author
1867–1925
A Berlin physician and medical writer, he helped bring early blood science to a wider audience through clear, practical books. His work is closely linked with the rise of hematology around the turn of the twentieth century.

by Paul Ehrlich, Adolf Lazarus
Adolf Lazarus was a German doctor and medical author born in 1867 and deceased in 1925. Surviving library and catalog records connect him with Berlin and with internal medicine, especially the study of blood disorders and anemia.
He is best known today for work associated with Histology of the Blood, Normal and Pathological, written with Paul Ehrlich and later translated into English. Records of his publications also link him to books on anemia, leukemia, and pseudoleukemia, showing a sustained focus on hematology at a time when that field was taking shape.
A later short book on Paul Ehrlich also suggests his role was not only scientific but interpretive: he helped explain important medical ideas and personalities for other readers. For an audiobook audience, he is most interesting as one of those specialist writers whose books preserve the language, methods, and excitement of early modern medicine.
