IN: Jean-Marie Le Pen (French pronunciation: [Za ma.Ri l@.pen]; born 20 June 1928) is a French politician who has served as Honorary President of the National Front since January 2011 and a Member of the European Parliament (MEP) from France since 2004, previously between 1984 to 2003. He previously served as President of the National Front from 1972 to 2011.

After receiving his law diploma, he enlisted in the Foreign Legion. He arrived in Indochina after the 1954 battle of Dien Bien Phu, which had been lost by France and which prompted prime minister Pierre Mendes France to put an end to the Indochina war at the Geneva Conference. Le Pen was then sent to Suez in 1956, but arrived only after the cease-fire. In 1953, a year before the beginning of the Algerian War, he contacted President Vincent Auriol, who approved Le Pen's proposed volunteer disaster relief project after a flood in the Netherlands. Within two days, there were 40 volunteers from his university, a group that would later help victims of an earthquake in Italy. In Paris in 1956, he was elected to the National Assembly as a member of Pierre Poujade's UDCA populist party. Le Pen has often presented himself as the youngest member of the Assembly, but a young communist, Andre Chene, 27 years old and half a year younger, was elected in the same year. In 1957, he became the General Secretary of the National Front of Combatants, a veterans' organization, as well as the first French politician to nominate a Muslim candidate, Ahmed Djebbour, an Algerian, elected in 1957 as deputy of Paris. The next year, following his break with Poujade, Le Pen was reelected to the National Assembly as a member of the Centre National des Independants et Paysans (CNIP) party, led by Antoine Pinay. Le Pen claimed that he had lost his left eye when he was savagely beaten during the 1958 election campaign. Testimonies suggest however that he was only wounded in the right eye and did not lose it. He lost the sight in his left eye years later, due to an illness. (Popular belief that he wears a glass eye is unfounded.) During the 1950s, Le Pen took a close interest in the Algerian War (1954-62) and the French defence budget. Elected deputy of the French Parliament under the Poujadist banner, Le Pen voluntarily reengaged himself for two to three months in the French Foreign Legion. He was then sent to Algeria (1957) as an intelligence officer. He has been accused of having engaged in torture. Le Pen has denied these accusations, although he admitted knowing of its use.
QUESTION: what services did he offer
IN: Vladimir Vladimirovich Nabokov (; Russian: Vladimir Vladimirovich Nabokov, pronounced [vla'djimjIr na'bok@f] ( listen), also known by the pen name Vladimir Sirin; 22 April [O.S. 10 April] 1899 - 2 July 1977) was a Russian-American novelist, translator and entomologist.

The Nabokovs settled in Manhattan and Vladimir began volunteer work as an entomologist at the American Museum of Natural History. Nabokov joined the staff of Wellesley College in 1941 as resident lecturer in comparative literature. The position, created specifically for him, provided an income and free time to write creatively and pursue his lepidoptery. Nabokov is remembered as the founder of Wellesley's Russian Department. The Nabokovs resided in Wellesley, Massachusetts, during the 1941-42 academic year. In September 1942 they moved to Cambridge where they lived until June 1948. Following a lecture tour through the United States, Nabokov returned to Wellesley for the 1944-45 academic year as a lecturer in Russian. In 1945, he became a naturalized citizen of the United States. He served through the 1947-48 term as Wellesley's one-man Russian Department, offering courses in Russian language and literature. His classes were popular, due as much to his unique teaching style as to the wartime interest in all things Russian. At the same time he was the de facto curator of lepidoptery at Harvard University's Museum of Comparative Zoology. After being encouraged by Morris Bishop, Nabokov left Wellesley in 1948 to teach Russian and European literature at Cornell University, where he taught until 1959. Among his students at Cornell was future U.S. Supreme Court Justice Ruth Bader Ginsburg, who later identified Nabokov as a major influence on her development as a writer. Nabokov wrote Lolita while travelling on butterfly-collection trips in the western United States that he undertook every summer. Vera acted as "secretary, typist, editor, proofreader, translator and bibliographer; his agent, business manager, legal counsel and chauffeur; his research assistant, teaching assistant and professorial understudy"; when Nabokov attempted to burn unfinished drafts of Lolita, it was Vera who stopped him. He called her the best-humored woman he had ever known. In June 1953 Nabokov and his family went to Ashland, Oregon. There he finished Lolita and began writing the novel Pnin. He roamed the nearby mountains looking for butterflies, and wrote a poem called Lines Written in Oregon. On 1 October 1953, he and his family returned to Ithaca, New York, where he would later teach the young writer Thomas Pynchon.
