5845 Davidbrewster           Discovered 1988 Aug. 19 by R. H. McNaught at Siding Spring.
David Brewster (1781-1868) was a Scottish scientist, a populariser of science and a founder of the British Association for the Advancement of Science. Described as the father of modern experimental optics, Brewster invented or improved polarimeters, stereo cameras, the stereoscope, the kaleidoscope, and several other instruments.
