The Wikipedia article of the day for October 21, 2016 is S. O. Davies.
Stephen Owen Davies (died 25 February 1972) was a Welsh coal miner and Labour Party politician who was Member of Parliament for Merthyr Tydfil from 1934 to 1972. In 1918 he became miners' agent for the Dowlais district of the South Wales Miners' Federation, and in 1924 was appointed its chief organiser, legal adviser, and vice-president. Elected to parliament in 1934, Davies consistently defied official Labour policy to champion causes such as disarmament and Welsh nationalism, with a persistence that brought him several suspensions and ensured that he was never offered ministerial office. After a spoil heap at a coal mine collapsed in the village of Aberfan on 21 October 1966 killing 116 schoolchildren and 28 adults, Davies controversially said that he had long thought that it was unsafe. He had not reported his suspicions for fear that an enquiry would cause the closures of local pits. In 1970 he was deselected as parliamentary candidate by his local party association on account of his age, but won the seat in the general election as an Independent, a rare example in British politics of an independent candidate defeating a major party's organisation.
