In 1847 the student of medicine Theodor Sluyter (1817-1895) from Greifswald published his thesis in Berlin including the first well-documented case of human pulmonary aspergillosis. In 1856 Rudolf Virchow (1821-1902) classified the depicted fungi as an Aspergillus species. Possibly Carl Ferdinand Eichstedt (1816-1892) carried out the autopsy. He is known by the first description of a fungus as the cause of pityriasis versicolor in 1846. Further involved scientists from Greifswald were Wilhelm Baum (1799-1883), Theodor Litzmann (1815-1890) and the botanist Johann Konrad Schauer (1813-1848). Their curricula vitae are given in further details as well the curriculum of T. Sluyter.
