Albert Pierrepoint (1905–1992) was the most prolific British hangman of the twentieth century, executing 434 men and women between 1932 and 1955. This table records the locations of each of the executions he participated in, the numbers in brackets being the number of executions he was assistant executioner at (often assisting his uncle, Thomas Pierrepoint), the other numbers are those in which he officiated as chief executioner. Apart from his work within the United Kingdom, Pierrepoint also conducted executions at Dublin's Mountjoy Prison in the Irish Free State and the later Republic of Ireland; for the British colonial authorities in Gibraltar; in the Suez Canal Zone, Egypt; at Graz-Karlau Prison in Austria; and most famously in the British occupation zone of Germany, at Hamelin, where he executed 156 Nazi war criminals. Locations Notable executions Second World War A total of 156 German war criminals executed between 1945 and 1949, following a series of war trials e.g. the Hamburg Ravensbrück Trials (16 executions between 1947 and 1949) and the Stalag Luft III murder trials, which resulted in 13 executions on 27 February 1948. The list of condemned includes Juana Bormann (Auschwitz); Irma Grese, the youngest concentration camp guard to be executed for crimes at Bergen-Belsen concentration camp and Auschwitz (aged 22); and Elisabeth Volkenrath (Bergen-Belsen and Auschwitz); plus another ten men including Josef Kramer (Camp Commandant at Belsen) and Fritz Klein, plus Georg Otto Sandrock and Ludwig Schweinberger, who had both been condemned for murdering Pilot Officer Gerald Hood of the RAF (while Hood was a POW) at Almelo, Netherlands, on 21 March 1945. Of the 13, 11 were condemned at the Belsen Trial and two others (Sandrock and Schweinberger) at a separate trial in Almelo. All were subsequently executed on the gallows in a purpose-built room at Hamelin Prison on 13 December 1945 at roughly half-hour intervals. The women were hanged individually, the men in pairs. The first execution started at 9.34 am and the last was completed by 4.17 pm. Executing a large number of war criminals in a single day was not unusual for Pierrepoint. For example, he performed the following eleven executions at on 8 October 1946, which resulted from the Neuengamme War Crimes Trial earlier the same year: Adolf Speck Alfred Trzebinski Andreas Brems Anton Thumann Bruno Kitt Heinrich Ruge Johann Reese Max Pauly Wilhelm Dreimann Wilhem Bahr Willy Warnke Others Gordon Cummins, the "Blackout Ripper":
