Biographical Information: Born in New Orleans, Louisiana, USA, Harold Groos joined the Royal Canadian Navy in 1930. Over the following four years, as a Cadet and then as a Midshipman, Harold trained in a succession of RN ships and establishments (mostly heavy units) of which Hood was one. The length of his stay on board is not known.
His suitability for seagoing command was noticed early: during World War II he commanded a succession of vessels, starting (as a Lieutenant) with the Flower class corvette HMCS Orillia and culminating in 1944 (as a Lieutenant Commander) with the magnificent new Tribal class 'super destroyer' HMCS Huron.
The fine career of Harold Groos continued after the war, and he ended his service as a Rear Admiral. He left the RCN on 30th January 1965 and passed away in July 1987.
