History Permalink

Pronunciation

  • IPA: /kəˈlaɪ.dəˌskəʊp/ (UK); /kəˈlaɪ.dəˌskoʊp/ (US)[1]

Etymology

It was coined in 1817 by its inventor, the Scottish scientist Sir David Brewster (1781–1868),[2][3] from Ancient Greek καλός (kalós, “beautiful”), Ancient Greek εἶδος (eîdos, “shape, form”) and English -scope,[4][5][2][3][6] on the model of telescope.[3] It literally means “observer of beautiful forms”.[3]

Earliest recorded meaning

An optical instrument in which loose bits of coloured glass are reflected by mirrors into changing symmetrical patterns (1817).[7][5][2][3]

Semantic evolution

Kaleidoscopes sold by the thousands in the years after their invention, but Brewster failed to secure a patent.[3] The figurative sense, a constantly changing pattern of colours or a succession of shifting phases, is first recorded in 1819 in Lord Byron.[7][2][3] The verb dates from 1891.[7][3]
