Ethel Bidwell PhD (12 July 1919 – 23 October 2003) was a British research scientist who investigated blood coagulation and whose discoveries have been used to successfully perform major surgery on patients with severe haemophilia.

Biography

[edit]

Bidwell was born on 12 July 1919 in Haslingden, Lancashire. She studied to become an enzyme chemist.[1]

During World War II, Bidwell worked at the Wellcome Foundation on the toxins of anaerobic bacteria involved in gas gangrene.[1]

In 1950, Bidwell joined the University of Oxford team headed by Gwyn Macfarlane. Two years later, she began to study ox and pig plasma concentration and selective extraction of the blood-clotting protein factor VIII. For her research, she would collect the animal blood from local slaughterhouses, which she transported in large glass containers.[1]

By 1953, she had devised a technique to extract and concentrate bovine factor VIII that was 8000 times stronger than human blood plasma.[1] This was a major clinical advance because could be stored frozen.[1] The research was published in 1954.[2]

In 1959 Bidwell was working on the preparation of human coagulation factors at the Medical Research Council Blood Coagulation Research Unit at Churchill Hospital, Headington, Oxford, assisted by Ross Dike.[1]

Bidwell's research was used to successfully perform major surgery on patients with severe haemophilia through intravenous therapeutic use,[3] with the first patient (after clinical trials) recorded in 1961.[4][5]

Bidwell retired in 1981.[1] She died in 2003 in Durham, England, aged 84.

Legacy

[edit]

In 1999, British neurochemist and head of the History of Modern Biomedicine Research Group (from 2012 to 2017) Tilli Tansey wrote of inviting Bidwell to pariticipate in a witness seminar convened by the Makers of Modern Biomedicine: Testimonies and Legacy project at the Wellcome Collection and chaired by Christine Lee:[6]

"She was extremely reluctant to attend, telling me over the phone when I invited her that she had nothing to contribute. But I knew, from reading the journals of the time and from a casual conversation with a haematologist friend that she was the person who, in the 1950s, had discovered factor VIII, the first reliable treatment for haemophilia, and I wanted to hear her story."
