Invention of the Kaleidoscope

kaleidoscope

The kaleidoscope was invented in 1816 by Sir David Brewster who was a Scottish mathematician and physicist noted for his various contributions to the field of optics. Brewster patented his invention in 1817 but thousands of unauthorized reproductions were constructed and sold, resulting in Brewster receiving little financial benefit from his invention. Brewster named the kaleidoscope as he did because of the Greek term “kalos” which means “beautiful”, “eidos” which means “form”, and “scopos” which means “watcher”
