Live and act

Rößler was born the son of Philipp Ludwig Roessler (1734-1803), princely Nassau Privy Councilor and lord of the monk's court at Bruchköbel , and Margarethe Antoinette Adam (1754-1796). After completing a commercial apprenticeship in Frankfurt am Main , he acquired a hat factory in Hanau in 1818, which he developed into one of the most important companies in Germany. As a wealthy hat manufacturer, he also dealt with the mineralogy , geognosy and paleontology of the Wetterau and created a collection of minerals and fossils .

He was in close contact with Leopold von Buch and in 1851 published a mineralogical overview of the Wetterau with Gottfried Ludwig Theobald . In 1808 he was one of the founding members of the Wetterau Society in Hanau, of which he was director from 1853 to 1863. From 1848 he was temporarily a member of the Hessian state parliament; In 1858 he was elected to the German Academy of Sciences Leopoldina and in 1859 was one of the founding members of the Free German Hochstift in Frankfurt am Main. In the same year he was elected a corresponding member of the Göttingen Academy of Sciences .

In 1861, the mineral Rösslerite (Mg [AsO ₃ OH] · 7H ₂ O) was described by Johann Reinhard Blum in honor of Rößler . Furthermore, the two fossils Turbonilla rössleri and Cythere rössleri are named after him.
