Frederick Abberline
Metropolitan Police inspector
The CID officer English readers most often meet. He worked the ground in 1888 and later gave interviews that fed, but did not close, the suspect literature.
The dead were adult women with names. The living file is officers, a vigilance chair and later memoirists.
Suspect names in folklore are omitted here unless they appear in dated official paper.
People
Sir Charles Warren
Commissioner, Metropolitan Police
Resigned 8 November 1888 after a bruising autumn of press and Home Office conflict. His resignation is a political fact, not evidence of a hidden culprit.
Sir Robert Anderson
Assistant Commissioner, CID
Later wrote that the killer had been identified as a Polish Jew, a claim historians treat as memoir, not as a charging decision. No trial followed.
Sir Melville Macnaghten
Assistant Chief Constable (from 1889)
Not on the 1888 murder teams. His February 1894 memorandum created the canonical five and the Druitt–Kosminski–Ostrog triad that still structures amateur debate.
George Lusk
Whitechapel Vigilance Committee
A local builder who chaired a citizen patrol and received the “From Hell” letter. He stands for the civil, not Scotland Yard, half of the 1888 response.
Thomas Bond
Police surgeon
Wrote to Anderson on 10 November 1888 linking the canonical victims in a medical opinion. Later writers used that letter as glue; it was not a conviction.
Officers left paper. The killer left no name that a court would take.
Public-record encyclopedia. Not legal advice. Not a how-to. Graphic detail is withheld. Wars belong in a separate atlas.
