blight that killed off the American chestnut trees, and how she helped make the USDA’s National Fungus Collection the largest in the world.

Lost Women of Science Conversations - Brave the Wild River
Two female botanists – Elzada Clover and Lois Jotter – made headlines for riding the rapids of the Colorado River in 1938 in an effort to document the Grand Canyon’s plant life. In Brave the Wild River: The Untold Story of Two Women Who Mapped the Botany of the Grand Canyon, author Melissa L. Sevigny retraces their journey and shows how the ambitious river expedition, one that many believed impossible for women, changed not only Clover and Jotter but also our understanding of botany in this remote corner of the American West.

Lost Women of the Manhattan Project: Carolyn Beatrice Parker
Carolyn Beatrice Parker came from a family of doctors and academics and worked during World War II as a physicist on the Dayton Project, a critical part of the Manhattan Project tasked with producing polonium. (Polonium is a radioactive metal that was used in the production of early nuclear weapons.) After the war, Parker continued her research and her studies at the Massachusetts Institute of Technology, but she died of leukemia at age 48 before she was able to defend her PhD thesis. Decades later, during the height of the Black Lives Matter protests, citizens in her hometown of Gainesville, Florida voted to rename an elementary school in her honor. November 18th would have been her 107th birthday.

Lost Women of Science Conversations: Attention is Discovery
Anna Von Mertens' thoughtful new exploration of Henrietta Swan Leavitt's life describes and illuminates Leavitt's decades-long study of stars, including the groundbreaking system she developed for measuring vast distances within our universe simply by looking at photographic plates. Leavitt studied hundreds of thousands of stars captured on the glass plates at the Harvard College Observatory, where she worked as a human computer from the turn of the 20th century until her death in 1921. Von Mertens explores her life, the women she worked alongside, and her discoveries, weaving biography, science, and visual imagery into a rich tapestry that deepens our understanding of the universe and the power of focused, methodical attention.
