Thomas Joseph Kendrick (26 November 1881 - 3 March 1972) was a British intelligence officer, operating under the code name "Colonel Wallace".
[1] Austria was annexed to Germany in the Anschluss of March 1938 and on 17 August that year Kendrick was visiting Freilassing in Bavaria when he was arrested for espionage by the Sicherheitsdienst.
[2] In the months before his arrest, Kendrick came into contact with Adolf Eichmann, who was then in charge of negotiating the expulsion of Viennese Jews and their acceptance by the British Mandate of Palestine.
[3] During the Second World War Kendrick organised a unit to set up secretly-bugged "M-Rooms" (mike rooms), from which intelligence officers listened in on German prisoners-of-war in their bugged quarters and cells.
[5] In spring 1940 the Reichssicherheitshauptamt in Berlin assessed him to be a sensitive intelligence figure and he was thus placed on the Sonderfahndungsliste G.B., a list of those to be automatically arrested by the SS after a successful German invasion of Britain.
