Why Was the 1923 Nobel Prize for Insulin Discovery So Controversial?
The 1923 Nobel Prize in Physiology or Medicine was awarded to Frederick Banting and J.J.R. MacLeod for the discovery of insulin, but the decision sparked immediate controversy because Charles Best and James Collip were excluded despite their crucial contributions. Banting was so outraged that MacLeod received recognition while Best was ignored that he publicly shared his prize money with his young research partner, creating one of the most contentious awards in Nobel history.
Dr. Kumar’s Take
The Nobel Committee’s decision reveals the complex politics of scientific recognition and the challenge of crediting collaborative discoveries. While Banting deserved recognition for his original insight and determination, leaving out Best, who worked alongside him through the experiments, was deeply unfair. MacLeod was away during the crucial summer of 1921, yet he shared the prize. The committee could only choose among the people who were nominated, and the nominations named Banting and MacLeod, not Best or Collip. This controversy is a reminder that breakthrough science is rarely the work of individuals but emerges from collaborative efforts that deserve shared recognition.
Key Findings
The 1923 prize went to Banting and MacLeod “for the discovery of insulin.” It left out Best, who carried out the experiments alongside Banting, and Collip, whose purification work made human treatment possible. The rules allowed up to three laureates, so the limit did not force anyone out. The committee could only consider people who had been nominated, and the nominations that year named Banting and MacLeod. Best and Collip were not nominated.
Banting’s response was swift and generous: he announced he would split his prize money with Best, while MacLeod shared his portion with Collip. This gesture highlighted the collaborative nature of the discovery, and the choice of laureates has been debated ever since.
Brief Summary
In 1923, the Nobel Prize went to Frederick Banting, who had the original idea and ran the experiments, and J.J.R. MacLeod, in whose laboratory the work was done. Charles Best and James Collip, who made essential contributions, were not nominated and so were not included. The decision created lasting controversy, with Banting publicly criticizing the committee and sharing his prize money with Best. The award highlighted tensions between individual recognition and collaborative science.
Study Design
This is a historical review by two Karolinska Institutet researchers, published in 2021 for the 100th anniversary of insulin’s discovery. It traces the history of diabetes from the Ebers papyrus around 1550 BCE to the discovery of insulin, then turns to the archives of the Nobel Assembly at the Karolinska Institutet to look at the 1923 prize.
Results You Can Use
The paper retraces the steps that led to insulin. Langerhans described the “islands of clear cells” in the pancreas in 1869. Minkowski and von Mering showed in 1890 that dogs without a pancreas died with symptoms of diabetes. Paulescu tried a pancreatic extract that normalized blood glucose in diabetic dogs, but the First World War interrupted his work, and the authors say it never received the recognition it probably deserved. Then Banting, supported by Best, showed in MacLeod’s laboratory that an islet extract could keep diabetic dogs alive for several months. Collip purified the extract, and in January 1922 it saved the lives of people dying of diabetes for the first time. The paper then asks who actually discovered insulin and whether the right people got the prize, drawing on the Nobel Assembly archives.
Why This Matters For Health And Performance
This controversy illustrates how scientific recognition can distort the collaborative nature of medical breakthroughs. The insulin discovery required multiple complementary skills: Banting’s insight, Best’s technical ability, Collip’s biochemical expertise, and MacLeod’s institutional support. Understanding this collaborative reality is a reminder that medical advances depend on teams rather than individual genius, and that proper recognition should reflect these partnerships.
How to Apply These Findings in Daily Life
- Recognize that medical breakthroughs typically involve collaborative teams
- Appreciate the contributions of junior researchers and technical staff
- Understand that scientific credit doesn’t always reflect actual contributions
- Support recognition systems that acknowledge collaborative work
- Learn about the full teams behind medical discoveries you benefit from
- Advocate for equitable recognition in your own professional collaborations
Limitations To Keep In Mind
Historical analysis of the Nobel decision relies on limited archival materials and may not capture all committee deliberations. The 1923 context differed significantly from modern collaborative science, making direct comparisons challenging. Additionally, the Nobel rules let the committee choose only among nominated candidates, so Best and Collip could not have been considered in 1923.

FAQs
Why didn’t the Nobel Committee include all four team members?
The three-person limit was not the reason, since only two laureates were named. The committee could only consider people who had been nominated, and the 1923 nominations named Banting and MacLeod. Best and Collip were not nominated.
How did Banting respond to MacLeod sharing the prize?
Banting was furious that MacLeod received recognition while Best was excluded. He publicly criticized the decision and immediately announced he would share his prize money with Best, calling the young researcher his true partner in the discovery.
Has the Nobel Committee ever acknowledged the controversy?
The Nobel Committee has never officially revised the 1923 award, but historical analyses have increasingly recognized the collaborative nature of the insulin discovery and the problematic exclusion of Best and Collip from the original recognition.
Conclusion
The 1923 Nobel Prize controversy shows how hard it is for prizes to capture the team work behind medical breakthroughs. Banting and MacLeod received the award. Best and Collip, who were not nominated, did not, and whether the right people got the prize is still debated. The lesson still applies: discoveries that save lives usually depend on many contributors, and all of them deserve credit.
