The story
The noun is derived from Ancient Greek καλός (kalós, “beautiful, lovely”) + εἶδος (eîdos, “form, image, shape”) + English -scope (suffix denoting an instrument used for examination or viewing), coined by the British scientist David Brewster (1781–1868) in his 1817 patent for the invention: see the quotation.
