The Clyde and Summer Anderson Foundation concentrates its giving on large benevolent gifts to major medical institutions and research organizations, with smaller occasional support for religious ministry. Most dollars go to hospital systems and university medical centers for general philanthropic support, with targeted funding toward vision research and a local church in Birmingham.
Highly concentrated giving: very few, large one-time grants directed primarily to established medical institutions and research organizations, with an occasional smaller gift to a local religious organization.
The Clyde and Summer Anderson Foundation’s largest recent gift was a $500,000 benevolent donation to Cleveland Clinic Foundation. That single grant captures a pattern that runs through the foundation’s recent filings: substantial, unrestricted support for major medical institutions, paired with smaller gifts to a mix of community, education, culture, and faith-based organizations. In 2024, the foundation also gave $250,000 to Medical University of South Carolina Foundation, another broad philanthropic gift to a university-linked medical center. Health-related giving sits at the center of the foundation’s profile. Foundation Fighting Blindness received $50,000 in 2023, and Alabama Kidney Foundation received repeat support in both 2023 and 2024. Beyond medicine, the foundation’s grants reached Charleston Day School, Charleston Literary Festival, Preservation Society of Charleston, and Grace Church, showing that its checkbook extends beyond one sector while still favoring established institutions. The foundation’s stated grant type across these awards is benevolent donation, and its recent awards include both very large commitments and much smaller community-level gifts. That combination points to a funder that uses discretionary, general-purpose support rather than narrowly restricted project grants.
Medical philanthropy is the clearest throughline. The foundation gave $500,000 to Cleveland Clinic Foundation in 2023 and $250,000 to Medical University of South Carolina Foundation in 2024, both described as benevolent donations. Vision and blindness-related work also appears in the record. Foundation Fighting Blindness received $50,000 in 2023, aligning with the foundation’s support for vision research and blindness prevention. In community and civic giving, the foundation backed Charleston institutions such as Charleston Day School with $36,945 in 2023 and $35,154 in 2024, plus Preservation Society of Charleston with $35,000 in 2023 and $30,000 in 2024. It also supported Grace Church with $75,000 in 2024 and $20,000 in 2023, indicating a pattern of repeated support for selected local organizations.
Typical award size sits at $7,500 at the 25th percentile, $15,000 at the median, and $25,250 at the 75th percentile. The distribution is uneven because the foundation also makes occasional much larger gifts, including six-figure benevolent donations. Several recipients appear in more than one year, including Do for One, Alabama Kidney Foundation, Charleston Day School, Preservation Society of Charleston, Charleston Literary Festival, and Grace Church. The foundation is a private grantmaker with no program-related investments and no funding to individuals. The grant descriptions consistently label awards as benevolent donations, suggesting discretionary general support rather than a formal application-driven project program.
