A private library is seen inside the Highland Park residence of Harlan Crow, chairman and chief executive officer of Crow Holdings LLC, not pictured, in Dallas, Texas, U.S., on Friday, Oct. 2, 2015. What was once a psychiatric hospital, Old Parkland became the pet project of Crow; on its campus are seven Jeffersonian-style buildings that house a hive of private-equity firms, hedge funds, foundations and family offices.
