It’s the early 1960s and the German pharmaceutical market is booming. A sedative called Contergan is one of the bestselling drugs. Contergan’s active ingredient is thalidomide and it is touted as a wonder drug, a non-addictive sedative safer than barbiturates. In the U.S., the drug is called Kevadon, and its distributor is impatient to get the drug on the market. But Dr. Frances Kelsey, a medical examiner at the U.S. Food and Drug Administration, is stalling the approval of Kevadon. She wants more information from the manufacturer to prove it is safe. Meanwhile, doctors in Scotland and Australia are beginning to suspect thalidomide might, in fact, be very toxic. And in Germany, reports are beginning to emerge of a mysterious epidemic of babies born with missing limbs and other serious medical conditions, but doctors have no idea what's causing it.

In this first chapter of a new five-part season we meet Dr. Frances Oldham Kelsey, a physician and pharmacologist who joined the U.S. Food and Drug Administration as a medical reviewer in 1960. Before the year is out, Dr. Kelsey finds herself standing up to big pharma.

It’s September 1960 and a thick New Drug Application lands on Dr. Kelsey’s desk. The drug has already been on the market in Europe for three years and Dr. Kelsey’s supervisors expect her to rubber stamp the application. The drug is called Kevadon. Active ingredient: thalidomide. And to Frances Kelsey’s keen eye, something looks off.

In the 1950s, a German drug company developed a new sedative that was supposed to be 100% safe: thalidomide. So safe, in fact, it was promoted to women as a treatment for morning sickness. It quickly became a bestseller. But in the early 1960s, shocking news started coming out of Europe. Thousands of babies were being born with shortened arms and legs, heart defects, and other serious problems. Many died.

In the United States things were different, thanks to one principled, strong-minded skeptic who joined the Federal Drug Administration in 1960 as a medical reviewer. One of her first assignments was to review the approval application of that very wonder drug, thalidomide. But the application was, to her mind, flawed.

Dr. Frances Oldham Kelsey was a physician, a pharmacologist, and a nitpicker who refused to be intimidated by big pharma.

Starting in September, a new five-part series from Lost Women of Science: The Devil in the Details, the story of Frances Oldham Kelsey, The Doctor Who Said No To Thalidomide.

In the 1920s, when newspapers and magazines started to showcase stories about science, many of the early science journalists were women, working alongside their male colleagues despite less pay and outright misogyny. They were often single or divorced and, as Marcel Chotkowski LaFollette explains, writing for their lives. From Emma Reh, who traveled to Mexico to get a divorce and ended up trekking to archeological digs on horseback, to Jane Stafford, who took on taboo topics like sex and sexually transmitted diseases, they started a tradition of explaining science to non-scientists, accurately and with flair.

By the second half of the 20th century, physicists were on a mission to find the ultimate building blocks of the universe. What you get when you zoom in all the way to the tiniest bits that can’t be broken down anymore. They had a kind of treasure map, a theory describing these building blocks and where we might find them. But to actually find them, physicists needed to recreate the blistering-hot conditions of the early universe, when many of these particles last existed. That’s why, in the mid-1970s, a major national laboratory entrusted Helen Edwards with a huge task: to oversee the design and construction of the most powerful particle accelerator in the world, the first of a new generation of particle colliders built to uncover the inner workings of the universe.

Dr. Jess Wade is a physicist at Imperial College London who’s made it her mission to write and update the Wikipedia pages of as many women in STEM as she possibly can. She inspired us at Lost Women of Science to start our own Wikipedia project to ensure that all the female scientists we profile have accurate and complete Wikipedia pages. In this episode, Jess talks with us about what she does and why she does it.

Dr. Nancy Hopkins, a molecular biologist who made major discoveries in cancer genetics, became an unlikely activist in her early fifties. She had always believed that if you did great science, you would get the recognition you deserved. But after years of humiliations — being snubbed for promotions and realizing the women's labs were smaller than those of their male counterparts — she finally woke up to the fact that her beloved MIT did not value women scientists. So measuring tape in hand, she collected the data to prove her point. In The Exceptions: Nancy Hopkins, MIT, and the Fight for Women in Science, Kate Zernike tells Nancy's story, which led to MIT’s historic admission of discrimination against its female scientists in 1999. Host Julianna LeMieux talks with Kate and Nancy about the journey.

“The only time I ever saw something that I thought was abnormal…there was a human arm in the refrigerator,” said J. Peter Willard about his aunt, Mary Louisa Willard. Otherwise, he insisted, she was just “very normal.” But Mary Louisa Willard, a chemistry professor at Pennsylvania State University in the late 1920s, left a strong impression on most people, to say the least. Her hometown of State College, Pennsylvania, knew her for stopping traffic in her pink Cadillac to chat with friends and for throwing birthday bashes for her beloved cocker spaniels. Police around the world knew her for her side hustle: using chemistry to help solve crimes.
