Producing development: The anatomy of human embryos and the norms of Wilhelm His.

In 1875 the Göttingen anatomist Wilhelm Krause described what was briefly the most famous but soon became the most notorious human embryo of the last quarter of the nineteenth century. It was presented as deciding a heated controversy over embryology and evolution, but its status was debated in dozens of publications—until in 1882 anatomists finally agreed that it was the embryo, not of a human being at all, but of a bird. I shall reconstruct the remarkable history of Krause’s embryo, but my larger concern is with the enterprise to which it fell victim: the making of modern human embryology. This was the achievement, above Producing Development: The Anatomy of Human Embryos and the Norms of Wilhelm His
