The George & Mary Josephine Hamman Foundation concentrates large grants on education and student support, as well as institutional support for schools, medical arts, and conservation causes. Most funding takes the form of big, multi-recipient awards directed toward scholarships for students and operating or capital support for local schools and medical/conservation institutions, suggesting a legacy focus on community institutions in the Houston region.
The George & Mary Josephine Hamman Foundation’s defining pattern is its combination of very large institutional grants and a separate scholarship stream for Houston-area students. In the most recent grant record, the foundation awarded $4,405,000 to various organizations for schools, medical arts, and conservation, showing that it funds multiple community systems at once rather than a single cause. Alongside that institutional support, it also directs substantial resources to individual students through its scholarship program. The grant program description indicates that the foundation makes grants to qualified Texas 501(c)(3) organizations in education, scientific, medical, charitable, and religious fields, including operating and capital needs. Its scholarship activity is explicitly tied to Houston-area high school seniors pursuing undergraduate study, with awards based on academics and financial need. The recent grants list also shows recurring support for these two tracks in successive years, including another large organizational award and another scholarship award in 2023. That mix of broad institutional giving and direct student aid is the clearest picture of how the foundation works.
Education is the foundation’s clearest focus, with one recent award of $4,405,000 to Various Organizations for schools, and another of $1,227,500 to Various Students for scholarships. The scholarship program is aimed at Houston-area high school seniors seeking undergraduate study. Medical-related giving appears in the same institutional funding stream, where the foundation supported medical arts alongside schools and conservation. Conservation is also part of that grouped grantmaking, indicating attention to environmental or land-related institutions as well as educational ones. Beyond those areas, the grant program description includes scientific, charitable, and religious fields, all within Texas. The combination of organization-level support and direct scholarship aid shows a foundation that funds both institutions and individuals in parallel.
Typical grant size is large: the 25th percentile is $1,224,375, the median is $2,694,750, and the 75th percentile is $4,222,750.

Applications for the grant program are submitted online, and supporting documents are uploaded through the application portal. The scholarship program is stated as accepting unsolicited applications.
