Sir Harold Augustus Wernher, 3rd Baronet, GCVO, TD (16 January 1893 – 30 June 1973)
He was the son of Sir Julius Wernher, 1st Baronet and his wife Alice Sedgwick Mankiewicz. On 20 July 1917, Harold married Anastasia de Torby (9 September 1892 Wiesbaden - 7 December 1977 London), the eldest daughter of Grand Duke Michael Mikhailovich Romanov and they had three children:
He reached the rank of major-general during World War II, and played an important role in coordinating the logistics of Operation Overlord.
In 1948, Harold inherited his baronetcy from his brother (who had no male heirs). He had previously inherited Luton Hoo upon his father's death. Harold died at Luton, Bedfordshire in 1973 and as he also did not have any surviving male heirs, the baronetcy became extinct.
