Albert was one of the most prolific hangmen in history. There is no official tally of exactly how many executions he was involved in, but the BBC lists the number as anywhere up to 600 executions over his 25-year career. He was always perfectly professional in his demeanour and work, holding himself to incredibly high standards of behaviour and practice. He gained a reputation for being extremely accurate with his calculations, rarely failing to kill the prisoners he executed instantly, even in difficult circumstances.
