Grundriß der menschlichen Erblichkeitslehre und Rassenhygiene (1/2) Menschliche Erblichkeitslehre

The volume offers a systematic presentation of early‑20th‑century ideas about human heredity, variation, and the biological factors that were thought to shape whole populations. Drawing on anatomy, physiology and emerging genetics, the authors lay out a four‑part framework: a general overview of inheritance, a detailed look at racial and individual differences, an inventory of hereditary diseases, and a discussion of the genetic bases of intellectual ability. Illustrated with dozens of figures, the text reflects the scholarly style of its era.

In the second half, the authors turn to what they called “racial hygiene,” proposing that societies could intervene in the course of hereditary change through public policy and personal choices. Modern listeners encounter a historical perspective on eugenic thought, seeing both the scientific ambition and the moral pitfalls that accompanied it. The work serves as a window into the theories that influenced social and political debates before the rise of contemporary genetics.
