Endowment and Restricted Gifts

Restricted and endowment funds from generous donors are vital to ensuring that the Society will continue to fulfill its mission of “promoting useful knowledge.”  Through a restricted or endowment gift, you can support areas of the Society that align with your interests.  The Society’s endowment has grown steadily over time thanks to generous gifts, sound investments, and careful use of yearly returns.
