Albert Pierrepoint (1905–1992) was the most prolific British hangman of the 20th century, executing 435 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 over two hundred Nazi war criminals.
