This was a short series, but we still want to set the record straight: correct our mistakes, elaborate on stories we left out, and reflect on what we've learned! One of the recurring themes of the Broad Street Pump series was people's continued resistance to John Snow's theories, even when he collected evidence to back them. But in the end, the truth won out: the march of progress can be very slow, since individual people cling to what they know and what feels most comfortable to them, but in the course of time, we do come to accept the truth. What seemed so unbelievable back then is common knowledge now. John Snow's struggles may have seemed futile at the time, and he watched himself dismissed at every turn, but his efforts added up to the foundation of epidemiology and contributed to the acceptance of germ theory.
