Snow was a London medic, who worked closely with William Farr. Their work in identifying the source of the 1854 cholera outbreak in Broad St to an infected water supply was a landmark in epidemiology.
Snow lodged in 1836 at 11 Bateman Buildings, Soho Square (this is a road parallel to and between Frith St and Greek St) and from 1858 at 54 Frith St, Soho. He died at 18 Sackville St, Piccadilly and is buried in Brompton cemetery.
