Clotilde Sonnino Treves, age 81, died on May 15 at her home in Princeton after a long illness. Born Clotilde Vera Rachele Sonnino, in the Trastevere quarter of Rome in 1928, she was known as 'Clo' to her many friends. She was the eldest child of a prominent Roman-Jewish family. Her father, Gabriel Sonnino, a civil court judge, was forced to flee Rome with his family in 1938. They went to Switzerland and immigrated to the USA in 1941. Clo's family settled in New York City where she attended Hunter College High School and graduated near the top of her class. In 1949, she was conferred a BA degree cum laude in political science from Pembroke College of Brown University and was elected to Phi Beta Kappa. In 1952, she married Dr. Gino Treves of Turin, Italy. The couple moved to Princeton in 1958 so that he, an organic chemist, could join the research team at the newly constructed FMC research facility on Route 1. A person of broad cultural, political and academic interests, Clo was a member of many community organizations from the 1950's through the 1980's. A devoted alumna of her college, Clo served Brown in many posts including Chairman of the New Jersey Alumni and one of 26 Regional Directors of the Brown Alumni Association. She was on the boards of the League of Women Voters, the Parent's Association of Princeton Day School, the Woman's College Club of Princeton, and on the board of McCarter Associates. Always interested in the wellbeing of foreign students, she served on the Board of AFS and as President of the Princeton Friends of Foreign Students. Clotilde Treves' intellectual interests informed her career choices. She was a language teacher and translator at the Berlitz and Inlingua Schools and a researcher in Italian history at the Institute for Advanced Study. She was a real estate agent at Stockton Real Estate for three decades. For the last 20 years, her activities became more and more focused on maintaining and operating her ancestral homestead near Rome, Italy. At the farm near Rome known as the 'Casale Sonnino', Clo continued her family's tradition of cultivating grapes and producing extra virgin olive oil. In the 1980's she opened the villa's doors to guests as an "agritourismo". Her used her vast knowledge of Italian history, art and culture in entertaining the guests and had particular success in leading tours for families and for small groups of painters. She often did the cooking for the groups entirely herself. Dozens of testimonials left by guests rave about the unique experience that Clo offered and many returned again and again to the "Casale", their "home away from home" in Italy Her passionate love of Italy and the Italians, her devotion to learning for its own sake, her sincere concern for the wellbeing of her family and for her friends made her presence quite unforgettable. She touched the heart of nearly everyone who knew her. Her moral courage, sense of responsibility, wisdom, energy and the passion with which she lived every day will be sorely missed. She is survived by two brothers, her children George, Francis and Claire and four grandchildren. A memorial service celebrating her life will be held at the Unitarian-Universalist Congregation of Princeton, 50 Cherry Hill Road, on Saturday, the 6th of June at 11:00 a.m. Contributions in Clo's honor may be made to: Brown University, PO Box 1877, Providence, RI 02912.
