A knight went off to fight in...

A knight went off to fight in the Holy Crusades but before leaving he made his wife wear a chastity belt. After tightly securing it to her, he handed the key to his best friend with the instruction: "If I do not return within seven years, unlock my wife and set her free to lead a normal life."
The knight then rode off on the first leg of his journey to the Holy Land, but he had only traveled barely an hour when he was suddenly aware of the sound of pounding hooves behind him. He turned to see that it was his best friend.
"What is the problem?" asked the knight.
His best friend replied: "You gave me the wrong key."

John Gorrie

Died 16 Jun 1855 at age 51 (born 3 Oct 1803). American physician who pioneered the artificial manufacture of ice, refrigeration, and air conditioning. While he was a Naval officer stationed at Apalachicola,Florida, when he needed ice to treat malaria patients with fever, for, he reasoned, people living in cold climates never got malaria. He built a small steam engine to drive a piston in a cylinder immersed in brine. The piston first compressed the air, and then on the second stroke, when the air expanded, it drew heat from the brine. The chilled brine was used to cool air or make ice. He was granted the first U.S. Patent for mechanical refrigeration on May 1851 (No. 8080). Dr. Gorrie was posthumously honored by Florida, when his statue was placed in Statuary Hall in the U.S. Capitol.[The date of death of 16 Jun is as given in the Dictionary of American Biography. However, an obituary notice in the New Orleans Medical and Surgical Journal (1855-1856) gives 29 Jun 1855.]
