Andy Lowenfeld, a member of the Board of Editors of this journal from 1978 to 1995, and an honorary editor thereafter, died on June 9, 2014, a few days after his eighty-fourth birthday, in New York City.Everyone who knew him, as friend, or colleague, or student, or client, wondered at his sparkling intellect, infectious humor, imagination, and boundless curiosity. He always questioned. He never took anything for granted. He was no narrow specialist. His interests included aviation law, international economic law, private international law, public international law, and procedural law. More than any other author or practitioner in the United States, he decried “the unconvincing separation between public and private international law” and practiced what he preached.
