Norman S. Poser (Brooklyn Law School). Lord Mansfield: Justice in the Age of Reason (McGill-Queen's University Press, 2013).
"Mr. Poser offers us a fascinating portrait.
Awarded an earldom by George III, Mansfield was a typical 18th-century
grandee, ruthlessly ambitious and casually venal. His career made him
extremely rich, and his guarded political style often appeared
unscrupulously calculated to accelerate his own advancement. But his
mind was extraordinary, and he worked with legendary intensity. . . . Mansfield's judgments
ingrained themselves into the legal culture of the English-speaking
world. Modern rules governing the use of expert testimony, for instance,
trace to Mansfield. The U.S. Supreme Court, Mr. Poser informs
us, has cited Mansfield more than 300 times, on issues from defamation
to parental rights."
