Kenneth Waltz

About the Author

Kenneth Waltz (1924-2013) was a pioneering American political scientist and international relations theorist whose work profoundly shaped the field of global politics. Educated at Columbia University, he earned his PhD in 1954 and went on to teach at institutions including Swarthmore College, the University of California, Berkeley, and Columbia. Waltz is best known for developing neorealism, a structural theory emphasizing the anarchic nature of the international system and the enduring role of power balances among states. His seminal book, Man, the State, and War: A Theoretical Analysis, published in 1959, dissects the causes of war through levels of analysis from human nature to international structure, offering timeless insights into conflict and stability. Waltz's rigorous, parsimonious approach continues to influence scholars, policymakers, and debates on security and world order.
