Hans Morgenthau
German-American jurist and political scientist; leading post-WWII realist.
Hans Joachim Morgenthau, born on February 17, 1904, and died on July 19, 1980, was a German-American jurist and political scientist who emerged as a key figure in 20th-century international relations. His thinking falls within the realist tradition of international relations theory, and he is widely regarded as one of the most significant realists of the post-World War II era. Morgenthau contributed substantially to both international relations theory and international law. His 1948 book *Politics Among Nations*, which went through five editions in his lifetime, became a standard textbook in American universities. Although Morgenthau stressed the importance of power and "the national interest," the book’s subtitle—"the struggle for power and peace"—shows he also cared about how ethical and legal norms could constrain that struggle.
Beyond his books, Morgenthau wrote frequently on international politics and U.S. foreign policy for general-interest outlets such as *The New Leader*, *Commentary*, *Worldview*, *The New York Review of Books*, and *The New Republic*. He corresponded with and knew many leading intellectuals of his time, including Reinhold Niebuhr, George F. Kennan, Carl Schmitt, and Hannah Arendt. During the early Cold War, he served as a consultant to the U.S. Department of State while Kennan led its Policy Planning Staff, and later advised the Kennedy and Johnson administrations until Johnson dismissed him for publicly criticizing American policy in Vietnam. For most of his career, though, he was respected as an academic interpreter of U.S. foreign policy.
Morgenthau was born into an Ashkenazi Jewish family in Coburg, Saxe-Coburg and Gotha, Germany, in 1904. He attended the Casimirianum, then studied at the Friedrich Wilhelm University of Berlin, the University of Frankfurt am Main, and the Ludwig-Maximilians-Universität München. He earned his doctorate in 1929 with a dissertation titled *International Jurisdiction: Its Nature and Limits*, and completed postdoctoral work at the Geneva Graduate Institute in Switzerland. Before emigrating to the United States in 1937, he taught and practiced law in Frankfurt, with interim years in Switzerland and Spain. His first American job was teaching night school at Brooklyn College. From 1939 to 1943, he taught in Kansas City and at Keneseth Israel Shalom Congregation there. He then became a professor at the University of Chicago until 1973, after which he took a professorial chair at the City College of New York. In the early 1950s, he was a visiting professor at Harvard, where he taught a graduate seminar and met Henry Kissinger, then working on his dissertation. Morgenthau was elected to the American Academy of Arts and Sciences and the American Philosophical Society.
After moving to New York, he separated from his wife, who stayed in Chicago partly due to medical issues. He reportedly tried to start a new relationship with Ethel Person (d. 2012), a psychiatrist at Columbia University. On October 8, 1979, Morgenthau was a passenger on Swissair Flight 316, which crashed while attempting to land at Athens-Ellinikon International Airport; the flight was headed for Bombay and Peking. He died on July 19, 1980, shortly after being admitted to Lenox Hill Hospital in New York with a perforated ulcer. He is buried in the Chabad section of Montefiore Cemetery, near the Lubavitcher Rebbe, with whom he had a respectful relationship.
Morgenthau completed his doctoral dissertation in Germany in the late 1920s, published in 1929 as his first book, *The International Administration of Justice, Its Essence and Its Limits*. Carl Schmitt, then a jurist at the University of Berlin, reviewed it. In an autobiographical essay written near the end of his life, Morgenthau recalled that he had looked forward to meeting Schmitt during a visit to Berlin, but the meeting went poorly, and he left feeling he had encountered what he called "the demonic." By the late 1920s, Schmitt was becoming the leading jurist of the rising Nazi movement, and Morgenthau saw their positions as irreconcilable. (The editors of Morgenthau’s *The Concept of the Political* note that readers will easily recognize that Morgenthau rejected Schmitt’s understanding of the political on both moral and conceptual grounds.)
After his doctorate, Morgenthau left Germany to complete his Habilitation dissertation in Geneva. It was published in French as *La Réalité des normes en particulier des normes du droit international: Fondements d'une théorie des normes* and has not been translated into English. The legal scholar Hans Kelsen, who had just arrived in Geneva as a professor, advised Morgenthau on this dissertation. Kelsen was among the strongest critics of Carl Schmitt, and he and Morgenthau became lifelong colleagues, even after both emigrated to the United States. In 1933, Morgenthau published a second book in French, *La notion du "politique"*, translated into English in 2012 as *The Concept of the Political*. In it, he tries to distinguish legal disputes between nations from political disputes between nations or other litigants. The questions driving this inquiry are...

