It's already been answered several times Albert Pierrepoint, but I just wanted to add a few things , he didn't resign after hanging Ruth Ellis, although an honourable man he was devastated when he had to hang one of his old friends who had particularly asked for Albert to do it.
His official reason for resigning in 1956 was he was not paid for supposedly hanging someone who was reprieved and felt he should still have been paid at least his expenses.
My source is a clip of a recent film taken from his autobiography played brilliantly by Timothy Spall.
I remember reading about him a few years after he had hanged Timothy Evans in 1950 who was pardoned about 40 years later.
Pierrepoint prided himself in carrying out his duties as quickly and humanely as possible, which should put our American friends to shame regardless of your viewpoint on capital punishment.
His record from walking through the cell door to the prisoner being pronounced dead was seven and a half seconds.
