John Siddeley, 1st Baron Kenilworth

The eldest son of William Siddeley and his wife born Elizabeth Davenport, J D Siddeley was born in Longsight, Manchester in 1866 and first worked for his father as an apprentice hosier but took night classes in draughting. In 1892, the young bicycle racer and designer was hired as a draughtsman by the Humber Cycle Company. The then managing director of Dunlop picked him out at Humber and hired Siddeley as Dunlop's Belfast sales manager. In 1900 as managing director of Dunlop's Midlands subsidiary Clipper Tyre Company he gained prominence in the motor industry by driving a 6 hp Daimler car through England's Thousand Miles Trial with marked success.[1][2] This followed cycling from Land's End to John o' Groats to publicise the new pneumatic tyre.[3]

He married Sarah Mabel Goodier, daughter of James Goodier of Macclesfield, in 1893 and they lived in Belfast for a short time but by August 1894, they were living in Meriden, Coventry where eldest son, Cyril, was born. They were to have three sons and two daughters.[1]

1902 Siddeley 8 hp

Siddeley founded his Siddeley Autocar Company in 1902 to manufacture cars to Peugeot designs.[1] He had Peugeot-based demonstration cars at the Crystal Palace in 1903. By 1905, the company had a dozen models for sale and some of them were built for him at Vickers' Crayford, Kent factory.

During 1905 Wolseley—which then dominated the UK car market—purchased the goodwill and patent rights of his Siddeley Autocar Company business[4] and appointed Siddeley London sales manager of Herbert Austin's The Wolseley Tool and Motor Car Company Limited owned by Vickers, Sons and Maxim. A few months later Herbert Austin left Wolseley to found his own Austin Motor Company and Siddeley was appointed manager of Wolseley in his place and, without authority, added Siddeley to the badge on the Wolseley cars.

He resigned from Wolseley in 1909 to go into partnership with H P P Deasy and manage the Deasy Motor Company, also of Coventry.[1][2]

1912 Siddeley-Deasy 18-24hp

By 1912, when Deasy resigned because of his ill-health,[2] Siddeley had added his name to the Deasy product's radiator. In November 1912 Deasy's business became—by popular vote of the shareholders—Siddeley-Deasy. During World War I it grew rapidly producing aircraft engines and airframes with the assistance of distinguished staff from the Royal Aircraft Factory at Farnborough as well as motor vehicles including ambulances[1] using Rover chassis and Daimler and Aster engines and employed around 5,000 workers.[5] He was appointed a Commander of the Order of the British Empire in the 1918 New Year Honours for his efforts during the First World War.[6]

In 1918 John Siddeley and his family moved to Crackley Hall, Kenilworth. The same building later became St Joseph's School and is now Crackley Hall School.

Kenilworth Castle, bought and given to the nation by Siddeley

Siddeley was knighted in 1932 when he served as High Sheriff of Warwickshire. Sir John Siddeley was elected president of the Society of Motor Manufacturers and Traders for 1937–1938[9] – the highest honour the British Motor Industry could bestow.[2] That same year he was raised to the peerage as Baron Kenilworth, of Kenilworth in the County of Warwick.[10][11] He was also elected president of the Society of British Aircraft Constructors for 1932–1933[12]—now Society of British Aerospace Companies— and elected president of the Engineering and Allied Employers' National Federation for 1935–1936.[13]

On his retirement he bought and gave to the nation the historic Kenilworth Castle. To commemorate the coronation of King George VI and Queen Elizabeth in 1937, Lord Kenilworth also made a gift of £100,000 to Fairbridge Farm Schools, a charity to offer opportunities and education abroad to young people from broken homes.[2]

After his retirement he moved to Jersey where he died a few days after his wife in November 1953, aged 87, a voluntary tax exile and a rich man.[1]

He was succeeded in the barony by his son Cyril.[1]
