Question: Who was the first president of the college where Heinrich studied? Passage:Georg Heinrich August Ewald (16 November 1803 – 4 May 1875) was a German orientalist, Protestant theologian, and Biblical exegete. He studied at the University of Göttingen. In 1827 he became extraordinary professor there, in 1831 ordinary professor of theology, and in 1835 professor of oriental languages. In 1837, as a member of the Göttingen Seven, he lost his position at Göttingen on account of his protest against King Ernst August's abrogation of the liberal constitution, and became professor of theology at the University of Tübingen. In 1848, he returned to his old position at Göttingen. When Hanover was annexed by Prussia in 1866, Ewald became a defender of the rights of the ex-king. Among his chief works are: Complete Course on the Hebrew Language (), The Poetical Books of the Old Testament (), History of the People of Israel (), and Antiquities of the People of Israel (). Ewald represented the city of Hanover as a member of the Guelph faction in the North German and German Diets.

Question: How many citizens live in the suburb that Chappell grew up in? Passage:Chappell grew up in the beachside suburb of Glenelg and attended the local St Leonard's Primary School where he played his first competitive match at the age of seven. He was later selected for the South Australian state schoolboys team. He then enrolled at Prince Alfred College, a private secondary school noted for producing many Test cricketers, including the Australian captains Joe Darling and Clem Hill. His other sporting pursuits included Australian football and baseball: Chappell's performances for South Australia in the Claxton Shield won him All-Australian selection in 1964 and 1966 as a catcher. He credits Vic Richardson, who had represented both SA and Australia in baseball during the 1920s, for his love of the sport. At the age of 18, his form in grade cricket for Glenelg led to his first-class debut for South Australia (SA) against Tasmania in early 1962.
