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.
Observer Group
The Observer Group began to conduct reconnaissance exercises on both the Atlantic and the Caribbean, (just as the Fleet Marine Force's Fleet Landing Exercises had done a few years before) by the Marines' Platoon Sergeant Russell Corey. He trained the Observer Group in hands-on work at sea abroad fleet submarines and in the tower for instructions in the Momsen lung. Another Marine by the name of Sergeant Thomas L. Curtis was selected from the Observer Group and was sent to the United Kingdom to train with the British Royal Marines and subsequently was transferred to Office of Strategic Services (precursor to the Central Intelligence Agency).
