Ernst Grawitz (18 March 1860, Mittelhagen, Kreis Greifenberg - 11 July 1911) was a German internist remembered for his work in the field of hematology. He was a younger brother of pathologist Paul Grawitz (1850-1932).
He studied medicine in Berlin, earning his degree in 1882. Following graduation, he served as a military physician, subsequently working as a prosector at the Augusta Hospital (Auguste-Viktoria-Klinikum) in Berlin (1886-1889). Afterwards, he was an assistant at the Berlin-Charité.
In 1890 he was habilitated for internal medicine, becoming an associate professor in 1897 as well as chief physician at the city hospital (Städtischen Krankenhaus) in Charlottenburg.[1]
