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."

Elisha Graves Otis

Died 8 Apr 1861 at age 49 (born 3 Aug 1811).American inventor of the automatic safety brake for elevators, which later made high-rise buildings practical. Before this invention, elevators of his time were extremely dangerous. In 1852, he was employed at a New York bed factory. He realized the need for a “safety elevator”to move people and equipment safely to the upper floors of the building. He strikingly demonstrated his solution at the Crystal Palace Exposition in New York in 1854. In front of a large crowd, Otis ascended in his new elevator. He called for the elevator's cable to be cut with an axe, but the elevator platform did not fall. The brake he invented used toothed guiderails in the elevator shaft and a spring-loaded bar that automatically caught in the toothed rail if the elevator car if the cable failed.
