Vice-Admiral Sir Michael Culme-Seymour, 4th Baronet, KCB, MVO (29 August 1867 – 2 April 1925) was a member of a substantial naval dynasty. He served during the First World War, commanding a ship at the Battle of Jutland in 1916. He received a number of awards and decorations, and served as Commander-in-Chief of the Mediterranean Fleet during the inter-war period, and as Second Sea Lord. He inherited a baronetcy on the death of his father, but died shortly afterwards with the rank of Vice Admiral.
Culme-Seymour was born on 29 August 1867, eldest son of Captain Michael Culme-Seymour and Mary Georgiana Watson.
He followed his father by embarking on a naval career and had risen to Captain by the outbreak of the First World War. He commanded the battleship HMS Centurion as part of the 2nd Battle Squadron of the Grand Fleet, and fought at the Battle of Jutland in 1916. He was Mentioned in Despatches for his efforts, and was promoted to Rear Admiral later that year.
Culme-Seymour spent the period between 1916 and 1918 as Director of Mobilization at the Admiralty.
For his service during the war he received a number of foreign honours. He was made a member of the Russian Orders of Saint Stanislaus (1st Class) and the Order of St. Vladimir (4th Class with swords), the Japanese Order of the Rising Sun (2nd Class), the French Légion d'Honneur and a Grand Commander of the Greek Order of the Redeemer.
With the end of the war Culme-Seymour became Commander of the 4th Battle Squadron in January 1919 and then the Commander-in-Chief, East Mediterranean Squadron in October 1919, with promotion to Vice Admiral on 7 October 1920.
The death of his father that year led to his succession as 4th Baronet Seymour, of High Mount.
He then became Commander-in-Chief of the North America and West Indies Station between 1923 and 1924, after which he became Second Sea Lord.
He died on 2 April 1925.
He had married Florence Nugent in 1896, and was succeeded by his wife and their son and daughter. The son, Michael, inherited the baronetcy and went on to serve in the Navy during the Second World War.
