In the Star Wars movie Revenge of the Sith we can see he below dialog between Anakin and Sidious (PALPATINE) after Anakin killed all Jedis:
ANAKIN: What have I done?
PALPATINE: You are fulfilling your destiny, Anakin. Become my apprentice. Learn to use the dark side of the Force.
ANAKIN: I will do whatever you ask.
ANAKIN: Just help me save Padme's life. I can't live without her. I won't let her die. I want the power to stop death.
PALPATINE: To cheat death is a power only one has achieved, but if we work together, I know we can discover the secret.
So my question is, is PALPATINE saying the one person's name who achieved cheating death?
