Input: Consider Input: Question: Who was in charge at Princeton University the year Barschall graduated from that school? Passage:Barschall was born as Heinrich Hermann Barschall in Berlin, Germany; his father was a patent attorney who had received a Ph.D. in chemistry after studying with Nobel Laureates Emil Fischer and Fritz Haber. After beginning study in several universities in Germany, he emigrated to the United States in 1937 during the early Holocaust period; though raised as a Lutheran, he had some Jewish ancestry. He received his Ph.D. from Princeton University in 1940 under the direction of Rudolf Ladenburg; he also worked closely with John A. Wheeler. After a suggestion by Niels Bohr, he carried out in only a few days with fellow graduate student Morton H. Kanner the first demonstration of fission by fast neutrons and thorium and uranium. His thesis was on the interaction of fast neutrons with helium. In a paper with John A. Wheeler he reported the discovery of spin-orbit coupling in neutron scattering.

Input: Consider Input: Question: Which of the cities Demieville studied in after secondary school are located in Continental Europe? Passage:Following his completion of secondary school, Demieville spent time studying in Munich, London, and Edinburgh, where he was able to attend lectures by George Saintsbury at the University of Edinburgh. He then attended the University of Paris, where he wrote an essay on the musical suite of the 17th and 18th centuries and was awarded a licentiate degree in 1914. Demieville then spent the year 1915 studying at King's College London where he was introduced to Chinese, which quickly became his focus. After returning to France, Demieville studied at the Ecole des Langues Orientales Vivantes (School of Living Oriental Languages), after which he moved to the College de France, where he further studied Chinese under the tutelage of Edouard Chavannes and began learning Sanskrit from Sylvain Levi. He earned his Diplome from the Ecole des Langues Orientales Vivantes in 1919.
