[I]n 1944 [he] identified a rare condition in which two patients experienced a thickening of their blood serum, bleeding of the mouth, nose, and blood vessels of the retina, low red blood cell and platelet counts, high erythrocyte sedimentation rates, and lymph node involvement. Bone marrow biopsies showed an excess of lymphoid cells and bone X-rays were normal, excluding a diagnosis of multiple myeloma. Both patients also had a large amount of a single unknown blood protein with an extremely high molecular weight, a "macro" globulin.
