Question: Electroluminescence as a phenomenon was discovered in 1907 by the British experimenter H. J. Round of Marconi Labs, using a crystal of silicon carbide and a cat's-whisker detector. Soviet inventor Oleg Losev reported creation of the first LED in 1927. His research was distributed in Soviet, German and British scientific journals, but no practical use was made of the discovery for several decades. Kurt Lehovec, Carl Accardo and Edward Jamgochian, explained these first light-emitting diodes in 1951 using an apparatus employing SiC crystals with a current source of battery or pulse generator and with a comparison to a variant, pure, crystal in 1953.
Is there an answer to this question: What was the nationality of the man who discovered Electroluminescence?

Answer: British

Question: The most famous passage in Burke's Reflections was his description of the events of 56 October 1789 and the part of Marie-Antoinette in them. Burke's account differs little from modern historians who have used primary sources. His use of flowery language to describe it, however, provoked both praise and criticism. Philip Francis wrote to Burke saying that what he wrote of Marie-Antoinette was "pure foppery". Edward Gibbon, however, reacted differently: "I adore his chivalry". Burke was informed by an Englishman who had talked with the Duchesse de Biron, that when Marie-Antoinette was reading the passage, she burst into tears and took considerable time to finish reading it. Price had rejoiced that the French king had been "led in triumph" during the October Days, but to Burke this symbolised the opposing revolutionary sentiment of the Jacobins and the natural sentiments of those who shared his own view with horrorthat the ungallant assault on Marie-Antoinettewas a cowardly attack on a defenceless woman.
Is there an answer to this question: Who was featured in the most well-known part of Burke's Reflections?

Answer: Marie-Antoinette

Question: The German original of the secret protocols was presumably destroyed in the bombing of Germany, but in late 1943, Ribbentrop had ordered that the most secret records of the German Foreign Office from 1933 on, amounting to some 9,800 pages, be microfilmed. When the various departments of the Foreign Office in Berlin were evacuated to Thuringia at the end of the war, Karl von Loesch, a civil servant who had worked for the chief interpreter Paul Otto Schmidt, was entrusted with these microfilm copies. He eventually received orders to destroy the secret documents but decided to bury the metal container with the microfilms as a personal insurance for his future well-being. In May 1945, von Loesch approached the British Lt. Col. Robert C. Thomson with the request to transmit a personal letter to Duncan Sandys, Churchill's son-in-law. In the letter, von Loesch revealed that he had knowledge of the documents' whereabouts but expected preferential treatment in return. Colonel Thomson and his American counterpart Ralph Collins agreed to transfer von Loesch to Marburg in the American zone if he would produce the microfilms. The microfilms contained a copy of the Non-Aggression Treaty as well as the Secret Protocol. Both documents were discovered as part of the microfilmed records in August 1945 by the State Department employee Wendell B. Blancke, head of a special unit called "Exploitation German Archives" (EGA).

The latter, Louis Kahn's first large-scale American work (1953), was renovated and reopened in December 2006. The Yale Center for British Art, the largest collection of British art outside of the UK, grew from a gift of Paul Mellon and is housed in another Kahn-designed building.
