Frederick Banting (1891-1941): The Farm Boy Who Gave Insulin to the World

How Did a Struggling Country Surgeon Become the Discoverer of Insulin?

Frederick Banting transformed from a failing rural doctor earning $4 daily to the Nobel Prize-winning discoverer of insulin through a combination of desperate circumstances, midnight inspiration, and unwavering determination to help dying children. His journey from poverty to medical immortality demonstrates how breakthrough discoveries often emerge from unexpected sources when brilliant minds confront human suffering with relentless persistence.

Dr. Kumar’s Take

Banting’s story embodies everything I admire about medical discovery - it wasn’t institutional prestige or abundant resources that led to insulin, but a struggling surgeon’s refusal to accept that children had to die from diabetes. His midnight inspiration came from genuine anguish over a patient he couldn’t save, and his decision to give away the patent for $1 reflected the moral clarity that should guide all medical research. Banting proves that the most important medical advances often come from those who remember that medicine exists to serve suffering humanity, not to generate profits.

Nicolae Paulescu: The Forgotten Pioneer of Insulin Discovery

Did a Romanian Scientist Discover Insulin Before Banting and Best?

Nicolae Paulescu, a Romanian physiologist, successfully extracted pancreatic hormone that lowered blood sugar in diabetic dogs in April 1921 - months before Banting and Best’s first successful experiment in July 1921. His work, published in French medical journals, demonstrated that pancreatic extracts could treat diabetes, but World War I disruptions, language barriers, and later political controversies prevented him from receiving proper recognition for his pioneering contributions to insulin discovery.

Rethinking the Discovery of Insulin: Beyond the Toronto Miracle

Was Insulin Really “Discovered” by Just Two Men in Toronto?

While Frederick Banting and Charles Best are credited with discovering insulin, modern historical analysis reveals that insulin’s development involved decades of international research, multiple competing teams, and incremental advances by dozens of scientists. The traditional “eureka moment” narrative oversimplifies a complex collaborative process that began in the 1880s and involved researchers across Europe, America, and Canada working toward the same goal.

The History of the Nobel Prize for Insulin Discovery: A Controversial Decision

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.

The Internal Secretion of the Pancreas: How Banting and Best Discovered Insulin

How Did Banting and Best First Isolate Insulin from the Pancreas?

Frederick Banting and Charles Best discovered that by tying off the pancreatic ducts in dogs, they could allow the enzyme-producing tissue to degenerate while preserving the insulin-producing islets. This breakthrough technique, first published in their landmark 1922 paper “The Internal Secretion of the Pancreas,” enabled them to extract pure insulin without the destructive digestive enzymes that had defeated previous researchers.

The Multiple Lives of Marjorie: The Dogs Who Co-Discovered Insulin

How Did a Dog Named Marjorie Help Prove Insulin Could Save Lives?

Marjorie, lab dog number 410, was a white terrier mix who became the first animal to survive long-term on insulin extracts, living 70 days after her pancreas was removed - far longer than any diabetic animal in medical history. Her survival on Banting and Best’s crude insulin preparations provided the crucial proof that their discovery could sustain life, directly leading to the first human trials that would save millions of lives.
