In 1861, William John Little published, “On The Influence of Abnormal Parturition, Difficult Labors, Premature Birth, and Asphyxia Neonatorum, on the Mental and Physical Condition of the Child, Especially in Relation to Deformities,” hereafter “Abnormal Parturition,” in the Transactions of the Obstetrical Society of London. In the article, Little discussed the causes and types of what he refers to as abnormal births, and theorized how those births affect an infant’s likelihood of exhibiting a deformity. Little defined abnormal births as those involving an atypical maternal or fetal presentation, such as a slow birthing process or a fetus exiting the birth canal feet first rather than head first. In his article, Little published one of the first definitional frameworks to describe a condition causing rigidity and stiffness in the limbs that is often associated with birth-related trauma, which was then called Little’s disease, but is modernly known as spastic Cerebral Palsy.

The March of Dimes Foundation, or the March of Dimes, is a non-profit organization headquartered in Arlington, Virginia, focused on the health of pregnant women and infants in the US. Former United States president Franklin Delano Roosevelt founded the March of Dimes, then called the National Foundation for Infantile Paralysis, in 1938 to address polio. Polio is a viral illness that infects the spinal cord and may lead to paralysis. Roosevelt contracted polio in 1921, which left him permanently paralyzed from the waist down. During the 1960s, after scientists introduced polio vaccines, March of Dimes shifted its focus to prevent preterm birth and birth defects. As a non-profit organization, March of Dimes provides community service, funds for research, and efforts to educate the public about preterm birth and birth defects. While March of Dimes’ original goal was to help reduce the spread of polio in the US, it was also one of the first organizations to lead a campaign to prevent birth defects and infant mortality.

William John Little was one of the first orthopedic surgeons to research congenital malformations and their causes in the nineteenth century and presented preliminary research on a condition modernly known as cerebral palsy, a condition of varying severity that affects a person’s ability to move. Little worked throughout the United Kingdom for the majority of the time he practiced medicine, and eventually founded one of the first orthopedic infirmaries, the Royal Orthopedic Hospital in London, England. Throughout his career, Little studied congenital malformations, which are medical conditions inherited before birth, as well as how certain medical circumstances during delivery affect the neonate. In 1861, he described a condition with motor, behavioral, and cognitive irregularities in neonates, linked with oxygen deprivation during birth. Little’s research on that condition, originally called Little’s disease, and modernly, spastic cerebral palsy, was one of the first accounts of cerebral palsy in infants.

Albert William Liley advanced the science of fetal physiology and the techniques of life-saving in utero blood transfusions for fetuses with Rh incompatibility, also known as hemolytic disease. Due to his advances, fetuses too young to survive premature delivery, and likely to die in utero if their Rh incompabilities were left untreated, were successfully transfused and carried to term. Liley was as passionate as a clinician and researcher as he was about his views on the rights of the unborn.

In the fifteen years between the discovery of fetal alcohol syndrome, or FAS, in 1973 and the passage of alcohol beverage warning labels in 1988, FAS transformed from a medical diagnosis between practitioner and pregnant women to a broader societal risk imbued with political and cultural meaning. In this dissertation, I examine how scientific, social, moral, and political narratives dynamically interacted to construct the risk of drinking during pregnancy and the public health response of health warning labels on alcohol.

In 1616 in Padua, Italy, Fortunio Liceti, a professor of natural philosophy and medicine, wrote and published the first edition of De Monstruorum Causis, Natura et Differentiis (On the Reasons, Nature, and Differences of Monsters), hereafter De monstruorum. In De monstruorum, Liceti chronologically documented cases of human and animal monsters from antiquity to the seventeenth century. During the seventeenth century, many people considered such monsters as frightening signs of evil cursed by spiritual or supernatural entities. Liceti categorized monsters based on their potential causes, several of which he claimed were unrelated to the supernatural. Historians later noted that some documented monsters were infants with birth defects. In De monstruorum, Liceti elevated the status of monsters to potential subjects of scientific inquiry and provided an early model for the study of birth defects, a field later called teratology.

Sir John Bertrand Gurdon further developed nuclear transplantation, the technique used to clone organisms and to create stem cells, while working in Britain in the second half of the twentieth century. Gurdon's research built on the work of Thomas King and Robert Briggs in the United States, who in 1952 published findings that indicated that scientists could take a nucleus from an early embryonic cell and successfully transfer it into an unfertilized and enucleated egg cell. Briggs and King also concluded that a nucleus taken from an adult cell and similarly inserted into an unfertilized enucleated egg cell could not produce normal development. In 1962, however, Gurdon published results that indicated otherwise. While Briggs and King worked with Rana pipiens frogs, Gurdon used the faster-growing species Xenopus laevis to show that nuclei from specialized cells still held the potential to be any cell despite its specialization. In 2012, the Nobel Prize Committee awarded Gurdon and Shinya Yamanaka its prize in physiology and medicine for for their work on cloning and pluripotent stem cells.

Francesco Redi, son of Florentine physician Cecilia de' Ghinci and Gregorio Redi, was born in Arezzo, Italy, on 18 February 1626. He studied philosophy and medicine at the University of Pisa, graduating on 1 May 1647. A year later, Redi moved to Florence and registered at the Collegio Medico. There he served at the Medici Court as both the head physician and superintendent of the ducal pharmacy and foundry. Redi was also a member of the Accademia del Cimento, which flourished from 1657-1667. It was during this decade that Redi produced his most important works.

As one of the researchers involved in the development of the oral contraceptive pill, Min Chueh Chang helped to revolutionize the birth control movement. Although best known for his involvement with "the pill," Chang also made a number of discoveries throughout his scientific career involving a range of topics within the field of reproductive biology. He published nearly 350 articles in scientific journals. His dedication to his work left him with little time for family responsibilities, although shortly after his arrival in the United States in 1951, Chang married Isabelle Chin, an American-born Chinese woman with whom he would later have three children.

William Stewart Halsted was a surgeon at Johns Hopkins Hospital in Baltimore, Maryland, during the late 1800s and early 1900s. In 1894 Halsted described his procedure for treating breast cancer by removing the breast tissue, chest muscles, and lymph nodes in the armpit, a procedure he named radical mastectomy, and that became the standard of care for treating breast cancer until 1970. He also made contributions to other novel medical procedures such as gallbladder surgery, blood transfusions, antiseptic techniques, anesthesia use, and using plates and screws to hold bones in position when setting bone fractures. At Johns Hopkins Hospital, Halsted established a surgical training program in which he allowed medical students and surgical residents to shadow him and perform procedures under his guidance. In the twentieth century, similar training programs spread across the country and informed the standardization of medical training. Halsted devised a surgical treatment for breast cancer and reshaped the way physicians practiced medicine in the twentieth century, which resulted in better health outcomes through more careful surgical methods, especially in women with breast cancer.
