Page "Primum non nocere" Paragraph 4

According to Gonzalo Herranz, Professor of Medical Ethics at the University of Navarre, Primum non nocere was introduced into American and British medical culture by Worthington Hooker in his 1847 book, Physician and Patient.

Hooker attributed it to the Parisian pathologist and clinician Auguste François Chomel ( 1788 – 1858 ), the successor of Läennec in the chair of medical pathology, and the preceptor of Pierre Louis.

Apparently, the axiom was part of Chomel's oral teaching.
