A physicist with three Harvard degrees but no medical license said he is ready to begin the first step toward immortality: He will clone himself.

Richard Seed, who provoked controversy earlier this year by announcing plans to clone humans, said that the first person he will try to copy will be himself, The Boston Globe reported Sunday.Seed said his wife, Gloria, has agreed to carry an embryo that would be created by combining the nucleus of one of his cells with a donor egg, the newspaper said.

"I have decided to clone myself first to defuse the criticism that I'm taking advantage of desperate women with a procedure that's not proven," the 69-year-old physicist said Saturday at a meeting of the Association for Politics and the Life Sciences, a group of academic researchers.
