About Denis Thatcher
Sir Denis Thatcher, 1st Baronet, was an English businessman and the husband of Margaret Thatcher, who served as the first female British prime minister from 1979 to 1990; thus, he became the first male prime ministerial spouse. Thatcher was granted the Thatcher baronetcy in 1990, the only baronetcy created since 1964, and remains the most recent non-royal to have been awarded a hereditary title. His MBE was gazetted on 20 September 1945, and was awarded for his efforts in initiating and supporting Operation Goldflake, the transfer of I Canadian Corps from Italy to the north-west European theatre of operations. On 21 September 1982 he was awarded the Territorial Decoration (TD) for his service.
