Philippus Aureolus Theophrastus Bombastus von Hohenheim, Paracelsus

Many books mentioning Paracelsus also cite him as the origin of the word "bombastic"* to describe his often arrogant speaking style, which the following passage illustrates:

I am Theophrastus, and greater than those to whom you liken me; I am Theophrastus, and in addition I am monarcha medicorum and I can prove to you what you cannot prove...I need not don a coat of mail or a buckler against you, for you are not learned or experienced enough to refute even a word of mine...As for you, you can defend your kingdom with belly-crawling and flattery. How long do you think this will last?...Let me tell you this: every little hair on my neck knows more than you and all your scribes, and my shoe buckles are more learned than your Galen and Avicenna, and my beard has more experience than all your high colleges.

— Paracelsus, Selected Writings

*Boring accuracy:  According to the Oxford English Dictionary, the origin of the word "bombastic" is "bombast", an old term for cotton stuffing, rather than a play on Paracelsus's middle name, Bombastus.~~Wikipedia
