Brigadier-General Sir Wyndham Henry Deedes, CMG, DSO (10 March 1883 – 2 September 1956) was a British Army officer and civil administrator.

[1] He was the youngest son of East Kent gentry, Colonel Herbert George Deedes and Rose Elinor Barrow,[2] whose family had owned the land between Hythe and Ashford for four centuries.

[17] From 1920 to 1922, Deedes served as Chief Secretary to the then British High Commissioner Sir Herbert Samuel in Palestine.

Although Deedes had pro-Zionist sympathies, he played a role in promoting the Supreme Muslim Council as an Arab counterweight to the Jewish Agency.

[19] Upon returning to England, Deedes did not take up his heritage as a country squire, but moved to London and chose to do unpaid social work in one of the poorest quarters of the city.

When the London Turkish House (Halkevi) was set up during World War II to help foster Anglo-Turkish relations, Deedes was its chairman, with Lady Dorina Neave in charge of its social side.

[2] His older brother, Herbert William Deedes (born 27 October 1881), married Melesina Gladys Chenevix Trench on 3 July 1912.

[3] Deedes translated three major Turkish literary works into English: two novels by Reşat Nuri Güntekin and a memoir by Mahmut Makal:[23]
