First contributors in the history of leukemia

Figure 6 Nikolaus Friedreich (1825-1882). Born in Würzburg in 1825, Nikolaus Friedreich received medical training in this city where his father and grandfather had been professor of medicine. He received his doctorate in 1850. He became Assistant at the clinic of clinician Karl Friedrich von Marcus and in 1853 was habilitated as Privatdocent of special pathology and therapy. When Virchow came to Würzburg, Friedreich became an ardent student of this great pathologist and considered abandoning clinical medicine for pathology. In 1857, he was appointed professor of pathological anatomy at Würzburg, and in 1858 moved to the tenure of professor ordinarius of pathology and therapy at Heidelberg, a post which he held for the remainder of his career. He was also director of medical clinic. He took an interest in all branches of medicine, especially neurology. He has left 8 major and 51 larger and smaller treatises, among them a number of monographs. These include works on leukemia. He died in 1882 from a ruptured aortic aneuvrysm.
