Dr John Snow is famous for several reasons, but one is his analysis of the incidence of outbreaks of cholera in London in 1954. He caused the removal of the handle of one particular pump in Soho, London that was dispensing contaminated water. There is much more about him on the internet e.g. wikipedia.
My client, an ex-medic, wanted a special gift that reflected his experience in epidemiology.
He said “John Snow pump received, looks just lovely, will be giving it to my wife later today. So very many thanks. A really wonderful and personal souvenir “
