Harry Hudson Rodmell
After serving with the Royal Observer Corps during World War II, his graphic design work was largely replaced by commissioned oil paintings of new vessels. These were often produced from plans so that a painting could be completed before the vessel was launched.
Edward Ashmore (British Army officer)
In his later military career, Ashmore was the leading figure in the air defence of the United Kingdom, founding what would eventually become the Royal Observer Corps. He was appointed to devise improved systems of detection, communication and control. A system to be called the Metropolitan Observation Service was created which covered the London area and was known as the London Air Defence Area. This was soon extended towards the coasts of Kent and Essex. The system met with some success and although it was not fully working until late summer 1918 (the last air raid took place on 19 May). The lessons learnt were to provide valuable grounding for later developments.
