Justine Johnstone (January 31, 1895 – September 4, 1982) was an American stage and silent screen actress. She was later a pathologist and expert on syphilis. Working under her married name, Justine Wanger, she was part of the team that developed the modern intravenous drip technique.[1]

Acting career[edit]

She attended Emma Willard School in Troy, New York. An original performer in the Ziegfeld Follies and a performer in the Folies-Bergere, she appeared in the 1917 Broadway production Over the Top, which starred Fred Astaire.[1]

Medical career[edit]

Johnstone married producer Walter Wanger on 13 September 1919; they divorced in 1938.[2] She retained her married name and had borne Wanger no children.

After giving up performing, Wanger 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.[1][3] She later studied and made developments in endocrinology and cancer research and installed a laboratory in her house in Hollywood.[1]


Justine Wanger died in Santa Monica, California from congestive heart failure, aged 87. Her remains are at Chapel of the Pines Crematory.
