2. Possibly the first careful observations and analyses (in German) of the liquid–crystallinity of suspensions of mineral particles. The subtitle (‘A new kind of anisotropic fluid material’, i.e. our modern definition of a liquid crystal) indicates very well the level of understanding reached by Zocher, in contrast with previous reports by others. Anyone really interested in this field should at least take a look at this article.
