Hugh Quentin Alleyne Reeves (1909-25 October 1955) was a British inventor and engineer. He was one of the most productive and creative engineers attached to Station IX the SOE research station during World War II.
Reeves was born at Seaford Sussex. His first Prep School was West Downs School at Winchester but he transferred to St Cyprian's School, Eastbourne. He then went to Harrow and Sidney Sussex College, Cambridge.
During World War II Major Reeves was attached to Station IX, where he invented both the Welrod and the Sleevegun (similar to the Welrod, though single shot and intended to be concealed up a sleeve), as well as designing the Motorised Submersible Canoe. He was also, among others, behind the silencer for the Sten gun, fluorescent night sights, the Welbum gun and the Welbum. This was made clear in a document that was produced at the end of the war to ensure that the correct people were credited for their inventions.
Reeves was involved in a project to reduce noise in jet engines. While carrying out tests at RAF Bitteswell on a Hawker Hunter Mark V fitted with a Sapphire engine, he was suddenly drawn into the intake of the silencer and was killed.
