Lassa Francis Lawrence Oppenheim (1858-1919), was a renowned German jurist. He is regarded by many as the father of the discipline of international law. Born in Windecken near Frankfurt, Germany and educated at the Universities of Berlin, Göttingen, Heidelberg and Leipzig, he went to England in 1895 and lived there until his death. He first lectured at the London School of Economics and in 1908 became the Whewell Professor of International Law in the University of Cambridge. He is the author of the internationally renowned International Law: A Treatise, the first edition of which was published in 1905-1906. The eighth edition of the part on peace was edited by Sir Hersch Lauterpacht; the ninth and most recent edition of the same part was co-edited by Sir Robert Jennings and Sir Arthur Watts. The work is still considered as the standard text of International Law. His other works include The Panama Canal Conflict Between Great Britain and The United States of America (1913).
