there's a good book on the 'rest' of livermore's life, released last year, by richard smitten.
womanizer? definitely. gambler? wouldn't doubt it (though it's not mentioned). the trust thing, apparently, was her doing - after the divorce, she switched it out of what he put it in and put it elsewhere.
livermore is probably the trader i've learned the most from - both things to do, and what NOT to do...not only in trading, but in elements of life.
