World War I a special execution room and cell for the condemned criminal was built. Strangeways was one of the few prisons to have permanent gallows. The first execution at Strangeways was that of twenty-year-old murderer Michael Johnson, who was hanged by William Calcraft on 29 March 1869. Twenty-nine hangings took place over the next twenty years and 71 took place in the 20th century, bringing the total number to 100. During the second half of the century, the number of executions decreased, with no hangings between 1954 and 28 November 1962, when James Smith was executed. John Robson Walby (alias Gwynne Owen Evans), one of the last two people to be hanged in England, was executed here on 13 August 1964. Out of the 100 hangings, four were double hangings, while the rest were done individually. The "quickest hanging" of James Inglis, in seven seconds, carried out by Albert Pierrepoint, took place here. Other executions John Jackson was executed on 7 August 1879. Mary Ann Britland (38) was executed on 9 August 1886 for the murder of two family members and her neighbour. She was the first woman to be executed at the prison. Thom Davies was hanged on 9 January 1889 for sexual deviancy charges. Lieutenant Frederick Rothwell Holt was hanged on 13 April 1920 for the murder of twenty-six-year-old Kathleen Breaks. Louie Calvert was hanged on 24 June 1926. Doctor Buck Ruxton was executed on 12 May 1936 for the murder of his wife. A petition for clemency was signed by 10,000 people, both sympathetic locals with high regard for this "people's doctor" and abolitionists who mounted a large demonstration on the day of his execution. Margaret Allen was hanged on 12 January 1949 by Albert Pierrepoint for the murder of an elderly widower. Her execution was the first of a woman in Britain for twelve years and the third execution of a woman at Strangeways. After the seven second hanging, Albert Pierrepoint executed Louisa May Merrifield on 18 September 1953. She was the fourth and last woman to be executed at the prison. The bodies of executed criminals were buried in unmarked graves within the prison walls, as was the custom. During prison rebuilding work in 1991, the remains of 63 executed prisoners (of which 45 were identifiable) were exhumed from unmarked graves in the prison cemetery and cremated at Blackley Crematorium in Manchester.
