Strasbourg, notably, the philologist Johannes Schefferus (professor Skytteanus), whose little library and museum building at St Eriks torg now belongs to the Royal Society of Sciences in Uppsala. The Queen, who would eventually declare her abdication in the great hall of Uppsala Castle, visited the university on many occasions; in 1652 she was present at an anatomical demonstration arranged at the castle for the young physician Olaus Rudbeck. Rudbeck, one of several sons of Johannes Rudbeckius, a former Uppsala professor who became Bishop of Västerås, was sent for a year to the progressive Leiden University in the Netherlands. Returning in 1654, he received an assistantship in Medicine 1655 and had already gone to work on a program for improving aspects of the university. He planted the first botanical garden, the one which would eventually be tended by Carl Linnaeus and is kept today as a museum of 18th-century botany under the name Linnéträdgården ("the Linnaean Garden"). With the patronage of the university chancellor Magnus Gabriel De la Gardie, Rudbeck was made full professor in 1660, was elected rector for two terms, despite his youth, and started a revision of the work of the other professors and a building spree with himself as an architect. His most significant remaining architectural work is the anatomical theatre, which was added to Gustavianum in the 1660s and crowned with the characteristic cupola for which the building is today known. A gifted scientist, architect and engineer, Rudbeck was the dominant personality of the university in the late 17th century who laid some of the groundwork for Linnaeus and others, but he is perhaps more known today for the pseudohistorical speculations of his Atlantica, which consumed much of his later life. When large parts of Uppsala burned down in 1702, Gustavianum, which contained the university library and its many valuable manuscripts, escaped the fire; local lore has it that the ageing Rudbeck stood on the roof directing the work of fighting the fire. 18th century: Enlightenment and mercantilism The early part of the 18th century was still characterized by the combination of Lutheran orthodoxy and classical philology of the previous century, but eventually, a larger emphasis on sciences and practically useful knowledge developed. The innovative mathematician and physicist Samuel Klingenstierna (1698–1765) was made a professor in 1728, the physicist and astronomer Anders Celsius in 1729, and Carl Linnaeus was made professor of medicine with botany in
