Hans von Gersdorff (1455-1529) was a German surgeon and medical writer who lived during the 15th and early 16th centuries. He is best known for his military surgical experience and his influential medical manual, the Feldtbuch der Wundarzney (Field Book of Wound Medicine), which became one of the most widely used surgical textbooks in medieval Europe. His work played a crucial role in shaping the field of surgery, particularly in the treatment of battlefield injuries, amputations, and wound care.
