Jean Knox



Jean Marcia Montagu, Baroness Swaythling, CBE (née Leith-Marshall; 14 August 1908 – 13 December 1993), first married name Knox, was Director of the Auxiliary Territorial Service from July 1941 to October 1943.

Early life
She was born on 14 August 1908 to G. G. Leith-Marshall. Before World War II, she lived in Leicestershire and was a housewife. She had had no other job pre-war.

Military service
Knox joined the Auxiliary Territorial Service nearly a year before the outbreak of World War II, in October 1938, and undertook kitchen duties. She became a company commander, in the 2nd Herts Company. On 30 May 1941, she was given a commission in the ATS in the rank of second subaltern, equivalent to second lieutenant. In April 1941, she was promoted to senior commandant (equivalent to major) and appointed Inspector of the ATS. In that role, she inspected every ATS command and had a seat on the ATS Council. On 21 July 1941, she was appointed Director, Auxiliary Territorial Service. She was given the acting rank of chief controller (equivalent to major general), while holding the war substantive rank of senior commander (equivalent to major). This made her the world's youngest general at that time. One of her first actions as Director was to design a new, well fitting uniform for all ranks of the ATS. On 21 July 1942, she was promoted to war substantive controller (equivalent to colonel) and made temporary chief controller. She travelled to Canada in September 1942 to inspect the Canadian Women's Army Corps and assisted in its recruiting campaign. She returned to the UK in November following the seven-week trip. On 30 October 1943, she relinquished the appointment of Director, Auxiliary Territorial Service, for health reasons.

On 12 December 1943, she relinquished the temporary rank of chief controller and relinquished her commission, thereby retiring in the rank of war substantive controller.

Later life
For six weeks in 1948, Knox was managing director of Peter Jones, Sloane Square, Chelsea, London. She gave no reason for her resignation in April 1948, but the department store described her appointment as a 'trial run'.

Knox died on 13 December 1993, aged 85.

Personal life
In 1935 she married S/Ldr. George Ronald Meldrum Knox son of Lt.-Col. James Meldrum Knox, with whom she had one daughter. They were divorced before 1945. In 1945, she married Stuart Albert Samuel Montagu, 3rd Baron Swaythling, in Southampton.
