Jan F. Esser

Johannes Fredericus Samuel Esser was a Dutch plastic surgeon who pioneered innovative methods of reconstructive surgery on soldiers wounded in the First World War. He is thought to have coined the term "stent" in 1917 to describe his use of a dental impression compound invented in 1856 by the English dentist Charles Stent to create a form for facial reconstruction. The term "stent" was later extended to mean a device to expand constricted tubes of body tissue.
He was a one time Dutch Chess Champion, winning the Dutch Championship in a play-off match for the title against Rudolf Loman in 1913. He also won an unofficial Dutch Chess Championship in 1908
