Jack Joseph & Morton Mandel Foundation
The Jack Joseph & Morton Mandel Foundation is a private independent foundation based in Cleveland, Ohio. Established in 1953 by brothers Jack, Joseph, and Morton Mandel, the foundation has grown into one of the nation's most significant philanthropic organizations. The foundation's origins trace to 1940, when the three brothers pooled $900 to purchase a small auto parts business from their uncle Jacob Mandel, launching Premier Automotive Supply—a company that would become highly successful worldwide. The foundation operates as a non-operating private foundation with a focus on strategic grantmaking and leadership development.
