Eustachio, Bartolomeo (1524–1574)
Bartolomeo Eustachio was an Italian anatomist. Aiming at first to vindicate Galen against Vesalius and others, he brought a new skill and accuracy to dissection. Eustachio was the first to describe the teeth in detail, including their basic composition of enamel and dentin. He published the first accounts of the adrenal gland and thoracic duct. The Eustachian tube of the ear is named for him. See also anatomy.
