Why is a Venetian Blind

Have you ever wondered how the Venetian blind in your office window started its career? And have you ever questioned why in the last few years it has shot into popularity, replacing sash curtains in factory and office windows and even invading homes?
Two hundred years ago, a Frenchman, shipwrecked in the West Indies, tried to keep out the hot sun and still get ventilation in his small, stuffy cabin.
He made a blind with mahogany slats which could be tilted to keep out the strong light, yet catch even a slight breeze and deflect it into his room.
Nobody knows whether this was the first Venetian blind ever made. Nobody knows where the name Venetian blind originated. Venice, however, had nothing to do with it.
Some people think that the blinds trace their par to the crude reed curtains found in the Egyptian; others, that they stem from the wooden blinds medieval India.
These blinds also have been called the forerunners modern air-conditioning, since Indians used to pour cold water over them to cool their homes through evaporation in the moving air.
The Venetian blind of today originated about the time of the Renaissance. Then it was simply a series of slats fitted at an angle into a frame. It could not be raised or lowered.
Not until the middle of the 18th century did men discover how to fashion blinds that could be raised or lowered with cord. After that, during the Victorian age, Venetian blinds rapidly became popular.
Just before the first Jubilee in 1887, an alert young Englishman decided to profit by the popularity of the new-fangled blinds. He studied them, decided they needed s stronger tape to link the slats, and invented a loom which would weave a web in the form of a step ladder –two wide outer pieces and the small rungs at the same time.
If you look at the tape on the Venetian blind in your office, you will see it is the same ladder tape, so-called because the pattern resembles a ladder. –Rockefeller Centre Weekly.
