James Warren (1802-1870) of Montague Terrace, Mile End Road, London

1802 November 23rd. Born in London the third son of Daniel Warren and his wife Happy Ingate of Welling, Bexley, Kent.

Warren was a merchant engaged with his brother, Captain Daniel Warren (born 29 April 1798; died following an accident at Waterloo station, London, on 27 January 1877) in the East India trade. Though not trained in engineering, he became interested in developing an iron truss for bridges.

On 15 August 1848, in conjunction with Willoughby Theobald Monzani, an application was made and it was enrolled on 15 February 1849 (No. 12,242) and became known as the Warren truss. Its first major application on a railway was to carry the GNR main line over a branch of the Trent at Newark. The second important use of the Warren truss was in the Crumlin Viaduct.
