Johannes von Mikulicz-Radecki

Born 16 May 1850; died 4 Jun 1905 at age 55.Polish surgeon whose innovations in operative technique for a wide variety of diseases helped develop modern surgery. He contributed prodigiously to cancer surgery, especially on organs of the digestive system. He was first to suture a perforated gastric ulcer (1885), surgically restore part of the oesophagus (1886), remove a malignant part of the colon (1903), and describe what is now known as Mikulicz' disease. In 1881 he developed improved models of the oesophagoscope and gastroscope. As an ardent advocate of antiseptics he did much to popularize Joseph Lister's antiseptic methods. He used a gauze mask and was one of the first to use gloves during surgery.
