Q: Question: Which of the universities Gyorgy worked at has the highest student enrollment? Passage 1:In 1920, after the end of World War I, Gyorgy was offered a job at the University of Heidelberg as an assistant to the physician and researcher Ernst Moro. He remained at the University of Heidelberg until 1933, obtaining full professorship in 1927 at the age of 34 years. It was at the University of Heidelberg that Gyorgy first discovered and isolated riboflavin along with his colleague Th. Wagner-Jauregg and the Nobel-winning chemist Richard Kuhn. Gyorgy remained at the University of Heidelberg until 1933, when the political unrest in Germany spurred his move to the Nutrition Laboratory at the University of Cambridge in England. He stayed as a researcher in there until 1935, during which time he discovered vitamin B.
Passage 2:Hynde, originally from Akron, Ohio, moved to London in 1973, working at the weekly music paper NME and at Malcolm McLaren and Vivienne Westwood's clothes store. She was involved with early versions of the Clash and the Damned and played in short-lived bands such as Masters of the Backside (1976) and the Moors Murderers (1978 lineup). The Pretenders formed in 1978 after Dave Hill at Anchor Records heard some demos of Hynde's music. He arranged a rehearsal studio in Denmark Street, where a three-piece band consisting of Hynde, Mal Hart on bass (he had played with Hynde and Steve Strange in the Moors Murderers), and Phil Taylor of Motorhead on drums played a selection of Hynde's original songs. Dave Hill was impressed and arranged a day at Studio 51 to record another demo. Although it was rough, he felt he had seen and heard enough "star potential" to suggest that Hynde form a more permanent band to record for his new label, Real Records. Hynde then formed a band composed of Pete Farndon on bass, James Honeyman-Scott on guitar, and Gerry Mcilduff on drums. This band, then without a name, recorded five tracks at Regents Park Studio in July 1978, including "Stop Your Sobbing". Shortly thereafter, Gerry Mcilduff was replaced on drums by Martin Chambers. Hynde named the band "The Pretenders" after the Platters song "The Great Pretender", which was the favourite song of one of her former boyfriends.
Passage 3:The Paus family (earlier spellings include Pauss and de Paus) () is a Norwegian family that first appeared as members of the elite of 16th-century Oslo. Two brothers from Oslo who both became priests, Hans (15871648) and Peder Povelsson Paus (15901653), have long been known as the family's earliest certain ancestors. In his book Slekten Paus ("The Paus family"), genealogist S.H. Finne-Grnn traced the family two further generations back, to Hans Olufsson (died 1570), a member of the royal clergy in Norway before and after the Reformation, who served as a canon at the royal chapel in Oslo, St Mary's Church, the seat of government of Norway at the time, and who belonged to the high nobility by virtue of his high ecclesiastical and governmental office. The name Paus is known in Oslo since the 14th century, notably as the name of the Lawspeaker of Oslo Nikolas Paus (mentioned 13291347) and as the name of one of medieval Oslo's "city farms" (mentioned 13241482) that was probably named after the lawspeaker or his family; while a relation between the older and the younger family of the name in Oslo is plausible, it has not been established. Regardless, the modern Paus family is likely the only surviving family to hail from the medieval city of Oslo which burned down in 1624 without being rebuilt, making it the family with the longest documented history in the Norwegian capital.
