Sir David Brewster (1781-1868)

Brewster was a physicist who is best known for his experiments with lenses and light. In 1816 he invented the kaleidoscope, and later began experimenting with the stereoscope, invented by Charles Wheatstone (1802-1875). Brewster was the first person to suggest the refracting stereoscope and the two-lens stereo camera. He was elected a Fellow of the Royal Society in 1815 and knighted in 1832.
