When was insulin discovered?

Insulin, a hormone that regulates sugar levels in the body, was first discovered in 1889 by German physiologist Oskar Minkowski (1858–1931) and German physician Joseph von Mering (1849–1908).

The first genetically engineered human insulin was produced by American scientists in 1978.
