After graduating in 1886, Wölfflin published the result of a years' travel and study in Italy, as his "Renaissance und Barock" (1888), the book that evaluated the pathological "Baroque" as a new stylistic category and a serious area of study. For Wölfflin, the 16th-century art now described as "Mannerist" was part of the Baroque aesthetic, one that Burckhardt before him as well as most French and English-speaking scholars for a generation after him dismissed as degenerate. On the death of Jacob Burckhardt in 1897 Wöllflin succeeded him in the Art History Chair at Basel. He is credited with having introduced the teaching method of using twin parallel projectors in the delivery of art history lectures, so that images could be compared when magic lanterns became less dangerous. Sir Ernst Gombrich recalled being inspired by him, as well as Erwin Panofsky. Wölfflin taught at Berlin University from 1901 to 1912, Munich University from 1912 to 1924 and Zurich University from 1924 until his retirement.
