Captain Cyril Percy Ryan, C.B., Royal Navy, Retired (4 December, 1874 – 20 May, 1940) served in the Royal Navy.

Life & Career

Ryan was born in Kilkenny, the son of Lieutenant-Colonel E. Ryan.

Ryan took his entrance exams with the Britannia term of March, 1889, ranking ninth in order of merit in a small field of fourteen successful candidates, but apparently joined on 15 July.[1]

Ryan was promoted to the rank of Lieutenant in June, 1898.[2]

On 17 July, 1906, Charles Beresford, the Commander-in-Chief, Mediterranean reported that Ryan had been "of great service in experimenting with W/T in Destroyers & is an excellent all-round officer." Ryan was allowed to take out a patent for an Electric Life Buoy Release apparatus he had invented.[3]

Ryan was promoted to the rank of Commander in June, 1908.[4]

He was placed on the Retired List at his own request on 1 July, 1911.[5]

Great War

In Autumn of 1914, Ryan was put to work at Hawkcraig, developing Hydrophones for use in submarine detection. His first models were shore-based installations for controlling minefields.[6]

On 18 February, 1915, he was appointed to work with the Hydrophone Service.[7] The Annual Report of the Torpedo School for that year cited a hydrophone he'd developed for shore-based installations as being the most satisfactory model yet produced. His memorandum on the device noted that it was easier to hear a submerged submarine at a given horsepower than a surfaced one, that iron ships were more easily heard than wooden ones, and that paddlewheelers were easiest to ignore/reject.[8]

Ryan was promoted to the rank of Acting Captain on 1 October, 1916, and re-appointed with the Hydrophone Service.[9]

On 1 April, 1917, he was appointed to Tarlair, additional to lead the Hawkcraig Experimental Station, Aberdour. A considerable number of Lieutenants R.N.V.R. fell under his command in this post.[10]

Ryan was promoted to the rank of Captain on 14 December, 1919.[11]

Though Tarlair it may have moved on from Hawkcraig in mid-1919, Ryan remained in Tarlair until 5 January, 1920 when he was sent to Vernon for the Mining School, where he ran the Hydrophone Service until being superseded on 30 June, 1921.[12]
