Edward Mann Langley (22 January 1851 – 9 June 1933) was a British mathematician, author of mathematical textbooks and founder of the Mathematical Gazette.

[1][2] He created the mathematical problem known as Langley’s Adventitious Angles.

He was educated at Bedford Modern School,[5] the University of London and Trinity College, Cambridge where he was eleventh Wrangler (1878).

[6] 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.

[7] 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'.
