John Eliot Howard

John Eliot Howard (11 December 1807 – 22 November 1883) was an English chemist of the nineteenth century, who conducted pioneering work with the development of quinine.

He worked at the family pharmaceutical manufacturing business of Howards and Sons.

Howard was originally a Quaker, but became connected with Brethren meetings at the new Brook Street Meeting House in Tottenham, now Brook Street Chapel, which was founded in 1838–1839 by a number of other Christians including Howard's brother Robert; his father Luke (the 'namer of clouds') helped to finance the building of the chapel: a portrait of the father and son hangs in the National Portrait Gallery.

The family lived at Lord's Meade, Lordship Lane, Tottenham.

Howard died in Edmonton, London at the age of 76 and is buried in Tottenham Cemetery.
