Stensen of Stensen’s Duct
Niels Stensen (1638 –1686), a.k.a. Nicolaus Steno, was born in Copenhagen, Denmark, where as a youngster he became proficient in a variety of languages, including German, French, Italian, English, Greek, Latin, and Hebrew. After 2 years at the university in Copenhagen, where his preceptor was Thomas Bartholin, Stensen transferred to Amsterdam. It was as a student there that, while dissecting a sheep’s head, he identified the main duct of the parotid gland that now bears his name. His discovery was disparaged by his superior Gerhard Blasius who insisted the function of the parotid gland was not secretory, but rather its purpose was to warm the ear. Stensen’s view prevailed when he went on to demonstrate further evidence of glandular secretion. By way of Paris, he traveled to Florence where he was appointed court physician to Ferdinand II, a patron of the sciences. There he converted to Catholicism, wrote theological treatises, and became a bishop. —Contributed by WILLIAM S.
