He also discovered the thoracic canal.

Although he died on August 27th, 1574, we still remember Bartolomeo Eustachi because he described these little tubes we have in our heads that connect our throats with our ears. “Eustachian” is not a descriptive adjective, and though gone almost 450 years Bartolomeo’s name is spoken by pediatricians every time a kid gets an earache. It makes one wonder about one’s own legacy. Today all the tubes have names so I think after I’m gone if I’m remembered at all I’d like for people to be able to say, “Wow, just like that, huh? He never knew what hit him.”
