In January 1922, Leonard Thompson was a teenager dying of diabetes at a Toronto hospital. There was no treatment for diabetes, and most adolescents succumbed to the disease within a year of diagnosis.
Thompson endured diabetes for almost three years. What the best doctors can advise was a nearly star diet with reduced Thompson Up to just 65 pounds. His medical team agreed that he was destined. However, Thompson was then given two injections of insulin, an experimental intervention. Within a day, his blood sugar level had stabilized. A life-saving drug has been born.
Soon, insulin was mass produced, saving millions of lives. A scientist who was recognized as Discovery’s Nobel Prize winner. However, this victory brought lifelong hostility among the winners.
When was insulin discovered?
1922, Physician Frederick Bunting I was teaching At the University of Toronto. He wanted to further test “pancreatic substances” as a way to treat diabetes. About 30 years ago, scientists had discovered that insulin was produced in the pancreas, and that diabetics were unable to produce their own insulin.
Bunting approached university scientist John McLeod with his research interest. MacLeod supported Bunting and worked with one of his top students, Charles Best, to use his lab.
Together, bunting and the best I’ve started experimenting with dogs May 1921. The dogs were given pancreas and were given pancreatic extract injections, which proved to lower blood sugar levels. By the second half of 1921, JB Collip had joined the research team and focused on purifying insulin for human injections.
After Thompson received a life-saving injection, MacLeod intervened to guide the drug to the mass market. Working with his contact information, he secured a license and a patent. He connected with drug company Eli Lily, taking medications ranging from dog “thick brown sludge” to regulated medicines found in drug lockers in all hospitals.
“And while all of these tasks may have the glamour and appeal of life-saving research, without them, insulin would not have been any more than a lab bench.” Insulin: bent wood Visiting Fellow at the University of Leeds in the UK.

How did insulin save lives?
The reaction was rapid. Eli Lily started mass-produced insulin, which is derived from cows and pigs. Formula saved millions of lives, but there were restrictions. The patient required multiple daily injections to process it quickly and safely lower blood sugar levels. There were supply issues and a notable allergic reaction to animal by-products.
Novo Nordisk began producing slower insulin in 1936. The next major breakthrough took place in the 1980s when Elirily introduced biosynthetic human insulin. Insulin from cows and pigs was no longer needed because it was derived from genetically designed versions E. coli Bacteria.
Insulin saved the lives of diabetics. the current, 2 million Americans He has number I diabetes, including 304,000 children and adolescents. Over a century ago, children with diabetes faced certain deaths, Approximately 66% He died within 1.4 years of diagnosis. Supporters praise the scientists who discovered a life-saving drug and put it on the market.
On the issue, scientists agreed on who was worthy of credit.
Insulin discovery conflict
The 1923 Nobel Prize in Physiology or Medicine was awarded to both Bunting and MacLeod. Bunting made the discovery, but the committee believed that insulin would not be on the market without MacLeod. Bunting wasn’t happy.
“He was furious. He was totally alive,” Hall said. “My sense of pride and accomplishment in receiving the highest acclaim of science was completely covered by his sense of anger that he had to share the award with MacLeod.”
Bunting felt that he should share the award with the best, and McLeod should have been ruled out. MacLeod felt that Colip made a significant contribution despite being a fugitive on the team. Bunting split the prize money with the best, and MacLeod did the same with Collip.
The two winners parted ways. MacLeod returned to his hometown of Scotland in 1928 and died in 1935 in his late 50s. Bunting died in 1941 after being injured in a plane crash.
The feud among scientists was legendary, but Hall says it’s important not to allow them to obscure how scientific processes lead to discoveries.
“This is something we should do as a science historian,” Hall says. “It’s not to undermine science, it’s the exact opposite. By flaws and oversimplification of popular legendary explanations, it reveals that science practice is much more complicated and much more rich and interesting for it.”
