Ambroise Pare was a 16th century French surgeon who made several important contributions to the field of surgery. Through his experience as a military surgeon, he discovered that treating gunshot wounds with a new "digestive" ointment method healed patients better than the standard practice of cauterizing the wounds with boiling oil. He published his findings in a landmark book in 1545. Pare is also known for introducing ligatures to control bleeding during surgery and new techniques like suturing wounds. He served as a surgeon to four French kings and helped establish surgery as a respected medical profession.
