Question: What is the population of the city where Vordtriede once studied and worked as a teacher? Passage 1:After the Nazis came to power, he emigrated to Switzerland in 1933 and to the United States later. He began his studies in Zurich and worked part-time as a house teacher. Meanwhile, he wrote articles and book reviews for the Neue Zurcher Zeitung, using several pseudonyms because of prohibition of work. He earned his PhD and taught French and German Literature at various universities, including Princeton University and University of Wisconsin-Madison. During a journey to Europe, Vordtriede was surprised by the outbreak of the Second World War and interned as an Enemy alien in occupied France. By interventions, he became free months later and was allowed to go back to America. He met his mother in New York City late in 1941, who also emigrated to the USA. He received the American citizenship in 1946 and became a Guggenheim Fellow in 1957. His sister Franze emigrated in 1947 and went to Philadelphia.
Passage 2:Johann Diederich Gries was born into a prosperous Hamburg family, the fourth of his parents' seven recorded sons. Franz Lorenz Gries (1731-1803), his father, was a merchant and city senator. His mother Johanna also came from a mercantile background. He undertook an apprenticeship in business with a Hamburg wholesale merchant for three years between 1793 and 1795 which, he let it be known, was a miserable thing to have to do. After his elder brother Ludwig had intervened with their father on his behalf he was permitted to embark on a period of study in Law, enrolling at the University of Jena in October 1795. At Jena his naturally affability, his abundance of inoffensive humour and his exceptional talent as a piano player all combined to gain him ready access to the homes and social circles of the professors. He also acquired an extensive network of lifelong friend among his student contemporaries, such as Johann Georg Rist, Johann Friedrich Herbart, , also including a couple of years later Georg Arnold Heise, August Ludwig Hulsen and . At the home of the anatomist Justus Christian Loder he got to know Goethe and Schiller, Herder and Fichte. It was nevertheless striking that while his literary awareness and social circle developed rapidly, he approached his studies in jurisprudence with a marked absence of diligence. Early in 1797 he returned to Hamburg for a visit during which he renewed his friendship with Johann Albert Heinrich Reimarus and Friedrich Heinrich Jacobi. That summer he accompanied Caroline Schlegel and her daughter to Dresden where Schlegel was staying. That also gave him the opportunity to meet Schelling by whom he was much impressed. Around this time he also visited Freiberg where he was warmly received by .
Passage 3:After the political changes in 2000, Croatian cinema proved it could work in a completely free environment for the first time. As a result, at the beginning of this decade Croatian cinema flourishes again, and many critics write about "third golden era" (after the 1950s and 1960s). One of the most popular authors in the contemporary Croatian cinema is Vinko Bresan whose comedies Kako je poceo rat na mom otoku (How the War Started on My Island, 1997), and Marsal (Marshal Tito's Spirit, 1999) mix grotesque humor and political provocation. Bresan's war drama Svjedoci (Witnesses, based on a novel by Jurica Pavicic) was the first feature film from countries of former Yugoslavia which discussed the war crimes committed by "our guys", not the enemy. Film was screened in competition at the Berlin Film Festival in 2003. A Wonderful Night in Split (Ta divna splitska noc, 2004) by Arsen A. Ostojic received a nomination for the European Discovery EFA award, and Tu (Here, 2003) by Zrinko Ogresta was awarded at the Karlovy Vary Film Festival. Among other distinguished contemporary directors, internationally most recognized is Ognjen Svilicic, whose two films premiered at the Berlin Film Festival - Oprosti za kung fu (Sorry about Kung Fu, 2004) and Armin (2006). Armin was also Croatia's submission for the 2008 Academy Award, and although it didn't earn a nomination in the Best Foreign Language Film category, it did nevertheless receive the prestigious Best Foreign Film of 2007 Award given by the International Federation of Film Critics.
