Question: Gerhard Thiele and Patrick Baudry, have which occupation in common?
Context: "Gerdes" , or "Geerdes", is a surname of German origin.  It is a patronymic name, i.e. it comes from "son of Gerhard".  When around 1800 the Prussian government under French occupation decided to fix the surnames, the contemporary "son of Gerhard" had to keep his name.  In Ostfriesland, the law was ignored until at least 1811. The Convention of Balta Liman of 1 May 1849 was an agreement between the Russian Empire and the Ottomans regulating the political situation of the two Danubian Principalities (the basis of present-day Romania), signed during the aftermath of the Revolutions of 1848.  Moldavia, which had been placed under Russian occupation in late spring 1848 following a revolutionary attempt, and Wallachia, where a liberal Provisional Government had briefly assumed power before facing a common Ottoman-Russian reaction, were confirmed their previous status of Ottoman suzerainty and Russian protectorate (first established in 1831–32 by the "Regulamentul Organic").  Minor provisions were added, signifying a relative increase in Ottoman influence—namely, "hospodars" were no longer elected by the local National Assemblies for life, and instead appointed by the Sublime Porte for seven-year terms.  A common military presence was maintained until 1851.  The document led to the appointment of Barbu Dimitrie Ştirbei as hospodar of Wallachia and Grigore Alexandru Ghica as hospodar of Moldavia.  The Convention was rendered void by the Crimean War (during which the Principalities fell under Austrian occupation), and the statutory system itself was annulled by the 1856 Treaty of Paris. Mesne (pronounced "mean") profits are sums of money paid for the occupation of land to a person with right of immediate occupation, where no permission has been given for that occupation.  The concept is feudal in origin, and common in countries which rely on the English legal system (including many former British colonies).  The word is derived from the root word demesne. Patrick Pierre Roger Baudry (born March 6, 1946 in Cameroon), is a retired Lieutenant Colonel in the French Air Force and a former CNES astronaut.  In 1985, he became the second French citizen in space, after Jean-Loup Chrétien, when he flew aboard NASA's Space Shuttle mission STS-51-G. The Girl and the Boy (French:La fille et le garçon) is a 1931 comedy film directed by Roger Le Bon and Wilhelm Thiele and starring Lilian Harvey, Henri Garat and Lucien Baroux.  It was made by the major studio UFA as the French-language version of "Two Hearts Beat as One", which also starred Harvey.  Such multiple-language versions were common in the early years of sound before dubbing became more widespread. "Magdalena" premiered at the Los Angeles Civic Light Opera on 26 July 1948, pursuant to a commission from Edwin Lester, president of that organization.  Arthur Kay conducted Irra Petina, Dorothy Sarnoff, John Raitt, Hugo Haas, Gerhard Pechner, A. Garcia, Melva Niles, Henry Reese, Ferdinand Hilt, J. Arthur, Betty Huff, Christine Matsios, Leonard Morganthaler, John Schickling, Lorraine Miller, Gene Curtsinger, Patrick Kirk, Betty Brusher, and Jack Cole (soloists).  Jules Dassin directed, Jack Cole was the choreographer, and the chorus was prepared by Robert Zeller.  Broadway veterans Howard Bay (settings and lighting) and Irene Sharaff (costumes) were also part of the creative team.  It was also presented in San Francisco at the Curran Theatre (San Francisco Light Opera) for several performances beginning August 16, 1948.  The same production opened in New York City at the Ziegfeld Theatre on September 20, 1948, and closed on December 4 after 88 performances.  Raitt, Sarnoff, and Haas reprised their roles.  No recording was made due to a strike.  "Magdalena" was revived in concert form under conductor Evans Haile on November 24, 1987, at Alice Tully Hall in New York's Lincoln Center; a recording with a slightly different cast was made in RCA's studios in 1988 and issued by CBS (later Sony) in 1989 (ASIN: B0000026QF).  The work was performed in Australia in the 1990s as part of the Opera Festival in Ballarat, Victoria, again under Haile.  More recently the Théâtre du Châtelet in Paris announced a production to open in May 2010, with Kate Whoriskey directing and Warren Adams supplying choreography. Gerhard Raff (born August 13, 1946 in Stuttgart-Degerloch, then American Zone of Occupation, later West Germany) is a German historian, editor and publisher, well known around Swabia (eastern and southern Baden-Württemberg) for his writings on history in the Swabian dialect of German, e.g. in a weekly column ("Raffs Raritäten", i.e. Raff's rarities) for the Stuttgarter Zeitung. Dr. Gerhard Paul Julius Thiele (born September 2, 1953) is a German physicist and a former ESA astronaut. The Madonna's Secret is a 1946 American film noir crime film directed by Wilhelm Thiele and starring Francis Lederer, Gail Patrick, Ann Rutherford and Edward Ashley. Gerhard Rohner (born Nieder-Heiduk 23 May 1895: died Bonn 7 March 1971) was a politician in the Soviet occupation zone of Germany, which later became the German Democratic Republic.  He became a leading member of the moderately right-wing CDU (party) which was not the party favored by the Soviet administrators and the new Moscow trained political establishment.  After sustained violent attacks from the new country's ruling SED (party) he abandoned his political career and, in February 1952, fled the country.
