John George Haigh was hanged at Wandsworth Prison on August 10, 1949, for the murder of Olive Durand-Deacon, a 69-year-old widow who lived at the same South Kensington hotel as he did. A jury at Lewes Assizes in Sussex had found him guilty on July 19 after a two-day trial, rejecting a defense that he was insane. That killing is the only one for which he was ever charged, tried or convicted.
The case is known for what he told the police. In a statement taken on February 28, 1949, he admitted killing Mrs. Durand-Deacon and five other people he knew, and he claimed three more killings that were never confirmed. He said he had destroyed the bodies in drums of sulphuric acid. He also said he had drunk his victims' blood, a claim the prosecution read to the jury and that the defense used to argue he was mad. The jury did not accept it. The five admitted deaths of William, Donald and Amy McSwan and Archibald and Rosalie Henderson are attributed to him in the Metropolitan Police file on the case, which The National Archives now holds, but none of them came before a court.
Haigh was born in 1909 in Stamford, Lincolnshire. His parents, John Robert and Emily Haigh, belonged to the Plymouth Brethren, a strict Protestant group, and he was their only child. The family moved to West Yorkshire and lived on Ledger Lane in Outwood, near Wakefield.
Accounts of his childhood describe a closed house. The historian Gordon Lowe writes that his parents built a seven-foot fence around it; Lincolnshire Life, in a 2015 profile, gives the fence as ten feet and says he was not allowed to play with other children and spent his time with his pet rabbits. He later said that his parents' religion had given him nightmares.
He was a capable pupil. He won a scholarship to Queen Elizabeth Grammar School in Wakefield, the Yorkshire Evening Post reported, and became a chorister at Wakefield Cathedral; Lincolnshire Life adds that he served at the altar there and was made assistant organist while still at school. Fellow choristers remembered him, the Evening Post reported, as "a brainy lad, but a bit of a loner." After his death someone sent the Wakefield Express a photograph of him as a smiling choirboy.
After school he went through a series of short-lived jobs. He then set up on his own, forging vehicle documents and selling cars that did not exist, according to Lincolnshire Life. The fraud came to light in 1934 and he was sent to prison. On his release in 1936 he moved to London, where his family cut him off.
In London he went to work for the McSwan family. William McSwan ran amusement businesses, and Haigh became his chauffeur and collected the rents on the family's properties. William liked him and once called him "charming," the Alloa and Hillfoots Advertiser reported in a 2019 history of the family.
Haigh did not stay out of trouble. He set himself up as a solicitor without any legal qualification, was arrested, and spent the next few years in and out of prison, Lincolnshire Life records. The Yorkshire Evening Post describes several more sentences for fraud.
It was in prison, by the account in Lincolnshire Life, that he first thought about acid. In 1941, while he was held at Lincoln Prison, he planned a killing in which the body would be dissolved. He took sulphuric acid from a prison workshop, had prisoners who worked on the prison farm bring him mice, and experimented on them. He believed that if there was no body there could be no conviction. The same idea runs through every later account of the case. Lowe puts it in one line: Haigh's theory was that with no body there was no crime.
William Donald McSwan was born on May 12, 1911, the only child of Donald McSwan and his wife Amy. His father came from Clackmannanshire in Scotland, which is why the Alloa and Hillfoots Advertiser told the family's story in 2019. William left home in 1932 and started a string of small businesses: a pin-table business called Automatics in 1934, then an amusement arcade and a sweet shop in 1938. He sold the shop the next year and closed the pin-table business. From 1941 he worked as a salesman for the Henderson Tank Company and then for Art Magazine Engineers, and he rented premises for a welding business, doing its office work himself.
He did not want to go to war. Within a year of the outbreak of war in 1939 he registered as a conscientious objector. Call-up papers came in 1941 with a six-month deferment. The Advertiser reports that he was deeply afraid of being sent to fight and moved from place to place to keep out of the authorities' way.
In 1944 Haigh rented three basement rooms at 79 Gloucester Road in Kensington and moved in on September 6. On Saturday, September 9, William told a colleague, a Mr. Woodsman, that he was going away for the weekend. He met Haigh at The Goat, a pub on Kensington High Street, and went with him to the basement. He was never heard from again.
