The Shredder

A young executive is working late one evening. As he comes out of his office about 8 PM he sees the Big Boss standing by the shredder in the hallway, a piece of paper in his hand. "Do you know how to work this thing?" the older man asks. "My secretary’s gone home and I don’t know how to run it."
"Yes, sir," says the young executive, who turns on the machine, takes the paper from the other man, and feeds it in.
"Now," says his boss, "I just need the one copy."

Died 4 Apr 1883 at age 92 (born 12 Feb 1791). American inventor, manufacturer and philanthropist who established The Cooper Union for the Advancement of Science and Art in New York (cornerstone laid in 1854) to provide free technical education of the working class. He invented the first American-built steam locomotive for a common-carrier railway, the Tom Thumb, which made its first run on 28 Aug 1830. His iron-rolling mill produced iron structural beams, included those used to build the Cooper Union, which he wanted to be fire-proof. After founding a telegraph company (1854), he joined Cyrus Field's effort to lay the first tranatlantic cable (1857). Cooper lived to the age of 92, and for his life of philanthropy in New York, the city mourned his passing as one of its most-loved.citizens.«
