Clarence Howard-Johnston
British Rear-Admiral of the 20th century
Rear-Admiral Clarence Dinsmore Howard-Johnston, (13 October 1903 – 26 January 1996) was a British Royal Navy officer and inventor. He specialised in anti-submarine warfare during the inter-war years, later heading the Anti-Submarine Division at the Admiralty. In 1953, he was promoted to rear-admiral and served on the NATO staff.
Early life
Born in St George Hanover Square, Westminster, Clarence Johnston was the son of John Howard Johnston (1850–1913), an American from New Hampshire, and his wife Dorothy Florence Baird, of Scottish origins. Both the Johnston and Baird families were in engineering. He was brought up in Nice, France, and later adopted the name Howard-Johnston, appending his father's and his own middle name to his surname.
Howard-Johnston's father died in 1913, and his mother remarried, becoming Comtesse Pierre du Brevil de St Germain. He entered the Royal Naval College, Osborne, in 1917, and proceeded to the Royal Naval College, Dartmouth, as a cadet. His obituary in The Times says he first went to sea in 1922 as a midshipman.
Career
The sources differ regarding Howard-Johnston's early career, with The Times saying he spent some time on secondment in France and then was posted to China as second-in-command of HMS Tarantula while another source says that he was a lieutenant in 1925 when he served in Tarantula on the Yangtze river.

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
