Supporting early childhood, neuroscience, and education.

About

For four decades, the Esther A. & Joseph Klingenstein Fund has supported early career scientists engaged in basic or clinical neuroscience research. In recent years, the Fund has added a program in early childhood that focuses on improving the mental health and well-being of young children, and a program in early literacy that focuses on building the national science of reading movement and improving reading for children in grades kindergarten through three.

Our Mission

We are committed to investing in breakthrough neuroscience research, improving early childhood mental health and well-being, and ensuring that all children can read.

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, a member of the third generation, has served as Chairman and CEO of the EAJK Fund. Current trustees include Andy’s siblings Nancy and Sally, his wife Julie and – since 2018 – their daughter Emma Brownstein and cousin Al Klingenstein. In 2023, the EAJK board welcomed family members Alexandra Klingenstein, Greg Brownstein, and Zack Toal.  Patricia Klingenstein served on the board of the Fund from 2013 until she passed away in 2023.
