In Memoriam - Luther W. Brady, MD 1926-2018
LV Liberty Vision is sad to reflect on the passing of our esteemed colleague and adviser in June of 2018. His insights, sage medical advice and encouragement were essential to the initial years and trajectory of our company. We will keep his patient-centric ethos as a central guiding principle as we go forward.

Luther W. Brady, M.D., one of the world’s foremost radiation oncologists, was Hylda Cohn/American Cancer Society Professor of Clinical Oncology and Professor in the Department of Radiation Oncology at MCP Hahnemann University School of Medicine, Philadelphia, Pennsylvania. Former Chairman of the Department of Radiation Oncology and Nuclear Medicine at Hahnemann University, Dr. Brady stepped down in 1996, having built during a distinguished tenure a department reputed for its teaching excellence and innovative approaches in the treatment of cancer. In June 1996, the University announced establishment of the Luther W. Brady, M.D. Professorship in Radiation Oncology in his honor. The following year, 1997, the Faculty Committee promoted Dr. Brady to the institution’s highest academic rank of University Professor. In 1999, in recognition of exceptional contribution and accomplishment in the field of oncology, the American Medical Association presented Dr. Brady with the AMA Distinguished Service Award Gold Medal. Later that same year, the Philadelphia County Medical Society granted him the 1999 Strittmatter Award, one of the most illustrious honors given for high achievement in the field of medicine. He was a physician with an extraordinary range of interests and activities, both within the discipline of radiation oncology and in his multiple avocations. In spite of extensive commitments throughout the United States and around the world, he emphasized being directly involved in patient care, the teaching of undergraduate medical students and post-graduate training of residents in radiation oncology.
No one in the specialty of radiation oncology has had the breadth and depth of involvement as Dr. Brady. During his career he served as President of every major professional society related to the field, including:
• American College of Radiation Oncology (founding President)
• American Radium Society
• American Society for Therapeutic Radiology and Oncology
• American Board of Radiology
• Inter-Society Council for Radiation Oncology
• Radiological Society of North America
• Society of Chairmen of Academic Radiology Departments
• Society of Chairmen of Academic Radiation Oncology Departments

Dr. Brady was presented the American Cancer Society Cancer Control Award in 1992. One of the most prolific investigators in the history of radiation oncology, Dr. Brady’s publications have ranged from tumors of the eye and orbit, a subject on which he was considered a world authority, to the more common cancers of the breast, lung, cervix, malignant lymphoma, and Hodgkin’s disease. He has over 600 publications to his credit and is co-editor with Carlos A. Perez, M.D. of the landmark textbook, “Principles and Practice of Radiation Oncology,” published in its third edition in 1997. He was Editor-in-Chief of the American Journal of Clinical Oncology and a member of the editorial advisory boards of eleven professional journals.
Dr. Brady was cited in Marquis’ Who’s Who in America; Who’s Who in the World; Who’s Who in the East; Who’s Who in International Medicine; Who’s Who in Frontier & Science Technology; Who’s Who in Cancer Professionals & Facilities; American Men & Women of Science; Who’s Who in the Arts, and International Leaders in Achievement. He was also named in White and Westwood’s “The Best Doctors in America” and in American Health’s publication of “The Nation’s Top M.D.’s - Chosen by Their Colleagues.”
