Georg Forster
By 1783, Forster saw that talking with all of with these people led him away from science. It was also pushing him into deeper debt. He was known to not be very good with money. Because of this, Forster was happy to get a job from the Polish–Lithuanian Commonwealth Commission of National Education. He became the Chair of Natural History at Vilnius University in 1784. At first, he did well in Vilnius. After some time, however, he began to feel isolated. Most of the people that he knew were still scientists from Germany that he met before. In 1785, Forster went to Halle where put in a thesis on the plants of the South Pacific for a doctorate in medicine. Forster's plans to build a natural history scientific centre could not get enough financial support from authorities in Polish–Lithuanian Commonwealth. His famous speech about natural history in 1785 went wouldn't be noticed or even printed until 1843. Eventually, he broke the contract six years before it was over. This is because Catherine II of Russia had asked Forster to go around the world with him on his journey(the Mulovsky expedition). If he came with him, he would be paid as a professor in Saint Petersburg. This made a conflict between Forster and the Polish scientist Jędrzej Śniadecki. Catherine II of Russia, however, decided to not let him go on his journey. After that, Forster left Vilnius. He then went in Mainz. Here he became the head librarian at the University of Mainz. He succeeded Johannes von Müller who was a friend of Forster. He made sure that Forster would succeed him when Müller moved to become the administration of Elector Friedrich Karl Josef von Erthal.
