James S. McDonnell Foundation

**From Global Scientific Research to Local Economic Prosperity** At the James S. McDonnell Foundation, we believe that prosperity must be built — and shared — through strategic, long-term investment in people and ideas. Our mission is to improve economic mobility for St. Louisans facing the starkest disparities by supporting organizations and initiatives that create pathways to opportunity. We take an evidence-based approach, investing in solutions with the potential for measurable impact. We support bold, innovative ideas that remove barriers to progress. We strive for humility and true partnership, recognizing that lasting change happens when we listen first and work alongside those closest to the challenges. These values trace back to our namesake, James S. McDonnell (“Mr. Mac”), who built his company in St. Louis with a belief in rigorous research, a pioneering spirit, and a commitment to people. Today, JSMF applies that same mindset to our philanthropic work — advancing prosperity that works for St. Louis.