In February 1949 Haigh told police he had hit William on the head with a cosh, that he had died within about five minutes, and that he had then destroyed the body with sulphuric acid and poured what remained down the drain. He kept William's valuables. To explain the disappearance he wrote to William's parents as if he were their son, telling them William was keeping out of the way of the call-up and dealing in property.
No charge was ever brought for William McSwan's death. What is known of it comes from Haigh's own statement, as reported in the press and summarized in the 2019 Advertiser history, and from the Metropolitan Police file, which includes a photograph of William among its records.
Donald McSwan was born in June 1878 at Glenochil Cottages near Menstrie, in Clackmannanshire. By 1901 he was a clerk at the Glenochil Distillery. He took an evening class in shorthand and typing, moved to England in 1908, and by 1929 was working as a shorthand typist at the Shoreditch Technical Institute in London. He met his wife, Amy, whom the family called Sarah, while she was working at the Spa Hotel in Tunbridge Wells, Kent, and they married in October 1910. After the First World War they moved to London. They bought several houses, which they let, while renting the homes they lived in themselves.
In the summer of 1945 Haigh was under notice to leave the Gloucester Road basement by July 6. Donald McSwan was last seen alive on July 2, 1945. He had told Mr. Woodsman that he was hoping for a call from his son, which struck people as unusual. Haigh later admitted killing Donald and Amy separately in the basement and disposing of their bodies in the same way. Police believed an axe had been used; Haigh insisted it was the cosh. The 2019 Advertiser account dates the deaths to July 2, the last day Donald was seen.
Haigh then took over what the family owned. Posing as William, he obtained a power of attorney in Glasgow and used it to sell the McSwan properties, and he drew money from the family's bank accounts in monthly installments. The Advertiser puts his gain at more than 5,000 pounds. He lived on it, and gambled it away, over the next two years.
Neither Donald nor Amy McSwan's death was charged or tried. Both are attributed to Haigh on the strength of his own admission.
With the McSwan money Haigh lived well. By 1947 he was living at the Onslow Court Hotel in Kensington, Lincolnshire Life reports, and renting a workshop in Crawley, Sussex, where he kept his acid and his drums. Lowe describes a man who had his suits made on Savile Row, drove an Alvis, and presented himself as a civil engineer and inventor. The workshop was on Leopold Road in the West Green area of Crawley.
He had a girlfriend of five years who intended to marry him and knew nothing of what he had done, Lowe writes.
In Crawley people remembered him. Ron Shaw, who ran Shaw's Garage on Orchard Street, recalled his expensive sports cars and that he had gone around town asking for a tub that could hold acid, the Sussex Express reported in 2017. Haigh stayed at the Gatwick Hall Hotel at Lowfield Heath in early 1948. A Crawley optician, Thomas Cripps of Bateman's on the High Street, kept a letter Haigh sent him dated March 1, 1948, asking for his glasses to be repaired.
By early 1948 the McSwan money was running short, and Haigh turned to Dr. Archibald Henderson and his wife Rosalie. The National Archives holds a photograph of the couple, filed as "Dr Archibald and Mrs Rosalie Henderson," among the Metropolitan Police records of the case. Little else has been reported about them as people beyond the doctor's profession and their money.
Haigh later admitted that early in 1948 he shot Dr. Henderson and then Mrs. Henderson at the Crawley workshop, destroyed their bodies with acid, and forged letters so that he could take their assets, according to the Alloa and Hillfoots Advertiser and Lincolnshire Life.
The Sussex Express recorded one sighting from that winter. In January 1948, it reported, Haigh and Dr. Henderson called at Broadfield House, a closed country club and hotel near Crawley that was about to become a planning office. Jack Cook answered the door. Haigh asked to use the telephone, paid two shillings for the call, and said he would be at the Punch Bowl Restaurant in Crawley. Cook's daughter later wrote that Dr. Henderson was believed to have been killed that night. That date does not match the February 1948 date given in other accounts, and the point is set out under Disputed and unproven points below.
The Hendersons' deaths were never charged or tried. They rest on Haigh's statement to police and on the papers and property that linked him to the couple.
