Ex-A.I.G. Chief Is Back, Luring Talent From Rescued Firm

Maurice R. Greenberg, who built the American International Group into an insurance behemoth with an impenetrable maze of on- and offshore companies, is at it again.

Even as he has been lambasting the government for its handling of A.I.G. after its near collapse, Mr. Greenberg has been quietly building up a family of insurance companies that could compete with A.I.G. To fill the ranks of his venture, C.V. Starr & Company, he has been hiring some people he once employed.
