...A lifetime of achievement in cellular immunity The Robert Koch Foundation awarded the Robert Koch Gold Medal to Dr. Emil R. Unanue (71), Mallinckrodt Professor and Chairman of the Department of Pathology and Immunology, Washington University School of Medicine, St. Louis, Missouri, USA.

lifetime, which have focused on cellular immunity to bacterial disease pathogens and protein antigens.Unanue
