IT is with regret that we record the death of Mr. Oliver Thornycroft, which occurred on August 24th, at his home in London, after a long illness.
Oliver Thornycroft, who was the son of Sir Hamo Thornycroft, R.A., and a cousin of Sir John E. Thornycroft, K.B.E., the governing director and chairman of John I. Thornycroft and Co., Ltd., was born on April 19, 1885.
After completing his education at Bedales School he went to Clare College, Cambridge, where he took his degree and then began his career as an electrical and mechanical engineer.
In the first world war he served as a lieutenant, R.N.V.R., attached to the Royal Naval Air Service, and afterwards joined the firm of Ricardo and Co., Ltd., where he was appointed chief engineer and works manager.
