<P0-S0> Roy Emerson and Neale Fraser were the defending champions, but lost in the quarterfinals to Mike Davies and Bobby Wilson. <P0-S1> Rafael Osuna and Dennis Ralston defeated Davies and Wilson in the final, 7 – 5, 6 – 3, 10– 8 to win the Gentlemen' Doubles tennis title at the 1960 Wimbledon Championship. <SEP> <P1-S0> Stephen Owen Davies( before 1889 – 25 February 1972), generally known as S. O. Davies, was a Welsh miner, trade union official and Labour Party politician, who served as the Member of Parliament( MP) for Merthyr Tydfil from 1950 to 1972, and previously Merthyr from 1934 to 1950. <P1-S1> In 1970, when well past 80, he was deselected as parliamentary candidate by his local party association on account of his age. <P1-S2> He fought the constituency in the 1970 general election as an Independent and won comfortably, a rare example in British politics of an independent candidate defeating a major party's organisation. <P1-S3> Most official records show Davies's birth date as November 1886, but he is widely thought to have been born at least four years earlier. <P1-S4> After leaving school aged 12 and working for some years in local pits, Davies studied mining engineering and later took an Arts degree at University College, Cardiff. <P1-S5> He returned to the coalfields in 1913, and established a reputation for militancy. <P1-S6> In 1918 he was elected miners' agent for the Dowlais district of the South Wales Miners' Federation( SWMF), and in 1924 was appointed SWMF's chief organiser, legal adviser, and vice- president. <P1-S7> After a visit to Moscow in 1922 he became a firm advocate of the Soviet Union, a position he maintained for the rest of his life. <P1-S8> After his election to parliament in 1934, Davies was a consistent advocate for the interests of Merthyr Tydfil and the Welsh mining community. <P1-S9> Largely indifferent to party discipline, he defied official Labour policy by championing such causes as disarmament and Welsh nationalism. <P1-S10> His persistence in doing so brought him several suspensions from the party, and he was never offered ministerial office. <P1-S11> An immensely popular figure locally, he was regularly returned at general elections with large majorities. <P1-S12> In 1966, after an unstable colliery spoil tip collapsed on the village of Aberfan with the loss of 144 lives, Davies controversially stated that he had long thought that the tip was unsafe. <P1-S13> He had not reported his suspicions, for fear that an inquiry would cause the closures of local pits. <P1-S14> Not long after his unexpected 1970 electoral triumph, Davies died early in 1972 aged at least 85 and possibly 90 or more. <SEP> <P2-S0> Alfonso Araújo Cotes is a Colombian politician, two time Governor of the Department of Cesar; the first term between September 21, 1968, and August 21, 1970, and the second term between June 7, 1975, and August 30, 1997. <SEP> <P3-S0> August Euler (20 November 1868 – 1 July 1957) was a pioneer German aviator, aircraft constructor and the holder of the first Germany Pilots license, issued in 1909. <P3-S1> After the First World War, he became German Secretary of State for Air, until he retired in 1922. <P3-S2> Euler was born at Oelde in Westphalia and was educated at Oelde and at public schools in Cologne and Aachen and from 1885 started a career in engineering. <P3-S3> He worked for Seidel & Neumann, originally a sewing machine company, which later made cycles and motor cars. <P3-S4> Euler took up cycle racing and then motor racing and became interested in aviation. <P3-S5> In 1908 he started a company to build Voisin aircraft under licence. <P3-S6> In February 1908 August Euler erected a building on the site of the Griesheim Airport, which he relocated from Mainz castle, costing him 2,400 Marks. <P3-S7> In that building he began aircraft production. <P3-S8> On 31 December 1909 he obtained German Pilot's brevet No. 1 and started a flying school. <P3-S9> Before the First World War he moved his factory to Frankfurt and helped set up a German aircraft manufacturers' association. <P3-S10> After the war he was appointed Secretary of State for Air with an instructions to create a ministry for transportation, but with the restrictions of the Versailles Treaty they had little to do, and when the treaty was ratified in 1920 Euler resigned. <P3-S11> Euler built a house in the Black Forest on the Feldberg mountain where he lived in retirement until his death in 1957. <P3-S12> Although his services were requested by the Nazi government during the Second World War he resisted due to his age and remained retired.
