Albert Eulenburg

Albert Eulenburg (August 10, 1840 - July 3, 1917) was a German neurologist who was a native of Berlin. He studied medicine at the Universities of Berlin, Bern and Zurich, and in 1861 earned his doctorate. Among his instructors were Johannes Peter Müller (1801-1858), Ludwig Traube (1818-1876) and Albrecht von Graefe (1828-1870). Later he became a professor of pharmacology at the University of Greifswald, and in 1882, a professor of neurology in Berlin.

Eulenburg is remembered for his written works. His most ambitious work was the multi-volume Real-Encyclopädie der gesammten Heilkunde, which was published in four editions between 1880 and 1914. Later in his career he became interested in the field of sexology, and became co-editor of the journal Zeitschrift für Sexualwissenschaft. In 1913, along with Magnus Hirschfeld (1868-1935) and Iwan Bloch (1872-1922), he founded the Ärztliche Gesellschaft für Sexualwissenschaft und Eugenik. In 1902 Eulenburg penned an influentual work on algolagnia, titled Sadismus und Masochismus (Sadism and Masochism).

Eulenburg was also known for his research concerning the central nervous system, including work involving the vasomotor centers of the brain. He was the first to describe a rare muscular condition known as paramyotonia congenita, which is sometimes referred to as Eulenburg disease.
