He was the third son of John Martineau, the elder, of Stamford Hill.
He was the third son of John Martineau, the elder, of Stamford Hill.
At that point the Taylors were running a chemical business, backed by Martineau money. John Martineau"s uncles worked in dyeing, textiles and sugar. Under the influence of the Martineaus, the Taylors introduced a high-pressure boiler manufactured by John Braithwaite the younger.
After the business of Taylor & Martineau fell away, he in 1827 went into steel manufacture, with Johann Conrad Fischer and Richard Carter Smith.
He had an earlier patent on a steel process. With his family, John Martineau planned an emigration to the United States of America. After his death in 1832 on board ship, they had to return to London.
Martineau was closely associated with George Birkbeck and the He attended the meeting in early November 1823 at the Crown and Anchor, Strand, attended by about 50 people, representing with Bryan Donkin and Alexander Galloway employers with an interest in technical training of their staff After the mass meeting at the Crown and Anchor on 11 November, there followed a tense and confrontational meeting of 22 November at which the question of subscriptions to the Institution was debated.
Joseph Clinton Robertson and Thomas Hodgskin argued the case for rejecting outside subscription, on the grounds that the autonomy of the mechanics to run their own affairs would be limited by accepting the money.
They were supported by the architect Robert McWilliam. Martineau and Taylor sided with Birkbeck and Francis Place, in backing the subscription scheme brought forward by William Bayley, which was carried. Martineau led the poll for vice-president in the election of 15 December 1823, with the other three vice-presidents being McWilliam, John Millington and John Borthwick Gilchrist.
He was present at the laying of the foundation stone of the Institution in 1824.
With Galloway, Timothy Bramah and Henry Maudslay, Martineau also testified to Joseph Hume"s parliamentary committee on artisans and technology, in the period 1824-1825 when a commercial depression was looming. Connections were particularly significant in the life of John Martineau, a phenomenon that has been remarked on for Dissenter families, such as his.
John and Jane Martineau had a numerous family, including Jane Martineau (1812–1882), known as an academic administrator.
Martineau became a member of the Institution of Civil Engineers in 1821. He was a member of the Provisional Committee of 15, with Richard Taylor, brother of Philip.
