Princeton University (NJ) President Christopher L. Eisgruber writes:  When he retires next year after running the Princeton University endowment for nearly 30 years, Andrew Golden will be acknowledged as one of the most successful university investment managers of all time. Andy’s key statistic is 12.6 percent. That’s the annualized return earned by Princeton’s endowment during his tenure, well above the 8.5 percent industry benchmark. The Golden touch has dramatically boosted Princeton’s ability to invest in financial aid, scientific research, and sustainability programs for the benefit of the country and humanity.