Lore & Background
Morgenthau was born into an Ashkenazi Jewish family in Coburg, Saxe-Coburg and Gotha, Germany in 1904. After attending the Casimirianum, he studied at the Friedrich Wilhelm University of Berlin, the University of Frankfurt am Main, and the Ludwig-Maximilians-Universität München. He received his doctorate in 1929 with a thesis entitled *International Jurisdiction: Its Nature and Limits*, and pursued postdoctoral work at the Geneva Graduate Institute, in Switzerland. He taught and practiced law in Frankfurt before emigrating to the United States in 1937, after several interim years in Switzerland and Spain. One of his first U.S. jobs was teaching night school at Brooklyn College. From 1939 to 1943, Morgenthau taught in Kansas City and taught at Keneseth Israel Shalom Congregation there. He then was a professor at the University of Chicago until 1973, when he took a professorial chair at the City College of New York. In the early 1950s, Morgenthau was a visiting professor at Harvard, teaching a graduate seminar; at that time he met Henry Kissinger, who was working on his dissertation. He was an elected member of the American Academy of Arts and Sciences and the American Philosophical Society. In his European years, Morgenthau completed his doctoral dissertation, published in 1929 as his first book, *The International Administration of Justice, Its Essence and Its Limits*. It was reviewed by Carl Schmitt, then a jurist teaching at the University of Berlin. Morgenthau later related that meeting Schmitt went badly and he left thinking he had been in the presence of "the demonic." His Habilitation dissertation, published in French as *La Réalité des normes en particulier des normes du droit international: Fondements d'une théorie des normes*, was advised by Hans Kelsen, who became a lifelong colleague. In 1933, Morgenthau published a second book in French, *La notion du "politique"*, translated into English in 2012 as *The Concept of the Political*. In these early works, Morgenthau sought a "functional jurisprudence," an alternative to mainstream international law, borrowing ideas from Sigmund Freud, Max Weber, Roscoe Pound, and others. In 1940 he set out a research program for legal functionalism in the article "Positivism, Functionalism, and International Law."
During the American years, Morgenthau became a founding father of the realist school. His *Scientific Man versus Power Politics* (1946) argued against an overreliance on science and technology as solutions to political and social problems, presenting a "pessimistic view of human nature" centered on a universal lust for power. *Politics Among Nations* (1948) went through five editions during his lifetime and was widely adopted as a textbook in U.S. universities. Starting with the second edition, Morgenthau included a section called "Six Principles of Political Realism." He wrote widely about international politics and U.S. foreign policy for publications such as *The New Leader*, *Commentary*, *Worldview*, *The New York Review of Books* and *The New Republic*. He knew and corresponded with Reinhold Niebuhr, George F. Kennan, Carl Schmitt and Hannah Arendt. At one point in the early Cold War, Morgenthau was a consultant to the U.S. Department of State when Kennan headed its Policy Planning Staff, and a second time during the Kennedy and Johnson administrations until he was dismissed by Johnson when he began to publicly criticize American policy in Vietnam. On October 8, 1979, he was one of the passengers on board Swissair Flight 316, which crashed while trying to land at Athens-Ellinikon International Airport. He died on July 19, 1980, shortly after being admitted to Lenox Hill Hospital in New York with a perforated ulcer. He is buried in the Chabad section of Montefiore Cemetery, in proximity to the Lubavitcher Rebbe, with whom he had a respectful relationship.
Reader's Guide
Hans Morgenthau's significance lies in his foundational role in shaping 20th-century international relations theory through the realist tradition. His *Politics Among Nations* became a widely adopted textbook in U.S. universities, defining the field's focus on power and national interest. However, his realism was more nuanced than often portrayed: the subtitle "the struggle for power and peace" reflects his concern with ethical and legal norms as limits on power. Recent scholarly assessments show his intellectual trajectory was more complicated than originally thought, with moral considerations infused into his realism—though not always acknowledged as such. Morgenthau's early work in functional jurisprudence sought to bridge international law and politics, though Francis Boyle has written that his post-war writings may have contributed to a "break between international political science and international legal studies." His later opposition to the Vietnam War and advocacy for supranational control of nuclear weapons demonstrate the evolution of his thought. Morgenthau is sometimes referred to as a classical realist or modern realist to differentiate his approach from the structural realism or neo-realism associated with Kenneth Waltz. His legacy endures as a central figure in classical realism, and his writings continue to be studied for their insights into power, ethics, and international order.
