Descartes

Who he?
An infamous Mr. Bean and Captain Hook impersonator way before his time, René Descartes (1596-1650) was a Dualist who believed that mind an body were two separate substances and did such a good job arguing this that he tripped himself up in later not being able to explain how the two function together. PINEAL GLAND! In his lifetime, he would teach a certain  Princess Elizabeth of Bohemia  who would prove to be the very best kind of student in asking him things he  didn't know how to answer  in their correspondence via snail mail.
