Our Story
Manufacturing heir, investor and botanist Warren H. Corning began a legacy of ecological philanthropy that continues actively today. In 1949, he created the American Foundation Trust as a philanthropic vehicle to support Cleveland-area cultural organizations and to ensure his family’s continued support of the arts, education and the environment. Valuing both philanthropy and personal service, he devoted much of his personal energy and philanthropic capital to the Holden Arboretum in his hometown of Kirtland, Ohio. Not only did he give financial support, real estate, rare books and artwork to expand the fledgling center and surrounding parklands, he became its first unpaid executive administrator, and was thereafter a long-time trustee.

Corning’s ethic of philanthropic engagement passed down to his five children, including his daughter Ellen, a biologist and educator equally dedicated to local arts and culture, and his son Henry, an investor, philanthropist and environmental artist. After Ellen’s passing in 1989, her husband Dixon Long, and her brother Henry Corning brought their families to Northern California. In 1994, they started The Springcreek Foundation as a new philanthropic vehicle to continue the Corning tradition of active engagement with philanthropy.

Now in its seventh generation, the Corning and Long families continue to build an intentional legacy, using investment and philanthropic capital to promote positive social change and environmental preservation.
