History of scienceEdit

  • Benjamin Hutchinson publishes Biographia Medica in London, the first English language historical dictionary of international medical biography.




  • An all-platinum kilogramme prototype is fabricated with the objective of equalling as closely as feasible the mass of one cubic decimetre of water at 4 °C. The prototype is presented to the Archives of the French Republic in June and on December 10 is formally ratified as the Kilogramme des Archives and the kilogramme defined as being equal to its mass. This standard holds for the next ninety years.


  • Twelve-year-old Conrad John Reed finds what he described as a "heavy yellow rock" along Little Meadow Creek in Cabarrus County, North Carolina, and makes it a doorstop in his home. Conrad's father, John Reed, learns that the rock is actually gold in 1802, initiating the first gold rush in the United States.
