Life

Born the son of Gonville Bromhead, 1st Baronet Bromhead (grandfather of the British second in command of the same name at Rorke's Drift) and Lady Jane ffrench, Baroness ffrench, in Dublin.{{Cite web |url=http://www.royalsoced.org.uk/cms/files/fellows/biographical_index/fells_indexp2.pdf |title=former Fellows of the Royal Society of Edinburgh 1783-2002 |access-date=2015-05-17 |archive-date=2014-01-16 |archive-url=https://web.archive.org/web/20140116140212/http://www.royalsoced.org.uk/cms/files/fellows/biographical_index/fells_indexp2.pdf |url-status=dead }} Bromhead was educated at the University of Glasgow and later at Caius College, Cambridge ( B.A. 1812, M.A. 1815) before taking up the study of law at the Inner Temple in London.{{acad|id=BRMT808ET|name=Bromhead, Edward Thomas ffrench}} He was elected a Fellow of the Royal Society in 1817. Returning to Lincolnshire, he became High Steward of Lincoln. He became the 2nd Bromhead baronet, of Thurlby Hall in 1822.

While at Cambridge, Bromhead was a founder of the Analytical Society, a precursor of the Cambridge Philosophical Society,[https://cambridgeforecast.wordpress.com/2011/03/06/from-the-analytical-society-to-the-philosophical-breakfast-club/ From the Analytical Society to the Philosophical Breakfast Club: Science and the Making of the Modern World] Cambridge Forecast Group, March 6, 2011 together with John Herschel, George Peacock and Charles Babbage, with whom he maintained a close and lifelong friendship. While he was, by all accounts, a gifted mathematician in his own right (although ill-health prevented him from pursuing his studies further), his greatest contribution to the subject is at second hand: having subscribed to the first publication of self-taught mathematician and physicist George Green, he encouraged Green to continue his research and to write further papers (which Bromhead sent on to be published in the Transactions of the Cambridge Philosophical Society and those of the Royal Society of Edinburgh).

Bromhead repeated his success by encouraging the young George Boole from Lincoln. Bromhead was President of the Lincoln Mechanics Institute in the Lincoln Greyfriars, where George Boole's father was the curator. Boole first came to public notice when he gave a lecture on the work of Sir Isaac Newton on 5 February 1835.[https://societyforthehistoryofastronomy.com/ Society for the History of Astronomy] The young Boole's development was fed by books that Bromhead supplied.A.

Bromhead lost his sight when he was old and he died unmarried at his home of Thurlby Hall in Thurlby, North Kesteven on 14 March 1855.
