Biography of Josef Arneth
Josef Arneth studied medicine at the universities of Munich, Heidelberg and Würzburg. He was conferred doctor of medicine in Würzburg in 1897 and subsequently became assistant at the clinic of syphilis at the clinic of medicine. In 1904 he became Privatdozent (professor?) of internal medicine in Würzburg. In 1907 he became honorary professor of medicine as well as director of he Municipal Hospital in Münster from 1907. He held this tenure until 1944.
Arneth was an active researcher in haematology and published several books on the subject of diseases of the blood and pulmonary tuberculosis. He demonstrated five groups of polymorphonuclear leucocytes in normal blood and advocated the estimation of these groups as a valuable aid in the determination of bone-marrow reaction to infective and other agents.
Much of his theoretical work was, however, strongly criticised and found little acceptance. He is, though, considered one of the pioneers of German haematology.
