Lizzie was the wife of royal physician Sir John Williams, himself seen as a prime suspect by many other crime experts.
Mr Morris, from Birmingham, also cites evidence - which has not proved popular among Ripper experts - including the fact that none of the five murdered prostitutes was sexually assaulted; and the personal items of one, Annie Chapman, were laid out at her feet 'in a feminine manner'.
The men sifted through thousands of medical and legal documents to draw up a compelling case for branding Lizzie the killer.
But John, speaking from his current home in Wicklow, Ireland, said their theory has not gone down well with Ripperologists.
'The case for a woman murderer is overwhelming. But unfortunately it does not sit well in some quarters where such a theory flies in the face of long-held beliefs,' he told the Birmingham Mail.
'There’s absolutely no doubt that the Ripper was a woman. But because everyone believes that the murderer was a man, all the evidence that points to a woman has always been ignored.'
The Ripper struck five times during a blood-soaked ten weeks in 1888. The victims - Mary Ann Nichols, Annie Chapman, Elizabeth Stride, Catherine Eddowes and Mary Jane Kelly - were all East End prostitutes.
Three had their wombs removed, which John believes is significant.
He says Welshwoman Lizzie, born on February 7, 1850, was unable to have children and, in an unhinged state, took terrible revenge on those who could.
Coroner Wynne Baxter said at Annie Chapman’s inquest: 'The conclusion that the desire was to possess the missing (body) part seems overwhelming.'
John also points to the facts:
None of the women was sexually assaulted;
Personal items were laid out at the feet of Chapman in, according to newspaper reports, ‘a typically feminine manner’;
Three small buttons from a woman’s boot were found in blood near Catherine Eddowes;
Remnants of women’s clothing - a cape, skirt and hat - were found in the ashes of Mary Kelly’s fireplace. Mary had never been seen wearing them
John believes there’s a reason Mary Kelly was targeted - and why the killing spree ended with her death.
Lizzie’s husband, Sir John, who ran abortion clinics in Whitechapel, was having an affair with her.
The author added: 'There are numerous clues scattered throughout the crimes which, taken individually, may mean little, but when grouped together a strong case for a woman murderer begins to emerge.'
Lizzie - nee Mary Elizabeth Ann Hughes - was the daughter of a Welsh industrialist Richard Hughes. The couple were married in 1872, when he was 32 and she was 22.
Soon after the grisly deaths, Lizzie suffered a nervous breakdown. She died of cancer in 1912, having never been quizzed by police over the murders.
