Sir John Edward Thornycroft, KBE (1872–1960) was a British mechanical and civil engineer. He worked for the family business of John I. Thornycroft & Company, a shipbuilder to the Royal Navy and others. He played a key role in the early development of destroyers and helped the business to branch into land-based transport as managing director from 1906. During the First World War Thornycroft developed the first coastal motor torpedo boats and launching systems for depth charges and was knighted for his work. He also played a key role in the Second World War, making technical decisions on warship armament. Shortly before his death his son, John Ward Thornycroft succeeded him as chairman and managing director of the company.
Thornycroft was born in Chiswick on 5 September 1872, one of seven children and the eldest son of Blanche Ada née Coules and Sir John Isaac Thornycroft, the founder of the Thornycroft shipbuilding company.[1][2][3] His sister, the naval architect Blanche Thornycroft played an increasingly recognised role in the family engineering business.[4] His aunt and uncle were the sculptors Mary Thornycroft and Hamo Thornycroft.[5] He was educated at St Paul's School, London before receiving engineering training at the Central Technical College in South Kensington.[1][2] After receiving his college diploma in 1892 Thornycroft joined his father's shipyard at Church Wharf, Chiswick where he received further training from his father and John Donaldson.[2]
Family business
Completing his training in 1895 Thornycroft was appointed a draftsman and assistant to the manager of the engine works at the Chiswick yard, where he helped install machinery to torpedo boats and destroyers. Between 1896 and 1902 he was responsible for carrying out sea trials on these vessels and also carried out experimental work on boilers and other machinery. He helped to develop HMS Albatross an 1898 torpedo boat destroyer, an early milestone in the development of the type.[2]
The family business was converted into a publicly listed company in 1901 and Thornycroft was appointed technical director in 1902, with responsibility for all construction work and new designs, including motor vehicles. Thornycroft became managing director in 1906 and was responsible for establishing new shipyards and engine works at Southampton and a motor vehicle works at Basingstoke.[2]
