In 1866 Ernst Neumann was appointed professor of pathology and head of the nearly new institute of pathology at
Königsberg (founded in 1865 by R. von Recklinhausen, pupil of R. Virchow).
In
a preliminary communication (Centralblatt für die medizinischen
Wissenschaften, Oct. 10th, 1868), and subsequent papers, Ernst.Neumann
described the presence of nucleated red blood cells in bone marrow
sap of humans and rabbits obtained by squeezing bones. On the basis of
this observation, he was the first to conclude that during
postembryonic life, erythropoiesis is taking place in the bone marrow.
... Former studies by Neumann pointed to the fact that leukocytes are
also formed in the bone marrow. Anticipating the essence of our present
day cognitions, Neumann postulated a common stem cell for all hematopoietic cells (see button hematology and stem_cell).
