Strange case of how 2 unrelated men with same name & identical looks sparked the need for fingerprinting in the US

The man on the left was called Will West, while the one on the right was called William West, and they were both sentenced to jail at Leavenworth Penitentiary in Kansas over 100 years ago.

Will West arrived at the same prison in 1903, two years after William West was imprisoned. His arrival caused the records clerk at the prison considerable confusion, because he was convinced he’d processed him two years previously.

The clerk, M.W. McClaughry, asked Will West if he’d ever been to the prison before. West said he hadn’t.

McClaughry then set about taking his Bertillon measurements – named after the French policeman Alphonse Bertillon – which was the usual method of identifying people and involved recording the dimensions of key physical features.

McClaughry, still convinced the man before him had already been to the prison, looked up his name in his filing system and found one William West – who looked identical to Will West in the photographs in every respect.

They even shared the same Bertillon measurements.

But Will West insisted to McClaughry that it was not him: ‘That’s my picture, but I don’t know where you got it, for I know I have never been here before.’

To McClaughry’s shock, he was absolutely right, too. William West was a different person altogether and in fact had been admitted to the prison two years previously for murder.
The case highlighted the flaws in the Bertillon method and it wasn’t long before the U.S authorities turned to fingerprinting.

Its pioneer was Scotland Yard’s Sgt. John K. Ferrier, who met McClaughry at the St Louis World Fair in 1904 while he was guarding the Crown Jewels, which were on tour.
He told the U.S prison officer how Scotland Yard had been using fingerprinting for the past three years and evangelised its accuracy.

McClaughry was sold, and after being instructed on the technique he introduced it to Leavenworth Prison. America’s first national fingerprint repository was established shortly afterwards.
