As part of the 20th anniversary of the Journal of Diagnostic Medical Sonography, the editorial board is initiating this symposium to honor and remember those who have supported, influenced, and defined the profession of sonography. The initial column honors Kenneth Taylor, MD, PhD, an academic radiologist known throughout the world for expanding the applications of diagnostic medical sonology. Dr. Taylor was educated in England, where he received PhD and MD degrees. He initially practiced surgery but became fascinated with the potential of sonographic imaging. He completed a fellowship in ultrasound and nuclear medicine and wrote a medical thesis on the diagnosis of hepatobiliary disease using gray-scale sonography in 1975. In 1979, he joined the Yale University School of Medicine, where he remained until his untimely death in February 2003. Dr. Taylor was author of more than 200 scientific articles and numerous textbooks. His projects and research extend from 1974 to 2003 and include articles on hepatobiliary and pelvic sonography, abdominal and pelvic vasculature, sonomammography, ovarian cancer screening, and sonographic contrast agents. Most sonographers practicing today use measurements and protocols initiated and refined by Dr. Taylor. Dr. Taylor worked closely with the Society of Diagnostic Medical Sonography (SDMS) and the Joint Review Committee on Education in Diagnostic Medical Sonography (JRC-DMS) in the development of standards for sonography education. His perceptions of sonography influenced others. The legacy that Dr. Taylor left for sonographers is far greater than the specifics of clinical practice. It is a legacy that we hope to share with you though this collection of tributes to and writings by Dr. Taylor.
