In the eighteenth century the King of Poland, Stanisław August Poniatowski wanted to reform the medical education system and organizing public health service. The project of this reform was entrusted to a Swiss scientist Jean-Frédéric von Herrenschwand. He addressed the project to many scientists in Europe by asking their opinion in the matter. Jacob Reinbold Spielmann, a naturalist from Strasbourg sent to Herrenschwand his remarks. He proposed requiring teachers to do field trips and reap the natural history specimen and create a position of professor of mineralogy. It was the oldest proposition of Earth science teaching in Poland.
