Dr. Myer Solis-Cohen was a distinguished internist with a specialty in pediatrics. He graduated from the University of Pennsylvania in 1897 and attended the University of Pennsylvania Perelman School of Medicine from which he graduated in 1900. His contributions to the field of medicine reach far beyond his clinical practice as he was deeply involved in the medical affairs at the University of Pennsylvania and the surrounding Philadelphia area. He also served as a former lecturer in Medical Jurisprudence and Toxicology at the Women’s Medical College, the first medical college to educate female physicians. He has authored three books along with over one hundred medical articles, one of which being Woman in Girlhood-Wifehood-Motherhood, which served as an educational tool to inform lectures on women’s health at the Hospital of the University of Pennsylvania, the Philadelphia General Hospital, and the Jewish Hospital.

Woman in Girlhood-Wifehood-Motherhood was written during the advent of obstetric and gynecological innovations. While early medical practices emphasized the supportive role of the physician and midwife during delivery, with the mother at the forefront, more modern practices have altered the narrative of childbirth to be a “partnership” between both the mother and the medical practitioner. This revised conceptualization of childbirth and the expanded role of the physician gained traction during the early to mid-20th century when hospitalization and antenatal intervention became more common practices for pregnant and birthing mothers. This idea reduces the mother to a substitutable vessel, whose behaviors have the potential to be conflicting with the fetus she carries. Woman in Girlhood-Wifehood-Motherhood intends to inform providers about the practices women should carry out during the different stages of pregnancy and womanhood, from menstruation to menopause. The book also includes instructions on conventional child-rearing practices in the early twentieth century and the role of women in marriage. While this book contains useful medical information, cultural interpretations of female physiological phenomena, and societal gender norms remain peppered throughout the literature. | Woman in Girlhood-Wifehood-Motherhood was written during the advent of obstetric and gynecological innovations.

Concluding Remarks
Advancements in Obstetrics and Gynecology Literature
During the early 19th century, high maternal mortality rates affected women of all socioeconomic classes. [1] This coupled with the lack of research conducted in the field of obstetrics and gynecology at the time made childbirth a dangerous task. Across maternity hospitals in parts of Europe such as in England and Wales, two to eight pregnancies out of every one hundred would result in the death of a pregnant mother.[1] Around this time, “midwifery”became a compulsory field of study for medical students in Scotland and England. [1] As a result, increasing amounts of publications regarding new practices in the field of women’s reproductive health were produced and circulated in parts of Europe.[1] These practices often aimed to reduce the risk associated with puerperal fever, a postpartum infection, and were adopted throughout the majority of British and American hospitals.[1] The far-reaching influence of these early works serves as a testament to the importance of the widespread dissemination of scientific literature, especially in the field of reproductive health. Works such as Woman in girlhood-wifehood-motherhood: her responsibilities and her duties at all periods of life: a guide in the maintenance of her own health and that of her children by Myer Solis-Cohen could be consumed by both medical professionals and the general populace alike. Therefore, they performed as an invaluable tool during an age when women were far less likely to receive proper gynecological care or have access to the proper resources to educate themselves about how to maintain their physical and mental well-being. While these publications are not perfect, they are an important part of the emergence of reproductive care practices and have played an integral role in shaping the way we treat women’s health today.
