William George Armstrong
William George Armstrong - British engineer and industrialist, artillery designer, in 1859, became an artillery engineer of the Ministry of War and began production of its weapons in the Woolwich Arsenal. In 1897, three years before his death, the firm merged with its old rival Whitworth, forming a company Armstrong Whitworth.
Armstrong Whitworth established an Aerial Department in 1912. This later became the Sir W. G. Armstrong Whitworth Aircraft Company. When Vickers and Armstrong Whitworth merged in 1927 to form Vickers-Armstrongs, Armstrong Whitworth Aircraft was bought out by J. D. Siddeley and became a separate entity.
