Langley was born in Buckden on 22 January 1851. He was educated at Bedford Modern School,^{[5]} the University of London and Trinity College, Cambridge^{[6]} 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.^{[7]} Langley became Secretary of the Mathematical Association (1885-1893), founded the Mathematical Gazette (1894) and became its editor (1894–95).^{[6]}^{[8]}

In addition to mathematics, EM Langley was a notable botanist and a cultivated blackberry was named Edward Langley in his honour.^{[7]}

Langley died in Bedford on 9 June 1933.^{[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'.^{[7]}

Bedford Modern School (often called BMS) is a Headmasters' and Headmistresses' Conference (HMC) independent school in Bedford, England. The school has its origins in The Harpur Trust, born from the endowments left by Sir William Harpur in the sixteenth century. BMS comprises a junior school (ages 6–11) and a senior school (ages 11–18).The school has had four names. In 1873, it became Bedford Modern School in order to reflect the School's modern curriculum, providing an education for the professions. BMS provided education not only for the locality but also for colonial and military personnel abroad, seeking good education for their young families.

Buckden, CambridgeshireBuckden is a village and civil parish 3.7 miles (6.0 km) north of St Neots and 4 miles (6.4 km) south-west of Huntingdon. It lies in Huntingdonshire, a non-metropolitan district of Cambridgeshire as well as a historic county of England. The small hamlets of Stirtloe and Hardwick are also in the parish. Buckden is situated close to three major transport networks. The River Great Ouse forms the eastern boundary of the parish; the Great North Road used to pass through the centre of the village, although today there is a bypass just to the west; the East Coast Mainline runs along the eastern side of the Great Ouse river valley in the neighbouring parish of The Offords.

Eric Temple BellEric Temple Bell (February 7, 1883 – December 21, 1960) was a Scottish-born mathematician and science fiction writer who lived in the United States for most of his life. He published non-fiction using his given name and fiction as John Taine.

Joseph Reynolds GreenJoseph Reynolds Green FRS FLS (1848-1914) was an English botanist, physiologist and chemist whose research into plant enzymes was influential in the development of the discipline of biochemistry. He held the chair in Botany at The Pharmaceutical Society of Great Britain and lectured at the University of Liverpool and Downing College, Cambridge. In 1895 he was elected a Fellow of the Royal Society.

Langley’s Adventitious AnglesLangley’s Adventitious Angles is a mathematical problem posed by Edward Mann Langley in The Mathematical Gazette in 1922.

List of Old Bedford ModerniansThe following is a list of some notable Old Bedford Modernians who are former pupils of Bedford Modern School in Bedford, England.

The Mathematical GazetteThe Mathematical Gazette is an academic journal of mathematics education, published three times yearly, that publishes "articles about the teaching and learning of mathematics with a focus on the 15–20 age range and expositions of attractive areas of mathematics." It was established in 1894 by Edward Mann Langley as the successor to the Reports of the Association for the Improvement of Geometrical Teaching. Its publisher is the Mathematical Association. William John Greenstreet was its editor for more than thirty years (1897-1930). Since 2000, the editor is Gerry Leversha.

William HillhouseWilliam Hillhouse FLS (17 December 1850 – 27 January 1910) was the first Professor of Botany at the University of Birmingham (1882-1909). He was one of the first professors appointed to the Mason Science College in Birmingham in 1882 and, prior to that appointment, was University Lecturer in Botany at the University of Cambridge and Lecturer in Botany at Newnham College, Cambridge and Girton College, Cambridge. During the first year of his tenure at Mason, Hillhouse spent time in Bonn in the laboratory of Professor Strasburger who was then one of the most famous botanists of the time. In 1887 he collaborated with Professor Strasburger on a translation of Strasburger’s Practical Botany.Hillhouse was active in advancing education in the Midlands. He was President of the Birmingham Natural History Society and the King’s Heath, Bearwood and Moseley Institutes. He was Chairman of the Birmingham Botanical and Horticultural Society and assisted in making the Botanical Gardens, Edgbaston.