Olive Durand-Deacon was 69 and a widow, and she lived at the Onslow Court Hotel. Lowe describes her as a kindly and talented woman, a former suffragette and the widow of a war hero; the Alloa and Hillfoots Advertiser describes her as the wealthy widow of a solicitor. The Reuters report of the Daily Mirror contempt case in March 1949 described her as a wealthy elderly widow who had disappeared from her London hotel.
She had an idea for a business. She wanted to make artificial fingernails and talked to Haigh, the hotel's resident engineer and inventor, about patenting them, Lowe writes. Haigh offered her his workshop.
On February 18, 1949, he drove her to Crawley. At the workshop on Leopold Road he shot her and put her body into acid. He took her valuables. He sold her jewelry and had her fur coat cleaned, Lowe writes. Ron Shaw, the Crawley garage owner, later remembered a light burning in Haigh's workshop on what he took to be that night.
Her death is the only one in this case that a court has examined. A jury found Haigh guilty of her murder on July 19, 1949.
Mrs. Durand-Deacon had a close friend at the hotel, and the friend noticed she was gone. Haigh then took the friend to the police himself to report Mrs. Durand-Deacon missing, Lowe writes. A police sergeant who dealt with them did not like his manner. Lincolnshire Life says the police looked into the hotel's residents, found Haigh's record and obtained a warrant to search his workshop.
At Crawley they found a metal drum, containers of acid, a wartime revolver and an apron and gloves splashed with acid, according to Lowe. The revolver, he writes, had been taken from an earlier victim. In an attache case police found a dry cleaner's receipt for Mrs. Durand-Deacon's coat, and they learned that he had sold her jewelry. The Sussex Express noted that the cleaning receipt helped lead to his arrest. After the arrest, detectives questioned many people in Crawley who had met him.
On February 28, 1949, police brought Haigh in for questioning while they searched his hotel room and his workshop. The National Archives holds his statement from that day in the Metropolitan Police file, MEPO 3/3128, which the catalogue describes as concerning mass murders committed by Haigh at South Kensington and Crawley, with the bodies of six victims dissolved in sulphuric acid at Crawley. That catalogue title records the police view of the case; it is not a court finding.
Detective Inspector Albert Webb questioned him.
He then admitted the killing of Mrs. Durand-Deacon and of five others, the three McSwans and the two Hendersons. He claimed three more killings as well; detectives were never able to prove them, the Yorkshire Evening Post reported. In all, the Associated Press reported in 1949, he told police he had killed eight people besides Mrs. Durand-Deacon. He also said he had drunk their blood. That claim led some newspapers to call him the "Vampire Killer."
Gordon Lowe's 2015 book, according to its publisher, asks whether the blood-drinking story was true at all, or whether it was a calculated attempt to be sent to Broadmoor rather than to the gallows.
Haigh had believed he had destroyed the evidence. At Gloucester Road, by his own account, the remains had gone down a drain. At Crawley there was no drain to use, and the waste from the drums had been thrown into the yard outside the workshop, the Law Society Gazette's review of Lowe's book notes.
The Home Office pathologist Keith Simpson examined the sludge. In it he found human gallstones, part of a denture, bone fragments and the remains of Mrs. Durand-Deacon's red plastic handbag, according to Lowe. The dentures were identified at the trial by a dentist, and the Yorkshire Evening Post called them crucial to the case. The gallstones, gloves and apron are among the objects kept in the Metropolitan Police's Crime Museum, the Associated Press reported in 2015.
Simpson later published an account of the medical evidence, "Rex v. John George Haigh, the Acid-Bath Murder," in the Medico-Legal Journal in 1950.
Haigh was charged with the murder of Olive Durand-Deacon about two days after he was first questioned, the Alloa and Hillfoots Advertiser reports. He was never charged with any other killing.
He first appeared before magistrates at Horsham, Sussex, where the court then sat in the old town hall in Market Square. Crowds gathered in the square and people queued for seats in the public gallery. A columnist for the County Times, writing as Old Mick in 1997, remembered the crowds that came for a glimpse of him. Between hearings Haigh was held in cell 2 at Horsham police station on Barttelot Road; the cell door is now in Horsham Museum, along with a comb he used in the prison hospital at Lewes, the Sussex Express reported.
