Dr Dudrick’s ground- breaking research in the effcacy of intravenous feeding is recognized as one of the 3 most important advances in modern surgery. Dr Dudrick’s research, frst published in 1968, and his continuing commitment to the development of parenteral nutrition (PN), has transformed the care of acutely ill pa- tients and saved the lives of millions of children and adults. “With the passing of Dr Dudrick, medicine has lost one of its most inspirational leaders,” said ASPEN President Lingtak-Neander Chan, PharmD. “Dr Dudrick’s legacy goes far beyond his pioneering research. While he contin- ued as the seminal scientist in the development of PN, throughout his life he also chaired the surgery depart- ment at 4 institutions, authored textbooks and hundreds of journal articles, and taught and mentored countless physicians and other healthcare providers. Dr Dudrick will be remembered as a healer and visionary, whose kindness has deeply touched many people, and whose achievements have changed the lives of many.” “Dr Dudrick truly nourished other medical and health- care professionals. He always found the time to meet with physicians, scientists, clinicians, and students from around the world to answer questions about his research and nutrition. ASPEN’s archives are flled with letters of appreciation—and wonder—at his generosity, knowledge, and compassion,” said Marion Winkler, PhD, RD, Pres- ident of the ASPEN Rhoads Research Foundation and ASPEN’s 30th president. A tireless proponent of the importance of the science of nutrition, Dr Dudrick was one of the 35 healthcare professionals who worked together in 1975 to create ASPEN as an interdisciplinary association founded for the purpose of providing optimal nutrition to all people. “ASPEN’s interdisciplinary membership and approach refect one of the principles that guided Dr Dudrick’s life and marked his brilliant and life-changing career,” said ASPEN’s 8th president, Ezra Steiger, MD. “He practiced collaboration from the earliest days of his research when he reached out to other physician specialists, basic scientists, pharmacists, nurses, dietitians, and medical suppliers.” “ASPEN also continues Dr Dudrick’s commitment to scientifc research and advancement through its educational programs and journal publications that he championed,” said Marion Winkler. “In addition, each year the Dudrick Research Scholar Award is presented to a mid-career sci- entist who is contributing to our understanding and the advancement of nutritional support.” ASPEN is far from alone in recognizing Dr Dudrick’s contributions to medical research, education, and clinical practice.
