Biography[]
Aron Mordke Kosminski was born in Klodawa in the Russian Empire (present-day Poland) on 11 September 1865 to a Jewish family, and he emigrated to the United Kingdom in 1881 to escape anti-Jewish pogroms in the Russian dominions. Although he gained a job, his schizophrenia set him onto a murderous rampage. He slit the throats of 7 prostitutes, raped one, strangled one, stabbed one to death after 39 jabs, and dismembered one in what became known as the 1888-1891 "Whitechapel Murders". Kosminski dressed in dark clothing and became known to the public only as "Jack the Ripper"; nobody knew who he was until semen stains on the corpse of Catherine Eddowes were analyzed in 2014, revealing his DNA. "Jack the Ripper" was initially thought to be British royalty. A theory goes that after the end of the murders happened in 1891 in Britain, he moved to the United States, as similar murders began shortly after the end of the ones in Britain. However, the killings stopped because Kosminski was checked into an insane asylum. The doctors did not know of his identity, so he evaded the noose and he died of gangrene in 1919.
