Here's something I worked on a while back at Culture Trip for a article about The Broad Street pump, The pump sits outside the John Snow pub in Soho. The pub is named after the scientist John Snow, who discovered that cholera was transmitted by unsanitary water. The pump still stands outside the pub as a reminder to locals of the discovery. https://theculturetrip.com/europe/united-kingdom/england/london/articles/soho-icons-the-broad-street-pump/
