Context paragraphs:
Arthur Wilson (Royal Navy officer): Admiral of the Fleet Sir Arthur Knyvet Wilson, 3rd Baronet (4 March 1842 – 25 May 1921) was a Royal Navy officer.  He served in the Anglo-Egyptian War and then the Mahdist War being awarded the Victoria Cross during the Battle of El Teb in February 1884.  He went on to command a battleship, the torpedo school HMS "Vernon" and then another battleship before taking charge of the Experimental Torpedo Squadron.  He later commanded the Channel Fleet.  He briefly served as First Sea Lord but in that role he "was abrasive, inarticulate, and autocratic" and was really only selected as Admiral Fisher's successor because he was a supporter of Fisher's reforms.  Wilson survived for even less time than was intended by the stop-gap nature of his appointment because of his opposition to the establishment of a Naval Staff.  Appointed an advisor at the start of World War I, he advocated offensive schemes in the North Sea including the capture of Heligoland and was an early proponent of the development and use of submarines in the Royal Navy.

He was involved in some way in the design or construction of five of the first six U.S. Navy aircraft carriers, and served as acting commanding officer of the first carrier to enter U.S. Navy service and as executive officer of the first two American carriers.  In the earliest days of the U.S. Navy' s development of an aircraft carrier force, he led many shipboard innovations still in use aboard carriers today.
