Who is the one person's name achieved cheating death...?

Question

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.

PALPATINE: Good.

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?

Answer 1

Darth Plagueis The Wise

There is a scene earlier in the movie about this:

Palpatine: Did you ever hear the tragedy of Darth Plagueis The Wise?

Anakin: No?

Palpatine: I thought not. It’s not a story the Jedi would tell you. It’s a Sith legend. Darth Plagueis was a Dark Lord of the Sith, so powerful and so wise he could use the Force to influence the midichlorians to create life… He had such a knowledge of the dark side, he could even keep the ones he cared about from dying.
