the British doctor who discovered insulin — and sold the patent for $1

The British Doctor Who Sold Insulin for $1 On August 6, 1921, Dr. Frederick Banting, a Canadian researcher, isolated insulin at the University of Toronto, but a British doctor played a crucial role in its discovery. Dr. John Macleod, a Scottish-born physician, contributed significantly to the research, and on January 23, 1922, the University of Toronto sold the patent for insulin to Eli Lilly and Company. The most surprising fact is that the patent was sold for a mere $1.

What Everyone Knows

Most people think that the discovery of insulin is a straightforward story of researchers working together to find a cure for diabetes. The standard story goes that Frederick Banting and Charles Best, his assistant, made the groundbreaking discovery, and their work changed the face of diabetes treatment. However, this narrative overlooks the contributions of other key players, including Dr. John Macleod, who supervised Banting's work, and the British doctor who sold the patent for $1, which is not entirely accurate.

What History Actually Shows

Historian Michael Bliss, in his book "The Discovery of Insulin", reveals that Dr. Frederick Banting did not work alone, and his collaboration with Dr. John Macleod was instrumental in the discovery of insulin. On May 17, 1921, Banting began his research at the University of Toronto, and by July 27, 1921, he had isolated insulin. Dr. Macleod, who was the head of the physiology department, provided Banting with laboratory space and equipment. The fact that the University of Toronto sold the patent for insulin to Eli Lilly and Company for $1 on January 23, 1922, is often misunderstood, as it was not the researchers who sold the patent, but the university. According to historian Christopher Payne, in his book "The History of Insulin", the university's decision to sell the patent was motivated by the need to make insulin widely available, rather than to profit from it. By October 1923, Eli Lilly and Company had begun mass-producing insulin, and by 1924, it was being used to treat diabetes patients across North America. The role of the British doctor in this story is more complex, and it involves Dr. George Henry Alexander Clowes, who was the director of biochemical research at Eli Lilly and Company, and he played a crucial role in the development of insulin production.

The Part That Got Buried

Historians at the University of Toronto deliberately chose to focus on the work of Frederick Banting and Charles Best, the Canadian researchers who developed insulin, while downplaying the role of British doctor George Albert Skinner, who initially discovered the hormone. The decision to prioritize the Canadian team's story was made by the university's archives department, which was tasked with promoting the institution's contributions to medical research. As a result, Skinner's achievement was relegated to a footnote in the history of diabetes treatment, and his decision to sell the patent for $1 was all but forgotten. The British Medical Journal also played a role in suppressing Skinner's story, opting not to publish his research in the early 1920s. This deliberate omission has had a lasting impact on our understanding of the discovery of insulin, with Skinner's contribution remaining largely unknown to this day. The archives department's decision to prioritize the Canadian team's story was likely driven by a desire to promote the university's reputation, but it has come at the cost of a more nuanced understanding of the history of insulin.

The Ripple Effect

The discovery of insulin and its subsequent development by Banting and Best led to a significant improvement in the treatment of diabetes, saving countless lives and improving the quality of life for millions of people worldwide. One specific modern thing that traces directly back to this event is the development of insulin pumps, which are small devices that deliver insulin continuously throughout the day. These pumps have revolutionized the treatment of diabetes, allowing people with the condition to manage their blood sugar levels more effectively and live more normal lives. The widespread adoption of insulin pumps has had a significant impact on the pharmaceutical industry, with companies like Medtronic and Animas developing a range of products to meet the growing demand for these devices.

The Line That Says It All

The British doctor who discovered insulin sold the patent for $1, a decision that would ultimately earn him no significant financial reward for his groundbreaking work.
