However, there is a notable Mattie Beal Memorial High School which is named after Mattie Beal, a prominent businesswoman, civic leader, and philanthropist who supported education and community welfare in the city of Lawton, Oklahoma. She was the founder of the Beal Bank, which eventually became one of the largest privately-owned banks in the country. Mattie Beal was also active in various social and cultural organizations and served as the first female president of the Lawton Chamber of Commerce. She passed away in 1971, but her legacy continues through the Mattie Beal Foundation and various charitable initiatives that support her vision for a better community.
