Myasthenia gravis pseudoparalytica gained its formal medical designation through the rigorous clinical investigation of Friedrich Jolly. A central figure in German neurology during the late nineteenth century, he systematically bridged the gap between psychiatric practice and physical diagnostic procedures, ultimately transforming how practitioners approach neuromuscular fatigue and electrical diagnostic resistance within the human body.
Academic Foundation and Early Appointments
Born in Heidelberg in 1844, Friedrich Jolly held citizenship in the Grand Duchy of Baden. He pursued his medical education at the University of Göttingen, studying under the guidance of Georg Meissner. Following the receipt of his doctorate from Ludwig-Maximilians-Universität München in 1867, he entered the clinical environment. By 1868, he served as an assistant to Bernhard von Gudden and Hubert von Grashey at the mental institution in Werneck. He later moved to the University of Würzburg in 1870, working under Franz von Rinecker at the Juliusspital.

The professional trajectory of Jolly involved leading major psychiatric institutions. In 1873, he assumed the role of director at the psychiatric clinic in Strasbourg, succeeding Richard von Krafft-Ebing. His career reached a significant milestone in 1890 when he accepted the position of director at the neuropsychiatric clinic of the Charité in Berlin. In this capacity, he replaced Karl Friedrich Otto Westphal, solidifying his role within the academic hierarchy of the Humboldt-Universität zu Berlin.
Contributions to Neurological Science
Jolly produced substantial research concerning the physiological mechanisms of myasthenia gravis, specifically identifying the abnormal muscle fatigue patterns that define the condition. His work established the diagnostic basis for what is now known as Jolly's test. Beyond neuromuscular research, he published a definitive treatise on hypochondria within the collection of Hugo Wilhelm von Ziemssen. His 1884 work, Untersuchungen über den elektrischen Leitungswiderstand des menschlichen Körpers, provided a framework for the application of electrical diagnostics in clinical medicine.
