Lester Levenson, a bit of a hero of mine. In the 1950′s he was sent home to die after his third heart attack.
He was told he only had weeks to live. Being a physicist he wondered what it was that was causing the malfunction in his heart and came up with the idea that it was trapped emotional energy.
He cured himself easily three weeks later and also released the control of the ego within him, so he had a life of freedom thereafter. He called it the Release Technique.
He died in 1994 aged 84.
Here is a great audio of him speaking.
