Purification, characterization and antitumor activity of L-asparaginase isolated from Pseudomonas stutzeri MB-405

During radiology's early years, many people dedicated their lives to developing practical applications for the x-ray. A leader among them was Ed C. Jerman, author of the first textbook on radiographic technique and founder of the organization known today as the American Society of Radiologic Technologists. Through the first three decades of this century, Jerman worked diligently to bring legitimacy, organization and technical expertise to the fledgling profession of radiologic technology. In 1995, the centennial of the x-ray's discovery, it is appropriate to reflect on the many contributions of the man who is remembered today as the father of modern radiologic technology.
