Sir David Brewster
The Kaleidoscope was invented in 1816 by Sir David Brewster,
a Scottish scientist and member of the Royal Society.

The kaleidoscope is a optical instrument that uses mirrors to produce ever changing symmetrical designs.
It often resembles a small hand-held telescope.
The scope is tube shaped, at one end is an eyepiece, at the other end a glass cylinder usually filled with small pieces of colored glass. In the center of the tube are ether two of three rectangular mirrors.

Viewed though the eyepiece the mirrors cause the colored glass to form many symmetrical patterns.

When the tube is rotated,the small pieces of colored glass move, changing the patterns dramatically.

 
Delighted with his fascinating device,
Sir David gave it a name made up of the Greek words:

kalos (beautiful) + eidos (form) + scopos (watcher)=

KALEIDOSCOPE: THE BEAUTIFUL FORM-WATCHER
