Albert Jesionek


Albert Jesionek was a German dermatologist.
He studied medicine at the universities of Kiel, Tübingen and Munich, where in 1894 he received his doctorate. After graduation, he spent several years working as an assistant at the municipal hospital in Munich, and from 1900 served as a deputy senior physician at the dermatology clinic in Munich under Karl Posselt. In 1906 he became an associate professor, and later the same year relocated to the University of Giessen, where in 1913 he was appointed director of the Lupusheilstätte. In 1918 he was named a full professor of dermatology at the university.
He is remembered for his work involving light-therapy for the treatment of skin tuberculosis. He recognized the importance of early studies done by Joseph Doutrelepont and Niels Ryberg Finsen in regards to light-therapy treatment for lupus and skin tuberculosis; and with Hermann von Tappeiner and Albert Jodlbauer at Munich, he had taken part in research of light from a biological standpoint. In 1910 he published a monograph on the latter subject titled "Lichtbiologie", followed by "Lichtbiologie und Lichtpathologie" two years later.
From 1920 onward, he was involved with issues such as the pathogenesis of skin tuberculosis, the curative effect of tuberculins and the treatment of skin tuberculosis from a dietary standpoint, namely the "Sauerbruch-Herrmannsdorfer-Gerson diet".
A specialized irradiation lamp known as a "Jesionek lamp" is named after him.
