New Delhi, 10 January – The day of 11 January 1922 stands as a landmark in the history of medical science. On this day, for the first time in Canada, a diabetes patient was successfully given an insulin injection, opening the door to controlling a disease that was then considered almost a death sentence. This breakthrough not only saved one life but also became a beacon of hope for millions worldwide.
At the centre of this historic achievement was 14-year-old Leonard Thompson, who suffered from Type 1 diabetes. At that time, there was no effective treatment available for diabetes. Patients were placed on extremely strict diets, which gradually led to weakness and malnutrition. Doctors had no concrete method to stop or control the disease. Leonard’s condition was rapidly deteriorating, and his chances of survival were nearly gone.
Meanwhile, at the University of Toronto, Dr Frederick Banting, along with colleagues Charles Best, James Collip, and John Macleod, were working on isolating a hormone from the pancreas. This hormone was later named ‘insulin’. After many unsuccessful attempts and technical challenges, the scientists succeeded in preparing insulin in a purified form.
On 11 January 1922, Leonard Thompson received the first dose of insulin. Though the initial results were not perfect, within days the improved insulin produced remarkable effects. The patient’s blood sugar levels began to stabilise, his health improved rapidly, and he was brought back from the brink of death. This moment became a decisive turning point in medical history.
Following this success, insulin production was scaled up and soon became the foundation for diabetes treatment worldwide. A disease once deemed incurable transformed into a manageable condition. Millions of patients gained the opportunity to live normal, active, and longer lives.
The event of 11 January 1922 was not just a scientific breakthrough but a triumph of human curiosity, research, and compassion. Today, this day is remembered as a symbol of hope, innovation, and life-saving progress in medical science.
