Paul Traugott Meissner (23 March 1778, Mediasch, Transylvania – 9 July 1864) was an Austrian chemist.
Beginning in 1815 he served as an adjunct at the newly founded Polytechnic Institute in Vienna, where shortly afterwards, he became a professor of technical chemistry.
He conducted experiments with heating systems for steamships and railway carriages and also created a fuel-efficient cooking range.
[3] Described as a free thinker, Meissner was known for his controversial views that made adversaries out of contemporaries that included Vienna technologist Johann Joseph von Prechtl (1778-1854).
German chemist Justus Liebig (1803-1873) specifically blamed Meissner for what he perceived was the plight of Austrian chemistry.
