Between 1857 and 1876, Newham oversaw the hanging of 24 inmates (all of them murderers) including that of Frances Kidder in 1868. Kidder (25) was found guilty of drowning her 12-year-old step-daughter, Louisa Staples, in 12 inches of ditch water. Following a change in attitudes and the law, she became the last woman to be publicly executed in England. Less severe punishments included flogging (usually up to 20 lashes applied) and solitary confinement, as well as the daily routine of a six-hour shift spent on the treadmill for those prisoners set to hard labour.
