The kaleidoscope was invented in 1816 by Sir David Brewster (1781-1868) of Scotland. Brewster was a child prodigy, built a telescope at age 10, and entered the University of Edinburgh at age 12 where his primary studies were optics and the physics of light. For more information click here.
I enjoy and have a few kaleidoscopes. What do you collect?
