A modern-day devotee of Epictetus was Admiral James Stockdale, best known for being Ross Perot's 1992 running mate. He wrote two great essays on how stoicism influenced his life, especially during his time as the senior naval prisoner of war in North Vietnam.
In fairness to his audience, it wouldn't have been a big deal if he were otherwise polished and practiced at public speaking, debates, interviews, etc. As it was he looked like a goof most of the time, so most people actually were thinking "Ok, Seriously: who is this guy and why is he here?"
