Legacy Society

COSI’s Legacy Society recognizes and honors individuals who have advised us of their plans to give a future gift to COSI through a will, estate plan or endowed gift. Legacy Society donors are partners in COSI’s mission, making it possible for us to offer innovative, hands-on learning experiences for those of all ages for generations to come.

We encourage COSI supporters and friends to designate a gift in their estate plan and become a member of COSI's Legacy Society. In many cases, legacy gifts have significant tax and financial rewards for donors. With your support, we can continue to inspire interest in science and encourage people to want to learn more about their world.
