Nicolas Steno (1638-1686), Danish anatomist, geologist, and bishop. Steno (born Niels Stensen) discovered muscle fibers, Steno's duct in the parotid salivary gland, and the pineal gland in animals, challenging the view that this gland contained the human soul. As a geologist, Steno formulated Steno's Law, drew the earliest rock strata, and postulated that fossils were the remains of ancient animals. Stock Photo
