In 1905, in the year that Sadie G Leonard was born, the German born physicist, Albert Einstein, proposed the Special Theory of Relativity: 1) that observers can never detect uniform motion except relative to other objects and that 2) unlike the velocity of massive objects, the speed of light is a constant and is the same for all observers independent of their constant velocity toward or away from the light source. Not such simple concepts that lead to the equation everyone now knows: E = mc2.

In 1917, when she was merely 12 years old, Dutch exotic dancer Mata Hari was convicted and executed as a German spy. Since Mata Hari, born Margaretha Geertruida "Margreet" MacLeod, was a citizen of the Netherlands (which remained neutral in World War 1), she could travel freely in Europe. Her travels (and her romantic entanglements) raised suspicion and she was arrested by the French and found guilty. There is still controversy about her guilt although her name has become synonymous with a seductive female spy.

In 1937, Sadie was 32 years old when on May 6th, the German zeppelin the Hindenburg caught fire and blew up. The Hindenburg was a passenger ship traveling to Frankfurt Germany. It tried to dock in New Jersey, one of the stops, and something went wrong - it blew up. Thirty-six people were killed out of the 97 on board - 13 passengers, 22 crewmen, and one ground worker. The reasons for the explosion are still disputed.

In 1941, she was 36 years old when in his State of the Union address on January 6th, President Roosevelt detailed the "four freedoms" that everyone in the world should have: Freedom of speech, Freedom of worship, Freedom from want, and Freedom from fear. In the same speech, he outlined the benefits of democracy which he said were economic opportunity, employment, social security, and the promise of "adequate health care".

In 1985, when she was 80 years old, on March 15th, the first internet domain name was registered - Symbolics.com. Symbolics, Inc., a spinoff of the MIT AI Lab, was a computer manufacturer headquartered in Massachusetts. The company no longer exists and the domain name was sold 25 years later.
