Overview

The discovery of insulin in 1921 by Frederick Banting and Charles Best at the University of Toronto transformed diabetes from a fatal diagnosis into a manageable condition.

Key Milestones

  • 1869: Paul Langerhans describes pancreatic islet cells
  • 1889: Minkowski and von Mering link pancreas to diabetes
  • 1921: Banting and Best isolate insulin from dog pancreas
  • 1922: First human injection of insulin
  • 1923: Banting and Macleod win Nobel Prize
  • 1955: Frederick Sanger sequences insulin
  • 1963: First synthetic insulin produced
  • 1982: Recombinant human insulin approved (Humulin)

Impact

Insulin was the first peptide hormone to be isolated, sequenced, and produced recombinantly. It set the precedent for all subsequent peptide therapeutic development.
