Cause of death: natural cause
Ambroise Paré (French pronunciation: [ɑ̃bʁwaz paʁe]; c. 1510 – 20 December 1590) was a French barber surgeon who served in that role for kings Henry II, Francis II, Charles IX and Henry III. He is considered one of the fathers of surgery and modern forensic pathology and a pioneer in surgical techniques and battlefield medicine, especially in the treatment of wounds. He was also an anatomist, invented several surgical instruments, and was a member of the Parisian barber surgeon guild.
In his personal notes about the care he delivered to Captain Rat, in the Piémont campaign (1537–1538), Paré wrote: Je le pansai, Dieu le guérit ("I bandaged him and God healed him"). This epitomises a philosophy that he used throughout his career. These words, inscribed on his statue in Laval, are reminiscent of the Latin adage medicus curat, natura sanat, "The physician cures, nature heals".
