Keywords
Tamoxifen
Tamoxifen is a selective estrogen receptor modulator (SERM) medication used to treat and prevent breast cancer. It works by blocking the action of estrogen in breast tissue, which can help to slow or stop the growth of cancer cells.
Selective Estrogen Receptor Modulator (SERM)
SERMs are a class of drugs that bind to estrogen receptors in the body, but have different effects depending on the tissue. Tamoxifen is a SERM that acts as an antagonist in breast tissue, blocking estrogen's action, but can act as an agonist in other tissues.
Breast Cancer
Breast cancer is a type of cancer that develops in the breast tissue. It is the most common cancer among women worldwide. Tamoxifen is a key treatment for estrogen receptor-positive breast cancer.
ICI (Imperial Chemical Industries)
ICI was a British multinational chemical company that played a significant role in the development of Tamoxifen. The company initially focused on Tamoxifen's potential as a contraceptive but later recognized its value as a cancer treatment.
Arthur Walpole
Arthur Walpole was a British pharmacologist who led the research team at ICI that developed Tamoxifen. He was a strong advocate for the drug's potential as a cancer treatment and faced significant pressure from ICI to focus on other projects.
Craig Jordan
Craig Jordan was a pharmacologist who joined the Tamoxifen research team at ICI in the 1970s. He played a significant role in expanding the drug's use and became widely recognized as the "father of Tamoxifen," overshadowing the contributions of earlier researchers like Dora Richardson.

Lost Women of Science is a podcast that tells the stories of women scientists who have been overlooked or forgotten by history. The podcast aims to highlight the contributions of these women and to inspire future generations of scientists.
Q&A
What was Dora Richardson's role in the development of Tamoxifen?
Dora Richardson was a British chemist who synthesized Tamoxifen in 1962. She played a crucial role in the early research and development of the drug, including conducting early clinical trials that demonstrated its effectiveness in treating breast cancer.
Why was Tamoxifen's development initially slow and met with resistance from ICI?
ICI, the company that developed Tamoxifen, initially focused on its potential as a contraceptive. They were reluctant to pursue its use as a cancer treatment because they believed the market for cancer drugs was not lucrative. This led to delays and setbacks in the drug's development.
How did Craig Jordan's involvement in the Tamoxifen project contribute to Dora Richardson's obscurity?
Craig Jordan, a pharmacologist who joined the Tamoxifen research team later, became widely recognized as the "father of Tamoxifen." His extensive publications and public advocacy overshadowed the contributions of earlier researchers like Dora Richardson, who played a crucial role in the drug's early development.
Why is it important to recognize the contributions of all individuals involved in scientific breakthroughs?
Recognizing the true origins of scientific discoveries is crucial for historical accuracy and for inspiring future generations of scientists. It ensures that credit is given where it is due and that the stories of those who have made significant contributions are not lost to history.
Show Notes
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.
