A new soldier was on sentry duty at the main gate. His orders were clear - no car was to enter unless it had a special sticker on the windshield. A big Army car came up with a general seated in the back. The sentry said, "Halt, who goes there?"
The chauffeur, a corporal, says, "General Wheeler."
"I'm sorry, I can't let you through. You've got to have a sticker on the windshield."
The general said, "Drive on!"
The sentry said, "Hold it! You really can't come through. I have orders to shoot if you try driving in without a sticker."
The general repeated, "I'm telling you, son, drive on!"
The sentry walked up to the rear window and said, "General, I'm new at this. Do I shoot you or the driver?"

Carl Wilhelm Scheele

Died 21 May 1786 at age 43 (born 9 Dec 1742). (also Karl) Swedish chemist who discovered oxygen in 1772. Scheele, a keen experimenter, worked in difficult and often hazardous conditions. In his only book, Chemical Observations and Experiments on Air and Fire (1777), he stated that the atmosphere is composed of two gases, one supporting combustion, which he named "fire air" (oxygen), and the other preventing it, which he named "vitiated air" (nitrogen). Due to delay in his publication, he lost priority to Priestley's discovery of oxygen in 1774. Scheele discovered many substances, such as chlorine (1774), manganese (1774), tungsten (1781), molybdenum (1782), glycerol, hydrocyanic (prussic) acid, citric acid, hydrogen sulphide and hydrogen fluoride. He also discovered a process resembling pasteurization.
