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.
Geoffrey Ambler
In June 1942, Ambler was promoted to acting air commodore and appointed as the third Commandant of the Royal Observer Corps, replacing Air Commodore Drummond Warrington-Morris. During his time in command he oversaw the reorganization of the Corps' headquarters and the subordinate area headquarters.
