M. "Problem 644." Mathematical Gazette, 11: 173, 1922''〕〔''The Universal Book of Mathematics: From Abracadabra to Zeno's Paradoxes'' by David Darling.

He was educated at Bedford Modern School,〔''Bedford Modern School of the Black and Red'', Andrew Underwood (1981)〕 the University of London and Trinity College, Cambridge〔''Cambridge University Alumni, 1261-1900''〕 where he was eleventh Wrangler (1878). After Cambridge, Langley taught mathematics at Bedford Modern School (1878-1918) where he wrote numerous mathematical text books and his pupils included the famous future mathematician Eric Temple Bell.〔''The Mathematical Gazette'', October 1933〕 Langley became Secretary of the Mathematical Association (1885-1893), founded the Mathematical Gazette (1894) and became its editor (1894–95).〔 In addition to mathematics, EM Langley was a notable botanist and a cultivated blackberry was named Edward Langley in his honour.〔 Langley died in Bedford on 9 June 1933.〔 His former Bedford Modern School pupil, the mathematician Eric Temple Bell, contributed to his obituary in the Mathematical Gazette stating 'Every detail of his vigorous, magnetic personality is as vivid today as it was on the afternoon I first saw him'.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Edward Mann Langley」の詳細全文を読む スポンサード リンク
