Ludwig Traube was a son of a Jewish wine merchant. In 1835, at age 17, he left the gymnasium in Ratibor. He studied medicine in Breslau, Berlin and Vienna. Among his teachers were Jan Evangelista Purkyně and Johannes Müller. Besides medicine, he was very active in philosophical studies; he especially appreciated the philosophy of Spinoza. In 1840 he received his doctorate, a work about pulmonary emphysema. Then he moved to Vienna to broaden his knowledge und Joseph Škoda. Since 1841 he was assistant of a physician for paupers in Berlin. In 1848 he became an unsalaried lecturer and in 1849 the first civilian assistant of Johann Lukas Schönlein at the Charité. Ludwig Traube was involved as physician during the revolutionary occurrences in 1848. The later well-known botanist Nathanael Pringsheim, who was a friend of Traube, was arrested during the fighting. Another friend of Pringsheim was severely wounded, but saved by the help of Ludwig Traube. In 1853 Traube became the leading physician of the pulmonary department at the Charité and later chief of the propaedeutic clinic. He was also teacher at the military-medically seminaries. At the hospital of the Jewish community in Berlin he was head physician of the internal medicine department. Traube's Jewish ancestry was a great handicap for his career, but despite this he became in 1857 an adjunct professor, and in 1862 ordinary professor at the Friedrich-Wilhelms-Institute in Berlin. In 1866 he got the title “Geheimer Medizinalrath” and in 1872 he was appointed a professor at the University of Berlin. Ludwig Traube had a coronary disease, which led to death. His grave is at the Jewish cemetery Berlin Schönhauser Allee. Ludwig Traube was the elder brother of Moritz Traube, who was an extraordinary private scholar and a pioneer of physiological chemistry. The Berlin physician Moritz Litten was his son-in-law. Ludwig Traube married Cora Marckwald, and they had 3 daughters and 2 sons. It was an impressing happening, when a son died from diphtheria the age of 5 years. Another son, Ludwig Traube, was a palaeographer. His nephews Wilhelm Traube and Albert Fraenkel belong also to the scholars-family Traube-Litten-Fraenkel.

He investigated the pathophysiology of respiration and the regulation of the body temperature, and gave a scientific basis to digitalis therapy.
