Question: Who was Fanny Lewald's partner when Theodor Lewald was born? Passage:Lewald was born in 1860; his aunt was Jewish novelist Fanny Lewald. Lewald became a civil servant in Prussia in 1885, and became the acting Reich Commissioner in 1903. In that role, Lewald attended the 1904 Worlds Fair (held along with the Olympic Games), where he disagreed with Kaiser Wilhelm II over whether the Deutscher Olympischer Sportbund, of which he was the President, should be politically independent. After Berlin won the right to stage the 1916 Summer Olympics (which were later cancelled due to the outbreak of World War I), Lewald encouraged the German Reich to invest in the games, arguing that it was comparable to a World Trade Exhibition. Lewald retired from government in 1923; he had been the under Secretary of State. In 1935, Lewald recommended that Pierre de Coubertin be awarded a Nobel Prize.
