In 1923, Frederik Grant Banting received the Nobel Prize in Medicine for his findings in the field of insulin research. Banting's real achievement was isolating insulin. In the same year he founded the "Banting Best Institute", which was continued after his death by Charles Herbert Best.
Banting was born on 14 November 1891 as a farmer's son in the Canadian province of Alliston. After completing his school career, he began studying theology at the University of Toronto. Later, however, he moved to the major subject of medicine and graduated in 1916. He then served in the First World War as a medical officer, until he returned to Canada in 1919 to practice as a doctor, where in the activity as a pediatrician was particularly close to the heart. At the same time he worked the demonstrator for surgery and anatomy. In 1923 he took over the chair of medical research. On February 21, 1941, he died as a result of a lung injury, which he had contracted one day earlier in an emergency landing with a Canadian bomber, during World War II.
Banting was already in the early stages of his medical career for diabetes mellitus. He took research from other colleagues and pursued the idea that diabetes is caused by a lack of a protein that is produced in the pancreas.
Banting's research results from the experiments with dogs. He took the animals from the pancreas and processed it into an extract, which was injected around the dogs again. As hoped, the blood sugar level of the experimental animals dropped.
His first patient
In 1922 Banting treated the first diabetic. Outstanding is the treatment of the then five-year-old Theodore Ryder. He was 75 years old and suffered from diabetes for 70 years - the longest medically diagnosed diabetes. That same year, insulin was presented as a remedy in Washington.
What is insulin?
Insulin is a vital hormonal protein (peptide hormone) that is produced in the pancreas in the area of the islets of Langerhans. The main task of this protein is to lower the blood sugar level and thus it plays a key role in the transport of glucose from the blood plasma and from the tissue fluid into the cell interior.
