Ritchie was born in Burnley, 1914, of Scottish parents, Sir Douglas Ritchie and Lady Margaret Stephen Ritchie. He was educated at the Royal Naval College, Dartmouth from the age of 13, from where he went to sea at the age of 17. In 1936 he joined the Surveying Service, being appointed to the old coal-burning surveying ship, HMS Herald, operating in the South China Sea.
From that time he worked continuously in that branch of the Royal Navy travelling all over the World and commanding four of HM surveying Ships: HMS Challenger on a world circling voyage with scientists on board; HMNZS Lachlan, the New Zealand survey ship; HMS Dalrymple, in the Persian Gulf and HMS Vidal in the West Indies and North Atlantic. In 1951 on the survey ship HMS Challenger, recorded the deepest part of the ocean trench depth Challenger Deep of 5,960 fathoms (10,900 m, 35,761 ft) using echo sounding. In 1966 he was promoted to the position of Rear Admiral and appointed to the post of Hydrographer of the Navy which he held for five years, responsible for the operations of the RN Surveying Squadron and the publication of the Admiralty Chart world-wide series. In 1967 he received a Companion of the Bath.
After 18 months as a Senior Research Fellow at Southampton University he was elected first in 1972 and again in 1977 as President of the International Hydrographic Bureau, thus spending 10 years in the Principality of Monaco, in the service of the then 50 Member States of the International Hydrographic Organisation.
Admiral Ritchie received the Founder’s Medal of the Royal Geographical Society, the Gold Medal of the Royal Institute of Navigation, the Silver Medal of the Royal Society of Arts and the Prix Manley-Bendall from the Academie de Marine. He was an honorary member of the Challenger Society for Marine Science and an Emeritus Member of the Hydrographic Society.
After his return from Monaco he lived with his wife, Disa, in the family house built by his grandfather in the fishing village of Collieston, Aberdeenshire. He published other titles including Challenger - The Life of a Survey Ship (1957), The Admiralty Chart (1967), No Day too Long (1992) and As it Was(2003). He wrote a regular column describing how hydrography used to be, for the international publication Hydro International from 1985–1995.
He died on 8 May 2012 in Collieston, Aberdeenshire.
