An unknown person nicknamed "Jack the Ripper" (fl. 1895)[1] was a serial killer in the 1800s, operating in Victorian London.



In Victorian London, Vandal Savage received tutorage from Jack on how to surgically dissect a human body.[2]

According to Nate Heywood, Jack went on a killing spree in the Whitechapel district of London in around 1895.[1] Although there were some suspects, the identity of Jack the Ripper remained unsolved.[3]


A prevailing theory about Jack the Ripper pointed at a suspect named Aaron Kosminski.

In 2013 after Clifford DeVoe gained meta-human power of accelerated thinking, his wife, Marlize DeVoe, asked him who Jack the Ripper was. After pointing at Kosminski, DeVoe shared his own masterfully-crafted theory that the Ripper was Catharine Jewell, Kosminski's nurse at Colney Hatch Asylum.[3]

In 2018 when Nora West-Allen debriefed Team Flash on Cicada's modus operandi, Cisco Ramon described him as a "meta-human Jack The Ripper".[4]
