The officials, side by side

Robert Anderson

Assistant Commissioner (CID) from 31 Aug 1888

View: A Polish Jew, identified by an eyewitness

In his words (1)
Historical text, verbatim:

In saying that he was a Polish Jew I am merely stating a definitely ascertained fact. And my words are meant to specify race, not religion.

Melville Leslie Macnaghten

Assistant Chief Constable (CID) from 1889

View: The murderer killed himself about 10 November 1888 (Druitt in the memorandum)

In his words (2)
Historical text, verbatim:

the probability is that, after his awful glut on this occasion, his brain gave way altogether and he committed suicide; otherwise the murders would not have ceased. The man, of course, was a sexual maniac, but such madness takes Protean forms, as will be shown later on in other cases. Sexual murders are the most difiicult of all for police to bring home to the perpetrators, for ''motives'' there are none; only a lust for blood, and in many cases a hatred of woman as woman. Not infrequently the maniac possesses a diseased body, and this was probably so in the 62 DAYS OF MY YEARS case of the Whitechapel murderer. Many residents in the East End (and some in the West !) came under suspicion of police, but though several persons were detained, no one was ever charged with these offences.

Historical text, verbatim:

I do not think that there was anything of religious mania about the real Simon Pure, nor do I believe that he had ever been detained in an asylum, nor lived in lodgings. I incline to the belief that the individual who held up London in terror resided with his own people ; that he absented himself from home at certain times, and that he committed suicide on or about the loth of November 1888, after he had knocked out a Commissioner of Police and very nearly settled the hash of one of Her Majesty's principal Secretaries of State.

Major (later Lt.-Col. Sir) Henry Smith

Acting Commissioner, City of London Police, 1888

View: No suspect; rejected Anderson's claim

In his words (3)
Historical text, verbatim:

There is no man living who knows as much of those murders as I do ; and before going farther I must admit that, though witliin five minutes of the perpetrator one night, and with a very fair description of him besides, he completely beat me and every pokce officer in London ; and I have no more idea now where he lived than I had twenty years ago.

From Constable to Commissioner: The Story of Sixty Years, Most of Them Misspent (Chatto & Windus, 1910), archive.org OCR text · From Constable to Commissioner (1910), p. 147 · Later recollection
Historical text, verbatim:

Since this chapter was written my attention has been drawn to an article in Blaclasoood's Magazine, of March this year — the sixth of a series by Sir Robert Anderson — entitled “ The Lighter Side of my Official Life.” In this article Sir Robert discourses on the Whitechapel, or Jack the Ripper, murders, and states emphatically that he, the criminal, “ was living in the immediate vicinity of the scenes of the murders, and that, if he was not living absolutely alone, his people knew of his guilt and refused to give him up to justice. The conclusion,” Sir Robert adds, “ we came to was that he and his people were low-class .Jews, for it is a remarkable fact that people of that class in the East End will not give up one of their number to Gentile justice, and the result proved that our diagnosis was right on every point.

Historical text, verbatim:

he accuses them of being accessories to these crimes before and after their committal. Surely Sir Robert cannot believe that while the Jews, as he asserts, were entering into this conspiracy to defeat the ends of justice, there was no one among them with sufficient knowledge of the criminal law to warn them of the risks they were running. [...] There is nothing “ light ” here ; a heavier indictment could not be framed against a class whose conduct contrasts most favourably with that of the Gentile population of the Metropolis. [...] are liable to penal servitude for life; and thus the Jews in the East End, against whom Sir Robert Anderson made his reckless accusation, come under that category.

Inspector Frederick George Abberline (CID, Scotland Yard)

Inspector, co-ordinating detectives on the ground, 1888

View: Kłosowski (George Chapman), as reported

  • Interview, Pall Mall Gazette, 1903 (reported, not a memoir) quoted (public domain)
In his words (2)
Historical text, verbatim:

"You can state most emphatically," said Mr. Abberline, "that Scotland Yard is really no wiser on the subject than it was fifteen years ago.

Pall Mall Gazette, 31 March 1903 - second Abberline interview (Casebook transcription) · PMG 31 Mar 1903 · Later recollection
Historical text, verbatim:

The fact that he studied medicine and surgery in Russia before he came here is well established, and it is curious to note that the first series of murders was the work of an expert surgeon, while the recent poisoning cases were proved to be done by a man with more than an elementary knowledge of medicine.
