Supporting early childhood, neuroscience, and education.

About

For four decades, the Fund has supported early career scientists engaged in basic or clinical neuroscience research. The Fund has also been engaged in the training of independent school teachers and leaders largely through the work of the Klingenstein Center at Teachers College, Columbia University. In recent years, the Fund has added a program in early childhood that focuses on making systemic changes in child care and early childhood mental health.

Our Mission

The EAJK Fund is committed to promoting breakthrough neuroscience research, improving early childhood care and education (particularly among low income children), and enhancing the development of teachers and leaders in independent schools.

History of the Esther A. and Joseph Klingenstein Fund

The EAJK Fund was established in 1945 by Esther and Joseph Klingenstein. Joe Klingenstein was a co-founder of the investment firm Wertheim and Company.

During their lifetimes, Esther and Joe’s concern for individual human welfare was reflected in contributions they made primarily to institutions in which they were personally involved, mainly in the New York City area. Most of these were Jewish causes, such as the Jewish Home for the Aged, where Esther was very active, and hospitals, especially Mount Sinai, where Joe often volunteered after his workday had ended. Joe led Mount Sinai as its Board Chairman for many years and along with his brother-in-law Milton Steinbach, was instrumental in helping establish its medical school.

When John Klingenstein, Esther and Joe’s son, took the reins of the family’s philanthropy in the early 1970s, he applied his considerable business experience and engineering training toward bringing a more business-like and disciplined approach to philanthropy. To promote neuroscience research, John and his brother Fred established the Klingenstein Fellowship Awards in Neuroscience in 1981. Now called the Klingenstein-Simons Fellowship Awards in Neuroscience, it has helped advance the work of many of the country’s finest neuroscientists.

John also led the effort to establish the Klingenstein Center at Teachers College, Columbia University in 1977, which offers leadership programs and degrees for independent schoolteachers and administrators. After John passed away in August 2018, his bequest to Teachers College permanently endowed the Klingenstein Center.

Since 2013, Andy Klingenstein has served as Chairman and CEO of the EAJK Fund. A lawyer by training, he has managed several of our foundations, and has advised both for-profit companies and nonprofit organizations for many years. Other trustees include his three siblings (Tom, Nancy, and Sally), his wife Julie and – since 2018 – their daughter Emma Brownstein and cousin Al Klingenstein. Patricia Klingenstein served on the board of the Fund from 2013 until she passed away in 2023.
