Leonard Thompson

Leonard Thompson was a Canadian boy who, in 1922, became the first person to receive insulin as a treatment for diabetes. Before this breakthrough, diabetes was often fatal. His successful treatment marked a significant medical advancement, demonstrating the potential of insulin to control blood sugar levels. This discovery transformed diabetes from a deadly disease into a manageable condition, saving countless lives. Thompson's case highlighted the importance of insulin therapy and paved the way for ongoing research into diabetes treatment, fundamentally changing how the disease is viewed and treated in medicine.
