Justine Johnstone-After giving up performing in film and as a Ziegeld girl, she enrolled in Columbia University, where she studied plant research and served as a research assistant to Samuel Hirshberg and Harold T. Hyman. The team developed the modern I.V. unit; their key breakthrough was to slow down the rate of delivery and avoid what was then known as “speed shock” by introducing the now-ubiquitous drip technique. She later studied and made developments in endocrinology and cancer research and installed a laboratory in her house in Hollywood.
