Today we wish a happy birthday to Lambert Adolphe Jacques Quetelet, born February 22nd 1796. Quetelet was many things: mathematician, statistician, sociologist, criminologist, meteorologist, and the man who persuaded King William I to found the Royal Observatory of Belgium at Saint-Josse-ten-Noode (a region of Brussels).
Quetelet was also the man who gave us the concept of the Body Mass Index (BMI), or Quetelet Index, as it was known until the 1970s.
1900 ⇒ Main belt asteroid 453 Tea discovered by Auguste Charlois. The reason behind the choice of name remains a mystery. Tea is a member of the Flora family of S-type asteroids, from where the Chicxulub impactor (the big one that probably caused the extinction of the dinosaurs) is thought to have originated.
1966 ⇒ Launch of Cosmos 110.
