Mental and Moral Heredity in Royalty. A Statistical Study in History and Psychology - Frederick Adams Woods

Frederick Adams Woods examined the biographical records and family trees of the great dynasties of Europe, judging and comparing their moral standards and intellectual aptitude to their reputation as rulers. The summarised family histories are produced after a painstaking search including portrait galleries, family lineage, comparisons of reputation, and the origin of allegations of madness and moral bankruptcy, all collated within a single volume. - Summary by Leon Harvey
