CaptainArchibald Henry Maule Ramsay (4 May 1894 – 11 March 1955) was a British Army officer who later went into politics as a Scottish UnionistMember of Parliament (MP). From the late 1930s, he developed increasingly strident antisemitic views. In 1940, after his involvement with a suspected spy at the United Statesembassy, he became the only British MP to be interned under Defence Regulation 18B.
Ramsay was from a Scottish aristocratic family; his grandfather was Sir Henry Ramsay, younger brother of George Ramsay, 12th Earl of Dalhousie. He attended Eton College and the Royal Military College, Sandhurst, joining the Coldstream Guards in 1913. After the outbreak of World War I, he served in France for two years. He received a severe head injury before being invalided out and transferred to the War Office in London. Here he met and married on 30 April 1917 Lady Ninian Crichton-Stuart, née Hon. Ismay Preston, daughter of Viscount Gormanston and widow of Lord Ninian Crichton-Stuart MP, who had been killed on active service in the war. His wife was the mother of three surviving children. The couple later had four sons together; the eldest died on active service in 1943.
As the war was coming to an end, Ramsay served at the British War Mission in Paris. He retired from the Army with the rank of captain in 1920. He spent the 1920s as a company director, near Arbroath, Angus, and became active in the Conservative Party. In the 1931 general election, Ramsay was elected as MP for Peebles and Southern Midlothian. He was not considered a potential candidate for high office; the most senior appointment he obtained was as a Government member of the Potato Marketing Board.
