Pump placed as a memorial to the pioneering physician John Snow. In 1854 Snow, an early proponent of the germ theory of disease, localised an outbreak of Cholera to a pump near this spot. He had the handle removed, helping to quell the outbreak.

This isn't the original pump, and it isn't quite on the site of the original pump, but it commemorates probably the most famous pump in London.
In 1854 it was generally believed that cholera was transmitted by "bad air" or "miasma". The physician John Snow argued to the contrary, that it was water borne. In 1854, in what was the first comprehensive epidemiological study, he studied an the location of cases of a cholera outbreak in London and deduced that the source was a water pump on Broad Street (as it was then known). Snow prevailed upon the authorities to remove the pump handle, and the outbreak subsided.
The location of the original pump is marked by a slab of pink granite in the pavement outside the nearby John Snow pub.
