great measure of control despite the fact that the Constitution grants the legislative branch the power to declare war. As the practice of foreign affairs had become more complex, he detailed how Congress had gradually acceded to the President greater control in conducting American foreign relations and showed that it had not taken adequate precautions in the way these powers were wielded by the executive. In his 1990 work Constitutionalism, Democracy and Foreign Affairs Henkin reiterated his concerns about the growth of the Imperial Presidency and its effect on the way the nation's foreign affairs were conducted, emphasizing that the preservation of human rights must play an important role. This and other books such as The Rights of Man Today, How Nations Behave, and Age of Rights, comprised a collection of works that The New York Times described in his obituary as being "required reading for government officials and diplomats". He was the Chief Reporter of the influential Restatement (Third) of the Foreign Relations Law of the United States. Henkin died at age 92 on October 14, 2010, at his home in Manhattan after a long illness with Alzheimer’s disease. He was survived by his wife, Alice Hartman Henkin, as well as by three sons—his eldest, Joshua Henkin, is a novelist. His second son, David Henkin, is a professor of American history at the University of California, Berkeley. His youngest son, Daniel Henkin, is the Director of Music at the Ramaz School—and five grandchildren.
