Bertillon, brother of Alphonse Bertillon, was Chief of Statistical Services for the city of Paris. His classification of diseases was based on the principle, adopted by Farr, of distinguishing between general diseases and those localized to a particular organ or anatomical site. This became the basis for the International Classification of the Causes of Sickness and Death. Digital facsimile from the Internet Archive at this link.
