Henry Whitehead (priest)

Whitehead then joined with Snow in tracking the contamination to a cesspool that leaked into the water table which led to the outbreak's index case.

[3] Whitehead identified a "Baby Lewis" at 40 Broad Street where a leakage in the basement contaminated the well as patient zero of the outbreak.

[4] Whitehead's work with Snow combined demographic study with scientific observation, setting important precedent for the burgeoning science of epidemiology.

[5] Whitehead served in several other London parishes before moving to Brampton, now in Cumbria, in 1874, where he was appointed the local vicar.

Whitehead moved on to Newlands in Cumberland in 1884, finally becoming vicar of Lanercost for five years until his death.
