The Ewing Halsell Foundation, based in San Antonio, is a private charitable trust dedicated to improving the quality of life for Texans by providing access to the arts, education, and quality health care, and by helping provide opportunities for the economically disadvantaged. The foundation, established in 1957 by Ewing Halsell and his wife, Lucile, has an endowment of $22 million and a grant-making level of $1.5 to $2 million a year. The endowment was built from the estates of the Halsells and from gifts from other family members such as Grace Rider, Lucile Halsell's sister. The foundation's trustees consist of Halsell family members and business associates. They are supported in their work by a grants administrator, a secretary-bookkeeper and a land manager. Ewing Halsell Foundation grants have included the first grant to establish the South Texas Medical Center and funding to rescue the Lone Star Brewery for reuse as the San Antonio Museum of Art. It has also made grants to underwrite the first Immigration Reform Study, and, more recently, to establish San Antonio's Botanical Gardens. The Ewing Halsell Foundation is a member of the Conference of Southwest Foundations.
