The entry on Henry Sidgwick by Barton Schultz has been revised.  Many legal academics are not aware of Sidgwick's significance.  As Schultz writes:

Henry Sidgwick was one of the most influential ethical philosophers of the Victorian era, and his work continues to exert a powerful influence on Anglo-American ethical and political theory. His masterpiece, The Methods of Ethics (1907), was first published in 1874 and in many ways marked the culmination of the classical utilitarian tradition—the tradition of Jeremy Bentham and James and John Stuart Mill—with its emphasis on “the greatest happiness of the greatest number” as the fundamental normative demand. Sidgwick's treatment of that position was more comprehensive and scholarly than any previous one, and he set the agenda for most of the twentieth-century debates between utilitarians and their critics.
