Scorpions: The Battles and Triumphs of FDR's Great Supreme Court Justices (2010) focuses on four of Roosevelt's Supreme Court appointees: Felix Frankfurter, Hugo Black, Robert Jackson, and William O. Douglas, and "how the backgrounds, personalities, and experiences of the four justices shaped their philosophies and how those philosophies changed the Court from a conservative one resisting America's liberal turn under FDR into the liberal one that helped remake the nation." This group biography demonstrates that their competing judicial philosophies "are the ones that continue to preoccupy lawyers, law professors and judges".
