Hedge fund veteran David Gelbaum--famed for his role in helping build Princeton-Newport Partners into the first market neutral hedge fund, and more recently for his clean technology investments--recently made headlines for withdrawing his annual $20 million gift to the American Civil Liberties Union for 2010. Gelbaum's gift withdrawal, which represents 25% of the ACLU's annual budget and is said to be due to market conditions, has sparked speculation that the billionaire investors' finances could be in trouble.
