On January 11, 1922, 14-year-old Leonard Thompson became the first person to receive an injection of the hormone insulin for Type-1 diabetes—a disease that for millennia had been considered a death sentence for anyone who developed it. The breakthrough would be one of the most consequential in medical history, saving millions of lives.

Diabetes has been recognized as a distinct medical condition for more than 3,000 years, but its exact cause was a mystery until the 20th century. By the early 1920s, many researchers strongly suspected that diabetes was caused by a malfunction in the digestive system related to the pancreas gland, a small organ that sits near the liver. At that time, the only way to treat the fatal disease was through a diet low in carbohydrates and sugar and high in fat and protein. Instead of dying shortly after diagnosis, this diet allowed diabetics to live—for about a year.

In 1914, a political assassination in Sarajevo set off a chain of events that led to the outbreak of the most costly war ever fought to that date. As more and more young men were sent down into the trenches, influential voices in the United States and Britain began calling for the establishment of a permanent international body to maintain peace in the postwar world. President Woodrow Wilson became a vocal advocate of this concept, and in 1918 he included a sketch of the international body in his 14-point proposal to end the war.

In November 1918, the Central Powers agreed to an armistice to halt the killing in World War I. Two months later, the Allies met with conquered Germany and Austria-Hungary at Versailles to hammer out formal peace terms. President Wilson urged a just and lasting peace, but England and France disagreed, forcing harsh war reparations on their former enemies. The League of Nations was approved, however, and in the summer of 1919 Wilson presented the Treaty of Versailles and the Covenant of the League of Nations to the U.S. Senate for ratification
