About Robert Liversidge
Lived 1904 – 1994 (aged 90). Robert Liversidge was a businessperson.
Robert William Liversidge (11 June 1904 – 30 September 1994), formerly Jacob (Jack) Perlsweig, was a British businessman whose activities sometimes attracted the attention of the police and intelligence services. He was also a reputed spy and the subject of a cause célèbre as an internee in Britain during the Second World War.
Early life Liversidge's parents, Asher Perlsweig, a rabbi, and Sarah, were Jewish immigrants to Britain from Russia. He was born in Harringay, London, one of five brothers and three sisters. He left school at the age of 14 and drifted before becoming involved in financial services. In July 1928 two of his associates, David and Dore Baumgart, were tried at the Old Bailey for conspiracy to defraud over share dealings in which Liversidge was also alleged to have been involved. An arrest warrant was issued for him, but it was never executed. He subsequently admitted that he had become involved with some dishonest people, but he always denied being guilty of any wrongdoing.
Some time before 1931 he adopted the name Liversidge (the married name of his eldest sister). In 1931 he applied for a Canadian passport in that name, claiming to have been born in Toronto and misstating his date of birth. He eventually managed a Hollywood recording studio, meeting a minor actress, Wanda Stevenson, and marrying her in 1936.
Liversidge returned to Britain in 1936, and became a wealthy and successful businessman. He legally changed his name to Liversidge in September 1937. However, his return was brought to the attention of the police by an informer and, although the arrest warrant from 1928 had been withdrawn in 1933, his Canadian passport was confiscated.
Defence Regulation 18B, which had been imposed at the start of the war, authorised internment. In early 1940 MI5 received intelligence that "three notorious Jew swindlers" were using "improper pressures brought to bear in High Places" to effect the release of internees from a camp at Seaton, Devon in return for payment of £500 (about £17,700 at 2003 prices). Thwaites was implicated, Liversidge was investigated, and the falsehoods about his birth were revealed. Liversidge was arrested on 26 April and charged with making a false statement. His flat was searched and the names of other persons known to the intelligence services were discovered. When he was interviewed it came to light that Liversidge had previously been Jack Perlsweig.
Allegations There seems to have been no evidence that Liversidge had "hostile associations" or had committed "acts prejudicial" to public safety. However, on 15 May the Secretary of State for Air, Sir Archibald Sinclair, wrote to the Home Office recommending that Liversidge be interned because "I am certain that you will agree that it is most undesirable that a man with the unsavoury and indeed dangerous associations of Perlsweig, who during recent months has had access to information of a most secret character, should be left at large either in the Service or in the Country."
The Reasons for Order served on Liversidge on 2 October alleged "hostile associations" only in count 7:
Liversidge's lawyers demanded particulars of these associations, but were refused. The more detailed Statement of Case asserted that Liversidge had "a very bad record," and referred to the Baumgart case and the Canadian passport application. It then alleged, on the word of the informant from 1937, that Liversidge had used the alias "John Stone" and had been involved in a fraud in New York City. The New York police had shown no interest in pursuing the matter through extradition. The Statement also claimed that Liversidge was an "associate" of Van Lighten, and alleged that he was involved, with a Leon Nussbaum and an interned German national named Richard Markus, in dubious dealings in industrial diamonds.
The Statement concluded:
Appeal
Liversidge sued for false imprisonment and the Crown filed a defence that he was lawfully detained under an 18B order. Liversidge then filed an application that the Crown disclose the grounds upon which the order was made, pleading that the Reasons for Order were insufficient. The application was dismissed by the High Court, as was an appeal to the Court of Appeal, and the case was brought to the House of Lords, joined with an appeal from another internee, Ben Greene. By a majority decision the Law Lords deferred to ministerial discretion on matters of national security in wartime. The application for disclosure was refused and Liversidge's internment was confirmed.
Release and later life On 9 November 1941, six days after the House of Lords issued its ruling, it was decided that there were no longer compelling reasons for Liversidge's detention. Liversidge was released on 31 December. Liversidge then joined the National Fire Service. After the war he became hugely wealthy through his continued business dealings. In 1948 he was called before the Lynskey Tribunal, as a friend of John Belcher, but he was exonerated of any misconduct. Until his death he remained bitter about his wartime treatment.
