It is a most profound honor and an unusual privilege for me to be asked to participate in this program in honor of the memory of one of our most distinguished and outstanding radiological colleagues: Ira Hiram Lockwood, 1885–1957. Dr. Lockwood was born in Storm Lake, Iowa; there he received his secondary education and a B.S. degree from Buena Vista College. He obtained his M.D. degree from the General Medical College of Chicago in 1909 and spent the next two years in internship and residency at Flower Hospital in New York, N. Y. Following this, Dr. Lockwood was in general practice at Lincoln, Nebr., until 1916 when he entered the Armed Forces during World War I as a Major. He was first the Chief of the X-Ray Department of Evacuation Hospital Number One, AEF, and later Chief of the Special X-Ray Service of the Second Army, AEF. After the War he returned to his practice in Lincoln. In 1924 Dr. Lockwood became associated with the late Dr. Edward S. Skinner in Kansas City and later formed his own radiological group. He was Chief Radiologist of the Research Hospital and headed the Department of Radiology, Research Clinic. In fact, the formation of this latter group was largely due to his efforts. Other positions include service as Chief of the Residency Program at the Research Hospital, the General Hospital in Kansas City, and also the Veterans Administration Hospitals of Wadsworth, Kans., and Kansas City, Mo. He was Chief Consultant in Radiology to the Veterans Administration in Missouri, Kansas, Arkansas, and Oklahoma. Instrumental in securing radiological residents in the Veterans Ad-ministration Hospitals, he combined this activity with his own residency training program to enhance the practice of radiology in the smaller communities about Kansas City. In this way, his group of younger radiologists provided circuit coverage of the outlying country. Dr. Lockwood was a diplomate of the American Board of Radiology and served from its inception as a Trustee. He also held office as its President and Chairman of the Executive Committee. He became President of the Radiological Society of North America in 1953. He was a Fellow and Past Chairman of the Board of Chancellors of the American College of Radiology. At the time of his death he was President of the College. Both the Radiological Society and the American College of Radiology awarded him gold medals for his outstanding contributions to radiology. Dr. Lockwood was one of the foremost and most prominent exponents of the principle that the medical profession should place good medicine within the reach of everyone, and as a result he was active in the formation of Blue Cross and Blue Shield Plans locally and nationally. His published articles contributing to radiological knowledge numbered in the eighties. He prepared many scientific exhibits, the most notable being, perhaps, his original investigation of radiology of the breast.
