Erich Wilhelm Heinrich Kallius (3 August 1867, in Berlin – 1 January 1935, in Heidelberg) was a German anatomist.
He received his education at the Universities of Berlin and Göttingen, earning his medical doctorate in 1892.
As a student, he had as instructors, Heinrich Wilhelm Gottfried von Waldeyer-Hartz in Berlin and Friedrich Sigmund Merkel at Göttingen.
His primary areas of work included studies on the development of the tongue and of the thyroid gland.
[3] He is credited with introducing a method of "fixing" Golgi stains so that contrast-stains could be employed with them and the specimens protected by cover-slips.
