Jean-Baptiste Louis Romé de l’lsle
(26 Aug 1736 - 3 Jul 1790)
French crystallographer who, in 1772, confirmed Nicolas Steno’s observation that the angles between corresponding faces of quartz crystals are always the same, although various samples of quartz crystals may differ in appearance. Furthermore, Romé showed that different crystal substances have their own characteristic angles, which he stated in his Law of Constancy of Interfacial Angles.

Science Quotes by Jean-Baptiste Louis Romé de l’lsle (1 quote)
Crystallographic science does not consist in the scrupulous description of all the accidents of crystalline form, but in specifying, by the description of these forms, the more or less close relationship they have with each other.
— Jean-Baptiste Louis Romé de l’lsle
Cristallographie (1793), 1, 91
Quotes by others about Jean-Baptiste Louis Romé de l’lsle (1)
To the exact descriptions he gave of the crystalline forms, he added the measure of their angles, and, which was essential, showed that these angles were constant for each variety. In one word, his crystallography was the fruit of an immense work, almost entirely new and most precious in its usefulness.<[About Jean-Baptiste Romé de l’Isle.]
