FSSA MICE (11 December 178110 February 1868) was a British scientist, inventor, author, and academic administrator. In science he is principally remembered for his experimental work in
physical optics, mostly concerned with the study of the
polarization of light and including the discovery of
Brewster's angle
Brewster's angle (also known as the polarization angle) is an angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface, with ''no reflection''. When ''unpolarized'' light ...

Although Brewster patented the kaleidoscope in 1817 (GB 4136), a copy of the prototype was shown to London opticians and copied before the patent was granted. As a consequence, the kaleidoscope became produced in large numbers, but yielded no direct financial benefits to Brewster. It proved to be a massive success with two hundred thousand kaleidoscopes sold in London and Paris in just three months.[The Perfectionist Projectionist](_blank)

s. A dogged rival of Wheatstone's, Brewster was unwilling to credit him with the invention, however, and proposed that the true author of the stereoscope was a Mr. Elliot, a "Teacher of Mathematics" from Edinburgh, who, according to Brewster, had conceived of the principles as early as 1823 and had constructed a lensless and mirrorless prototype in 1839, through which one could view drawn landscape transparencies, since photography had yet to be invented. Brewster's personal contribution was the suggestion to use prisms for uniting the dissimilar pictures; and accordingly the lenticular stereoscope may fairly be said to be his invention.
A much more valuable and practical result of Brewster's optical researches was the improvement of the British lighthouse

Brewster pressed its adoption on those in authority at least as early as 1820, two years before Fresnel suggested it, and it was finally introduced into lighthouses mainly through Brewster's persistent efforts.

Of a high-strung and nervous temperament, Brewster was somewhat irritable in matters of controversy; but he was repeatedly subjected to serious provocation. He was a man of highly honourable and fervently religious character. In estimating his place among scientific discoverers, the chief thing to be borne in mind is that his genius was not characteristically mathematical. His method was empirical, and the laws that he established were generally the result of repeated experiment. To the ultimate explanation of the phenomena with which he dealt he contributed nothing, and it is noteworthy although he did not maintain to the end of his life the corpuscular theory he never explicitly adopted the wave theory of light.

, to whom the work has been, frequently, mis-attributed. Given that the book bears Lawrie's name and not Brewster's this is understandable. The book became one of the standard works on early Scottish freemasonry although it has been largely superseded by later works. There is no evidence that Brewster was a Freemason at the time he wrote the book, nor any that he became one later.
Opposition to evolution
Brewster's Christian beliefs stirred him to respond against the idea of the transmutation of species and the theory of evolution. His opinion was that "science and religion must be one since each dealt with Truth, which had only one and the same Author." In 1845 he wrote a highly critical review of the evolutionist work ''Vestiges of the Natural History of Creation
''Vestiges of the Natural History of Creation'' is an 1844 work of speculative natural history and philosophy by Robert Chambers. Published anonymously in England, it brought together various ideas of stellar evolution with the progressive tr ...

''. which he considered to be an insult to Christian revelation and a dangerous example of materialism.
In 1862, he responded to Darwin's ''On the Origin of Species'' and published the article '' The Facts and Fancies of Mr Darwin'' in ''Good Words''. He stated that Darwin's book combined both "interesting facts and idle fancies" which made up a "dangerous and degrading speculation". He accepted adaptive changes, but he strongly opposed Darwin's statement about the ''primordial form'', which he considered an offensive idea to "both the naturalist and the Christian."
Family
Brewster married twice. His first wife, Juliet Macpherson (c. 1776–1850), was a daughter of James Macpherson (1736–1796), a probable translator of Ossian poems. They married on 31 July 1810 in Edinburgh and had four sons and a daughter:
*James (1812–)
*Charles Macpherson (1813–1828), drowned.[
*David Edward Brewster (17 August 1815 –) became a military officer (Lieutenant Colonel) serving in India.][
*Henry Craigie (1816–1905) became a military officer and photographer.][Gordon, p. 244]
* Margaret Maria Gordon (1823–1907) wrote a book on Brewster, which is considered the most comprehensive description of his life.
Brewster married a second time in Nice, on 26 (or 27) March 1857, to Jane Kirk Purnell (b. 1827), the second daughter of Thomas Purnell of Scarborough. Lady Brewster famously fainted at the Oxford evolution debate of 30 June 1860. Brewster died in 1868, and was buried at Melrose Abbey
