Sculptor Heinz Warneke was born in Germany and studied at the Academy of Fine Arts in Berlin and other German art schools. After immigrating to the United States, he won numerous awards for his work and many commissions. For the National Cathedral in Washington, D.C., he created a granite sculpture, Prodigal Son, in addition to the tympanum and clerestory decoration. Warneke was particularly well known for his animal sculptures, among which was the elephant group for the Philadelphia Zoo. From 1943 to 1968 he taught at the Corcoran School of Art and George Washington University in Washington, D.C.
