So this was the state of London in 1854, and in the middle of all this carnage and offensive conditions, and in the midst of all this scientific confusion about what was actually killing people, it was a very talented classic 19th century multi-disciplinarian named John Snow, who was a local doctor in Soho in London, who had been arguing for about four or five years that cholera was, in fact, a waterborne disease, and had basically convinced nobody of this.
Era este o estado de Londres em 1854. No meio de toda esta carnificina e condições deploráveis, no meio de toda esta ignorância científica sobre o que estava a matar as pessoas, surgiu um homem muito talentoso e multidisciplinar do século XIX, chamado John Snow, um médico local do Soho, em Londres, que defendia há já quatro ou cinco anos que a cólera era uma doença transmissível pela água, mas que não tinha convencido ninguém.
