I think you'll find Margaret Coit's biography of Baruch to be the best and most exhaustive survey and analysis of his life and gifts. It doesn't include speculation as to his personal peccadilloes. None of us are perfect.
Baruch accumulated capital prodigiously in the early portion of his life, but systematically disbursed it until the end of his days. And he was unstinting in his donation of himself, his mind, and his character to the country that he loved. Presidents from Woodrow Wilson to Lyndon Johnson benefited from his wise counsel.
It's my intent and hope to emulate him in all of his aspects (except the philandering).
