A new book about the late U.S. Supreme Court Justice Tom Clark and his son, Ramsey, the former U.S. attorney general, sheds new light on an extraordinary pair of lawyers who had a long-term impact on the law in the 20th century.

Father, Son and Constitution, published by the University of Kansas Press, is by Alexander Wohl, a former Supreme Court judicial fellow now an adjunct professor at American University Washington College of Law.
