Italian pathologist and hematologist whose contributions to medical science are investigations on the structure and embryology of the kidney, research on the morphology of intestinal villi and haematopoietic studies in normal and pathological conditions. In his research of haematopoiesis, Ferrata helped demonstrate the systemic nature of leukemia, leading him to support an hypothesis that elements of the blood (erythrocytes, leukocytes, and blood platelets) all originate from the hemocytoblast, a direct descendant of a mesenchymal cell, which he referred to as an emoistioblasto (hemohistioblast).
In 1907 he was the first scientist to show that the complement could be split into two components that were singularly inactive, only regaining their activity when reunited.
In 1920 Ferrata founded the journal "Haematologica".
He died on 9 March 1946, aged 65.