Before Haigh was tried, his case led to a contempt ruling against the Daily Mirror. In March 1949 the paper published reports that portrayed him as a vampire and described other killings he was said to have committed, while he was charged with one murder and had been convicted of nothing.
On March 25, 1949, the High Court in London fined the paper's proprietors, Daily Mirror Newspapers Limited, 10,000 pounds for contempt of court and ordered its editor, Silvester Bolam, to be held in Brixton prison for three months, Reuters reported. The Lord Chief Justice, Lord Goddard, said there had never been a case of contempt approaching it in gravity. He called the article "of a scandalous and wicked character" and said the paper had accused Haigh of murder after murder, giving lurid details of other killings when the man in custody was charged with one.
Sir Valentine Holmes, for the editor and the company, expressed their sincere and unqualified regret. Goddard said the publication was not a mere error of judgment but a matter of policy, pandering to sensationalism to increase circulation. He warned the company to take note of what their employees were capable of, and said that if anything like it happened again, the arm of the court was long enough to reach them.
The trial opened at the Sussex Assizes in Lewes on Monday, July 18, 1949, before Mr. Justice Travers Humphreys. Haigh, described by Reuters as a 39-year-old company director, pleaded not guilty to the murder of Mrs. Durand-Deacon.
The Attorney General, Sir Hartley Shawcross, led for the Crown. He told the jury that Haigh had lured Mrs. Durand-Deacon to a building in Crawley, where her body was partly dissolved in sulphuric acid, and that he had then tried to raise money from her belongings. Shawcross also told the jury that Haigh had told police he drank the blood of his victim, adding that the statement might or might not be true. The prosecution showed that Haigh had made several thousand pounds by selling his victims' property and that he had twice before served prison terms for fraud, a wire report published after his execution noted. Among the exhibits Shawcross put before the jury were the stained handbag, the gallstones and the dentures, the Law Society Gazette's review records.
The defense was led by Sir David Maxwell Fyfe.
Haigh did not deny that he had killed Mrs. Durand-Deacon. The issue for the jury was whether he was responsible for it. He did not give evidence in his own defense, the Associated Press reported.
The legal test was the M'Naghten Rules on insanity, and his claims of blood-drinking and dreams were aimed at meeting it, the Law Society Gazette's review of Lowe's book notes. Haigh's defense asked for the special verdict then available, guilty of the act charged but insane at the time.
Maxwell Fyfe argued that Haigh suffered from paranoia and could not tell reality from dreams. He told the jury Haigh dreamed of cups of blood that he could not reach until he killed a victim and drank, according to the wire report of the execution. The Law Society Gazette's review of Lowe's book says the defense also argued that Haigh may have believed he was acting under divine guidance.
The defense's medical witness was Dr. Henry Yellowlees, a psychiatrist. He told the court on July 19 that Haigh had gone beyond a paranoid constitution into a form of insanity, Reuters reported. Haigh sat back in the dock as he listened and now and then smiled. When the defense case closed, Shawcross called no evidence in rebuttal of Yellowlees, saying there was nothing to rebut.
What decided the case was Shawcross's cross-examination. Yellowlees accepted that Haigh had known that what he was doing was wrong. In Lowe's words, quoted in the Law Society Gazette: "once Dr Yellowlees admitted that this man knew he was doing wrong, that was an end to the case." Lowe's point is that, under the M'Naghten Rules, a defendant who knew his act was wrong could not succeed with the defense.
The jury, 11 men and one woman, went out on July 19 and returned in about 15 minutes, the Associated Press reported from Lewes that day. Other accounts give the time as 17 minutes or about half an hour. They found Haigh guilty of murder and did not return the special verdict of insanity. Mr. Justice Humphreys sentenced him to death. The Prison Commission's file on Haigh in The National Archives, PCOM 9/818, records that he was convicted at Lewes on July 19, 1949, of murder and sentenced to death.
Lowe adds a footnote about the judge: Travers Humphreys later retired to the Onslow Court Hotel, where Haigh had lived.
No appeal was lodged. Haigh was not reprieved.
