notes: label: Description
content: Augustin Fresnel (1788-1827) was a French physicist who, in 1821, announced that compressed glass causes double refraction of light passing through it, thus behaving in this regard as unstressed piece of Iceland spar. This device demonstrates that phenomenon. The “J. Duboscq-Soleil / rue de l’Odeon 21 / à Paris” inscription is that of Jules Duboscq, an instrument maker who apprenticed with J. B. F. Soleil, and used the “Duboscq-Soleil” signature in the early 1850s.
