Lassa Francis Lawrence Oppenheim (30 March 1858 – 7 October 1919) was a German jurist. He has been characterized as the father of the modern discipline of international law, especially the hard legal positivist school of thought. His two-volume International Law: A Treatise has influenced international law. He inspired Joseph Raz and Prosper Weil.
