While visiting London today, I stopped by the location of the pump from Snow&#x27;s Cholera map:<p><a href="https:&#x2F;&#x2F;www.google.co.uk&#x2F;maps&#x2F;@51.5133626,-0.1366315,3a,75y,189.49h,75.97t&#x2F;data=!3m6!1e1!3m4!1sYuG6zRfL8xHbyVSwH3Q_8g!2e0!7i13312!8i6656!6m1!1e1" rel="nofollow">https:&#x2F;&#x2F;www.google.co.uk&#x2F;maps&#x2F;@51.5133626,-0.1366315,3a,75y,...</a><p>There&#x27;s a pub there named after John Snow, but the area seems otherwise unremarkable.<p>His contributions are discussed in the first episode of How We Got to Now, which is a pretty good documentary available on Netflix:<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;How_We_Got_to_Now" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;How_We_Got_to_Now</a>
