James Berry (8 February 1852 – 21 October 1913) was an English executioner from 1884 until 1891. Berry was born in Heckmondwike in the West Riding of Yorkshire, where his father worked as a wool-stapler. His most important contribution to the science of hanging was his refinement of the long drop method developed by William Marwood, whom Berry knew quite well. His improvements were intended to diminish mental and physical suffering and some of them remained standard practice until the abolition of capital punishment for murder.
An insight into Berry's behaviour and methods can be read in the book My Experiences as an Executioner, in which he describes his methods and recalls the final moments of some of the people he executed.
He served eight years with the Bradford Police Force, then tried himself as a boot salesman. Since he did not earn enough for the upkeep of his family, he applied for the post of executioner after William Marwood died in 1883 but was unsuccessful despite being shortlisted, until the short period of Bartholomew Binns in office was over.
Berry was the first British hangman literate and communicative enough to be able to write freely about his work. He considered that the hangman was the last link in what he called the "chain of legal retribution".
He was the executioner who failed to hang John Babbacombe Lee – "The Man They Couldn't Hang" – in 1885. The trap door repeatedly failed to open and Lee's sentence was commuted.
During the execution of Robert Goodale on 30 November 1885 at Norwich, the prisoner was given too long a drop so that the rope decapitated him.
Berry's time in office came to an end following interference in his judgement by the prison medical officer at Kirkdale Prison regarding the appropriate length of drop; Berry compromised but the condemned man John Conway was nearly decapitated. In March 1892 Berry wrote his letter of resignation, probably without knowing that in October of the previous year the Home Office had already decided that "the employment of Berry as Executioner should no longer be recommended to the High Sheriffs."
