Power About Armstrong Siddeley
Armstrong Siddeley was a British engineering group that operated during the first half of the 20th century. It was formed in 1919 and is best known for the production of luxury motor cars and aircraft engines.
History
Siddeley Autocars
Siddeley Autocars, of Coventry, was founded by John Davenport Siddeley (1866-1953) in 1902. Its products were heavily based on Peugeots, using many of their parts but fitted with English-built bodies. This company merged with Wolseley in 1905 and made stately Wolseley-Siddeley motorcars. They were used by Queen Alexandra and the Duke of York, the later King Edward VII.
Siddeley-Deasy
In 1909, J. D. Siddeley resigned from Wolseley and took over the Deasy Motor Co and the company became known as Siddeley-Deasy. In 1912 the cars used the slogan "As silent as the Sphinx" and started to sport a Sphinx as a bonnet ornament, a symbol become synonymous with descendent companies. During World War I the company produced trucks, ambulances, and staff cars. In 1915 airframes and aero-engines started to be produced as well.
Armstrong-Siddeley
In 1919 Siddeley-Deasy was bought out by Armstrong Whitworth Development Company of Newcastle upon Tyne and became the Armstrong Siddeley Motors subsidiary. In 1927, Armstrong Whitworth merged its heavy engineering interests with Vickers to form Vickers-Armstrongs. At this point, J. D. Siddeley bought Armstrong Siddeley and Armstrong Whitworth Aircraft into his control. In 1928, Siddeley partnered with Walter Gordon Wilson, inventor of the pre-selector gearbox, to create Improved Gears Ltd, which later became Self-Changing Gears.
