The Trust is named after Alexander Duckham, who founded Duckham's Motor Oils in 1899. As well as being a successful businessman, Alexander Duckham was an early aviation pioneer and close friend of cross-channel aviator Louis Bleriot.
Duckham generously donated his home, Vanbrugh Castle, to the Royal Air Force Benevolent Fund for use as a school for boys whose fathers had been killed in the First World War. Vanbrugh Castle was later sold after the number of pupils declined. On 1 September 1997, The Alexander Duckham Memorial Schools Trust was established by a Charity Commission Scheme.
The Scheme was amended in February 2010 to permit the Trust to promote the education and welfare of RAF children, of any age, in need.
