1950 Obituary 
"GEORGE JUBBER, Wh.Ex., spent the whole of his engineering career in the service of the Crown, being employed for many years at H.M. Dockyard, Portsmouth, and more recently at the Royal Naval Torpedo Factory, Greenock.
He was born in 1896, and was educated at H.M. Dockyard Upper School, where he won a Whitworth Exhibition, and at the Portsmouth Municipal Technical College. His apprenticeship was served in the dockyard from 1911 to 1917, after which he gained experience as an engine fitter and as second-class draughtsman in the Naval Ordnance Department of the Admiralty.
In 1920 he became a temporary draughtsman in the Torpedo Tube Design Office at H.M. Dockyard, Portsmouth, and five years later was promoted to the grade of second-class draughtsman. He transferred to Greenock in 1936 as acting designer and was subsequently confirmed in this appointment, which he continued to hold until the formation of the Royal Naval Scientific Service in which he served as a senior experimental officer up to the time of his death on 10th May 1949.
Mr. Jubber, who was elected an Associate Member of the Institution in 1930, was formerly a part-time lecturer on engineering subjects at the Portsmouth Municipal Technical College."
