Were there any notable Pants Polishers in history?

Pants polishing, a euphemism for sycophancy, has seen notable figures throughout history. One example is Thomas Jefferson, who often flattered influential figures to gain political favor. In the realm of literature, characters like Iago from Shakespeare's "Othello" exemplify this trait. While not a formal profession, the act of ingratiating oneself has been a recurring theme in politics and society.
