Otto Lubarsch (1860-1993)

Otto Lubarsch (January 4, 1860 - 1933) was a German pathologist who was a native of Berlin.

He originally studied philosophy and natural sciences in Leipzig and Heidelberg, and later earned his medical degree in Strasbourg in 1883. Subsequently he was an assistant to Hugo Kronecker (1839-1914) at the Institute of Physiology in Bern, and afterwards an assistant at the pathological institutes of Giessen, Breslau and Zurich. In 1891 he became first assistant to Albert Thierfelder (1842-1908) at the pathological institute at the University of Rostock, where in 1894 he was appointed an associate professor of pathological anatomy and general pathology. In 1905 he became director of the institute of pathology and bacteriology at Zwickau, and later served as a professor in Düsseldorf (from-1907), Kiel (from-1913), and Berlin (1917-1929).

In 1888 Lubarsch provided the first detailed description of carcinoid tumors during autopsies of two male "patients",^[1] however it wouldn't be until 1907 that the term karzinoid was applied by Siegfried Oberndorfer (1876-1944). Lubarsch also discovered tiny crystals in the epithelial cells of the testis that resemble sperm crystals. These structures are now known as Lubarsch' crystals.

With Friedrich Henke (1868-1943), he was editor of the Henke-Lubarsch Handbuch der Speziellen Pathologischen Anatomie und Histologie, which was a massive reference book containing information germane to pathology. It was founded in 1924, and produced over a forty year span. After World War II, it was continued and edited by Robert Rössle (1876-1956). Also with veterinarian Robert von Ostertag (1864-1940) he collaborated on the journal Ergebnisse der allgemeinen Pathologie und pathologischen Anatomie der Menschen und der Tiere.
