Finding Dora Richardson: The Forgotten Developer of Tamoxifen, a Lifesaving Breast Cancer Therapy - Episode Two
10/31/24 • 36 min
Although initial clinical trials of tamoxifen as a treatment of breast cancer were positive, Imperial Chemical Industries (ICI) did not believe this market would be commercially viable. The company had hoped for a contraceptive pill – tamoxifen didn’t work for that – not a cancer treatment. In 1972 the higher-ups at ICI decided to cancel the research. But Dora Richardson, the chemist who had originally synthesized the compound, and her boss, Arthur Walpole, were convinced they were on to something important, something that could save lives. They continued the research in secret. Tamoxifen was eventually launched in the U.K. in 1973 and went on to become a global success, saving hundreds of thousands of lives. Dora Richardson’s role in its development, however, was overshadowed by her a male colleague and all but forgotten.

Finding Dora Richardson - The Forgotten Developer of Tamoxifen
In the early 1960s, chemist Dr. Dora Richardson synthesized a chemical compound that became one of the most important drugs to treat breast cancer: tamoxifen. Although her name is on the original patent, her contributions have been lost to history.
In the first episode of this two-part podcast, Katie Couric introduces us to Dora’s story. Lost Women of Science producer Marcy Thompson tracked down Dora’s firsthand account of the history of the drug’s development. This document, lost for decades, tells the story of how the compound was made and how Imperial Chemical Industries, where Richardson worked, almost terminated the project because the company was hoping to produce a contraceptive, not a cancer therapy.

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.
