CLINTON SMULLYAN Obituary

SMULLYAN--Clinton Ives, passed away on October 23, 2025, at the age of 75. Born in New York City on March 18, 1950, Clint was a graduate of the Buckley School, the Millbrook School and Brown University. Soon after graduating, he founded Mosbacher Properties Group which he built into a leading real estate development and investment firm with properties around the country. Clint held a lifelong and special interest in world affairs, guided by a deep belief in the power of knowledge and open societies. A generous philanthropist, he dedicated much of his life to supporting efforts that strengthened democracy and countered Russian disinformation. Through his passionate support for organizations promoting fact-based analysis, Clint made enduring contributions to the advancement of truth, democratic governance and informed foreign policy. He was a founding board member of the Jamestown Foundation and the Saratoga Foundation, both in Washington, DC. Additionally, his love of books and his wisdom about their value for humanity were hallmarks of his longtime service as a board member for the John Carter Brown Library at Brown University, the Research Libraries Board of the New York Public Library, the Council of Fellows of the Morgan Library and the Grolier Club. Among his other board involvements were service on the Chamber Music Society of Lincoln Center and PEN America. Clint was the beloved husband of Catherine Kinsey, father of Alexander and Nicholas Kinsey, father-in-law of Amanda Kinsey, grandfather of Conor, Adelaide, and Loretta Kinsey, and brother and brother-in-law of Bennett Smullyan and Rayna Upton-Haigh. He was also the godfather of Stephanie de Wangen, Julia Garrelfs, Dr. Sophie Hofferberth and Lindsay van Melle Kamp. Clint's clever sense of humor and loyalty endeared him to a legion of friends, relatives and colleagues. All who knew Clint will forever have indelible memories of him.
