doctor, who had been teaching ophthalmology and dentistry in Würzburg since 1850, opened a private eye clinic in the former birthing house of Adam Elias von Siebold on Klinikstraße 6. On 4 January 1858, he acquired the building, which was donated by the Welzsche Marienstiftung for Poor People with Eye Diseases according to Welz' will in 1878 and became the first Würzburg university eye clinic. The former delivery house, which had been founded in 1805 as the first maternity clinic in Würzburg and a training center for midwives and obstetricians, in 1857, under Friedrich Wilhelm Scanzoni von Lichtenfels, moved to a new building on Klinikstraße 8. As an assistant to the surgeon Cajetan von Textor, Robert von Welz was also one of the pioneers of ether anesthesia in the German-speaking world. He developed an inhaler and, after testing it on himself and others in the winter of 1846/47, published the first work on it, and thus established modern anesthesiology in Würzburg. On 20 December 1857, the university was granted the permission to set up a history seminar with Franz Xaver Wegele as its head. In the winter semester of 1876/77, the number of students at the University of Würzburg exceeded 1,000 for the first time. In 1888, the university, whose medical faculty was one of the most important after Vienna and Prague between 1850 and 1880, received its own pharmaceutical institute. On 28 October 1896, a new main building, called "Neue Universität", was inaugurated on Sanderring (its construction began in 1892); it is still the seat of the university management today. On 3 June 1896, Marcella O'Grady Boveri was the first woman to be admitted to the Würzburg Medical Faculty. The first woman to habilitate at the University of Würzburg was the psychologist Maria Schorn in 1929. A new eye clinic was opened on Röntgenring 12 in 1901, with the portrait of Welz engraved over the portal. Welzhaus on Klinikstraße 6 was affiliated to the women's clinic on Klinikstraße 8, which existed there until 1934, and connected to it by a corridor on the first floor, which was destroyed in World War II and restored in 1974. Welzhaus which was also destroyed except for its outer façade on 16 March 1945, was rebuilt in 1953/1954. The Mathematical Institute was accommodated there until 1974, when the building was affiliated to the Medical Polyclinic. Between 1901 and 1911, five Würzburg researchers, whose
