About the author
Born in Jedburgh, Scotland, on December 11, 1781, David Brewster became one of the best-known scientific figures of the 19th century. He is chiefly remembered for his work in optics, especially his studies of polarized light and the principle now known as Brewster's angle. He also invented the kaleidoscope and later improved the stereoscope, combining careful experiment with a real flair for devices that captured the public imagination.
Brewster was more than a laboratory scientist. He wrote widely, helped edit major reference works, and played an important part in sharing scientific ideas with general readers. His interests reached into photography, astronomy, and scientific instruments, and his career connected research with practical invention in a way that felt lively and modern.
He also held important academic posts, serving as principal of the University of St Andrews and later of the University of Edinburgh. Knighted for his achievements, Brewster died on February 10, 1868, leaving behind a legacy that links serious science with curiosity, wonder, and clear explanation.
