In 1873 Italy, Camillo Golgi created the black reaction technique, which enabled scientists to stain and view the structure of neurons, the specialized cells that compose the nervous system. During the nineteenth century, scientists were studying cells and proposed cell theory, which describes the basic characteristics of cells as fundamental units of life. However, cell theory struggled to explain neurons as they are specialized cells and more complex in structure than cells of other tissues. Prior to Golgi’s black reaction, other neuron staining techniques did not enable scientists to clearly and completely view entire neurons without damaging the tissue and obscuring the form. By enabling scientists to study individual neurons and neural tissues, Golgi’s black reaction enables researchers to better study the nervous system and how it develops.
John Hunter studied human reproductive anatomy, and in eighteenth century England, performed one of the earliest described cases of artificial insemination. Hunter dissected thousands of animals and human cadavers to study the structures and functions of organ systems. Much of his anatomical studies focused on the circulatory, digestive, and reproductive systems. He helped to describe the exchange of blood between pregnant women and their fetuses. Hunter also housed various natural collections, as well as thousands of preserved specimens from greater than thirty years of anatomy work. Hunter's work developed practices in reproductive and reparative surgery and furthered the study of human anatomy and physiology.
Charles Knowlton was a physician and author who advocated for increased access to information about reproduction in the nineteenth century in the US. Throughout his early medical education, Knowlton was particularly interested in anatomy and on several instances robbed graves for bodies to dissect. In 1832, Knowlton authored The Fruits of Philosophy, a pamphlet that contained detailed descriptions of the reproductive organs and information on conception and methods to control reproduction. Knowlton circulated his work among his patients until it was republished in Boston, Massachusetts, in 1832. For publishing a book on sex and methods of birth control, Knowlton was convicted of breaking obscenity laws, which prevented the transmission of obscene materials. After his death, social activists Charles Bradlaugh and Annie Besant republished his work in London, England. Knowlton’s writing about sex and birth control allowed individuals to understand and take control of their reproduction and initiated a public discussion about obscenity laws.
Renate Blumenfeld-Kosinski published Not of Woman Born in 1990. The book is a historical account of the cesarean birth procedure, hereafter c-section, during the Renaissance in Europe. A c-section is a surgical procedure that medical professionals use to deliver a fetus through an incision in a pregnant person’s abdomen. During the medieval and Renaissance periods, midwives performed c-sections on pregnant women after they had died when there was a chance that the fetus was still alive. They did this so the midwife could get the baby baptized, enabling it to be buried in sacred ground after death. Not of Woman Born traces how the procedure evolved in the late fifteenth and sixteenth century to be more commonly performed by male surgeons, rather than midwives, to save both the mother and the fetus. Blumenfeld-Kosinski provides historical, religious, and cultural context for understanding how people viewed and practiced c-sections in Europe during medieval and Renaissance times, in contrast to how people view and rely on the widespread delivery procedure in modern times.
