We are deeply saddened to announce the passing of John Klingenstein, one of our founding members and a Principal of Klingenstein Fields Advisors (KF Advisors). In 1989, John, his brother, Frederick A. Klingenstein, and colleague, Kenneth H. Fields, established Klingenstein Fields & Company, L.L.C., now known as KF Advisors.
As many of you know, John was also deeply committed to the community and giving back, particularly in the field of education. He served as President of The Esther A. & Joseph Klingenstein Fund for over forty years and was President Emeritus of the Fund at the time of his death. John was also a trustee of Teachers College, Columbia University, Trustee Emeritus of The Rensselaerville Institute and on the Executive Committee of the Rockefeller University Council.
At this sad time, our thoughts and sympathy are with John’s wife Pat, his children, Tom, Nancy, Andy and Sally, ten grandchildren, and one great-grandchild. KF Advisors will continue to strive at all times to live up to his enduring personal and business legacy.