He was held in the condemned cell at Wandsworth Prison. Lowe describes his last weeks. He had his hair cut by his barber. He stopped receiving visitors once he had to wear prison clothes. The day before his execution he sat for a life mask so that Madame Tussauds could make a wax figure of him, wearing clothes he had chosen. He asked to meet the hangman so that his weight could be checked; the prison governor told him that Albert Pierrepoint would account for it without a meeting. His parents believed that God would forgive him, Lowe writes.
Albert Pierrepoint hanged him at Wandsworth on the morning of Wednesday, August 10, 1949. He was 40. Officials alone witnessed the execution, a wire report said; the wire report carried by The China Mail gives the time as 9 a.m. Lowe writes that the whole operation, from cell to drop, took eleven seconds.
The Associated Press report of the execution called him a self-confessed killer of nine and noted that he had been convicted on July 19 of murdering Mrs. Durand-Deacon for her money.
John George Haigh died on August 10, 1949. His legal record is simple. He was convicted of one murder, that of Olive Durand-Deacon, and the conviction stood: no appeal was brought and he was executed. He was never charged with the deaths of William, Donald and Amy McSwan or of Archibald and Rosalie Henderson, so no court ever decided whether he killed them. Those five deaths are his admissions, supported in the police file by the papers and property of the victims that he held, and they are attributed to him on that basis. The three further killings he claimed have never been confirmed, and no victims have been identified for them.
The official records survive. The Metropolitan Police file, MEPO 3/3128, includes his statement of February 28, 1949, photographs of victims including William McSwan and the Hendersons, and photographic evidence. The Prison Commission file, PCOM 9/818, includes press cuttings from the Morning Advertiser and a copy of a shopping list connected to the case. Both are at The National Archives at Kew.
The objects from the case went to the Metropolitan Police's Crime Museum at Scotland Yard, known as the Black Museum. In 2015 the Museum of London showed items from it, including the leather gloves and apron Haigh wore and the gallstones found in the Crawley yard, the Associated Press reported in June 2015. Lowe writes that the revolver and the dentures were shown as well.
An account of the trial was published in 1953 as The Trial of John George Haigh (The Acid Bath Murder), edited by Lord Dunboyne, in the Notable British Trials series (William Hodge and Company). In 2002 Yorkshire Television dramatized the case as A Is for Acid, with Martin Clunes as Haigh and Keeley Hawes, the Yorkshire Evening Post noted. In 2015 The History Press published Gordon Lowe's The Acid Bath Murders, which its publisher says draws on unpublished archive papers and on letters Haigh wrote from prison while awaiting execution; the Law Society Gazette reviewed it.
Proven by a court: the murder of Olive Durand-Deacon on February 18, 1949. The Lewes jury's verdict of July 19, 1949, was not appealed, and Haigh was executed.
Admitted but never charged or tried: the deaths of William McSwan (1944), Donald and Amy McSwan (1945), and Archibald and Rosalie Henderson (1948). Several newspaper histories say he was convicted of six murders, or found guilty of all of them. That is wrong. He was tried for one.
Claimed and never confirmed: three further killings. Detectives could not prove them, and no victims were identified.
The blood-drinking claim: Haigh told police he drank his victims' blood. Whether he did was never established. The prosecution told the jury the statement might or might not be true, and the jury rejected the insanity defense built partly on it. Lowe's book treats the claim as possibly a calculated move toward Broadmoor.
Dates and figures that vary between sources:
The Hendersons: the Sussex Express (2017) gives a January 1948 sighting at Broadfield House on the night Dr. Henderson was believed killed; other accounts place the killings in February 1948. No reliable report fixes the exact date.
William McSwan: Haigh moved into the Gloucester Road basement on September 6, 1944; William disappeared on September 9. Some accounts give September 6 as the date of his death.
The jury's time out: about 15 minutes (Associated Press, July 19, 1949) or about half an hour (Lowe).
His gain from the McSwans: more than 5,000 pounds (Alloa and Hillfoots Advertiser); other accounts give larger figures.
The height of the fence around his childhood home: seven feet (Lowe) or ten feet (Lincolnshire Life).
Olive Durand-Deacon's late husband: a solicitor (Alloa and Hillfoots Advertiser) or a war hero (Lowe).
