Alexander and his wife Lucy founded the A. D. Henderson Foundation in 1959 with the mission to improve the education and support systems for children, ensuring that all children have the opportunity to reach their full potential.
The grant program by the A.D. Henderson Foundation emphasizes strengthening early childhood programs and supporting programs that enable families with young children to thrive in Broward County, Florida, and the State of Vermont. The program has three main goals: 1) Strengthen early childhood programs by supporting early childhood development programming and improving the capacity of early care and education programs, 2) Support programs that enable families with young children to thrive through funding for direct services and improving the capacity of programs for families with young children, and 3) Engage in systems change to enhance early childhood programs and families' ability to thrive through advocacy and opportunities for systems change addressing the needs of families with young children.
