Daniel Vorländer (11 June 1867 – 8 June 1941) was a German chemist who synthesized most of the liquid crystals known until his retirement in 1935.
Vorländer was born in Eupen in Rhenish Prussia. He studied chemistry at Kiel University, the Ludwig-Maximilians-Universität München, and the Friedrich Wilhelm University of Berlin, after which he became a professor at the University of Halle-Wittenberg.Daniel Vorlander @ Martin Luther University of Halle-Wittenberg
Vorländer applied his knowledge of molecular structure to select those exhibiting the crystalline liquid state. In particular a linear molecular geometry was conductive. "Over the years Vorländer and his students synthesized hundreds of liquid crystalline compounds. An interesting discovery was that amongst the slimy liquid crystals were many soap and soap-like compounds."David Dunmur & Tim Sluckin (2011) Soap, Science, and Flat-screen TVs: a history of liquid crystals, pp 43–9, Oxford University Press
Vorländer served as a volunteer during World War I, during which he received the Iron Cross. He died in Halle.
