HANNA, LEONARD C., JR. (5 Nov. 1889-5 Oct. 1957), a philanthropist who, during his lifetime, contributed over $90 million to cultural and charitable institutions; and a director of the M. A. HANNA & CO., was born in Cleveland to Leonard and Coralie (Walker) Hanna. He attended University School, Hill School in Pottstown, Pa., and Yale University. After graduation from Yale, he worked in the iron and steel industry to gain experience. He then served with the Army Signal Corps in WORLD WAR I. After the war he returned to Cleveland and was admitted to the partnership of M. A. Hanna & Co. (which later became Hanna Mining) in 1917.
