Sigrid Leube Snell died peacefully on June 24, 2025 at her Haworth, New Jersey home, where she had lived since 1954. Born in Stuttgart, Germany on January 1, 1927, she was the fourth child of Clara Kuntze and Maximilian Leube, who was physician in charge at a prominent Stuttgart hospital. In 1948, after attending Heidelberg University for two years, Sigrid was among the very first German students to receive a scholarship to study in the U.S. post-World War II. She received an A.B. degree (magna cum laude, Phi Beta Kappa) from Stanford University in 1950, after which she pursued graduate study in Spanish at Middlebury College and then earned an M.A. and completed much of the work toward a doctorate in international relations from New York University.
