“Epidemiology of Surgically Managed Pelvic Organ Prolapse and Urinary Incontinence” (1997), by Ambre L. Olsen, Virginia J. Smith, John O. Bergstrom, Joyce C. Colling, and Amanda L. Clark

In 1997, physicians and researchers Ambre Olsen, Virginia Smith, John Bergstrom, Joyce Colling, and Amanda Clark published, “Epidemiology of Surgically Managed Pelvic Organ Prolapse and Urinary Incontinence,” in the journal Obstetrics and Gynecology. In their article, the authors retrospectively analyzed data from patients who underwent surgery for pelvic organ prolapse or urinary incontinence two years prior in 1995. Often due to a weakening of or damage to their pelvic muscles, women with pelvic organ prolapse can experience a descent of pelvic organs into the lower pelvis and vagina.

Bowen v. Kendrick (1988)

On 29 June 1988, in Bowen v. Kendrick, the US Supreme Court ruled in a five-to-four decision that the 1981 Adolescent Family Life Act, or AFLA, was constitutional. Under AFLA, the US government could distribute federal funding for abstinence-only sexual education programs, oftentimes given to groups with religious affiliations. As a federal taxpayer, Chan Kendrick challenged the constitutionality of AFLA, claiming it violated the separation of church and state.

The Case of Lydia Fairchild and Her Chimerism (2002)

In 2002, after applying for government assistance in the state of Washington, Lydia Fairchild was told that her two children were not a genetic match with her and that therefore, biologically, she could not be their mother. Researchers later determined that the genetic mismatch was due to chimerism, a condition in which two genetically distinct cell lines are present in one body. The state accused Fairchild of fraud and filed a lawsuit against her.

Madison Grant (1865–1937)

Madison Grant was a lawyer and wildlife conservationist who advocated for eugenics policies in the US during the late nineteenth and early twentieth centuries. In his 1916 book, The Passing of the Great Race; or, The Racial Basis of European History, Grant argued that what he called the Nordic race, which originated from northwest Europe, was biologically and culturally superior to all other people, including other Europeans.

George Frederic Still (1868–1941)

George Frederic Still studied pediatrics and childhood conditions in England during the early twentieth century. In Still’s time, pediatrics, or the branch of medicine that focuses on treating and caring for children, remained largely unexplored according to biographer Joseph deBettencourt. Still helped advance pediatrics as a field by classifying and writing about diseases and conditions that arose in children. In 1897, he discovered a unique type of arthritis in children, now referred to as Still’s disease.

"Comfortably, Safely, and Without Shame: Defining Menstrual Hygiene Management as a Public Health Issue" (2015), by Marni Sommer, Jennifer S. Hirsch, Constance Nathanson, and Richard G. Parker

In July 2015, Marni Sommer and colleagues published “Comfortably, Safely, and Without Shame: Defining Menstrual Hygiene Management as a Public Health Issue,” hereafter “Defining MHM,” in American Journal of Public Health. The authors discuss that growing interest in the gender gap in education raised awareness about girls’ obstacles to managing menstruation, especially in low-income countries. Increased focus on MHM pushed menstruation to be redefined as a public issue rather than a private one.

“Survival of Mouse Embryos Frozen to -196 ° and -269 °C” (1972), by David Whittingham, Stanley Leibo, and Peter Mazur

In 1972, David Whittingham, Stanley Leibo, and Peter Mazur published the paper, “Survival of Mouse Embryos Frozen to -196 ° and -269 °C,” hereafter, “Survival of Mouse Embryos,” in the journal Science. The study marked one of the first times that researchers had successfully cryopreserved, or preserved and stored by freezing, a mammalian embryo and later transferred that embryo to a live mouse who gave birth to viable offspring. Previously, scientists had only been successful cryopreserving single cells, like red blood cells.

“The Prophylactic Forceps Operation” (1920), by Joseph Bolivar DeLee

In 1920, Joseph Bolivar DeLee published the article, “The Prophylactic Forceps Operation,” in which he describes how physicians can manually remove a neonate from a laboring woman’s vagina with the use of sedating drugs and forceps. The procedure, according to DeLee, resulted in decreased rates of complications and mortality for both the woman and neonate. DeLee claimed the procedure could reduce damage to the woman such as prolapse, or when internal pelvic organs push down and sometimes protrude from the vagina, and fatal infant brain bleeding.

Planned Parenthood v. Danforth (1976)

On 1 July 1976, the US Supreme Court decided in the case Planned Parenthood v. Danforth that provisions of a Missouri law regulating abortion care were unconstitutional. That law, House Bill 1211, restricted abortion care by requiring written consent for each abortion procedure from the pregnant woman as written consent of the woman’s husband if she was married, or the written consent of her parents if she was unmarried and younger than eighteen. House Bill 1211 also required that physicians make efforts to preserve the lives of aborted fetuses.

Ilya Ilyich Mechnikov (Élie Metchnikoff) (1845-1916)

Ilya Ilyich Mechnikov studied phagocytes, immune function, and starfish embryos in Europe during the late nineteenth and early twentieth centuries. Mechnikov adopted the French form of his name, Élie Metchnikoff, in the last twenty-five years of his life. In 1908, he won the Nobel Prize in Physiology or Medicine with Paul Ehrlich for their contributions to immunology. Mechnikov discovered phagocytes, immune cells that protect organisms by ingesting foreign particles or microorganisms, by conducting experiments on starfish larvae.

"The Inductive Capacity of Oral Mesenchyme and Its Role in Tooth Development" (1969-1970), by Edward J. Kollar and Grace R. Baird

Between February 1969 and August 1970 Edward Kollar and Grace Baird, from the University of Chicago in Chicago, Illinois, published three papers that established the role of the mesenchyme in tooth induction. Drawing upon a history of using tissue interactions to understand differentiation, Kollar and Baird designed their experiments to understand how differentiated structures become specified. Their work overturned a widely accepted model that epithelium controls the identity of the structure, a phenomenon called structural specificity.

Sheldon Clark Reed (1910-2003)

Sheldon Clark Reed helped establish the profession of genetic counseling in the US during the twentieth century. In 1947 Reed coined the term genetic counseling to describe the interaction of a doctor explaining to a patient the likelihood of passing a certain trait to their offspring. With physicians being able to test for genetic abnormalities like cystic fibrosis, Reed helped trained individuals give patients the tools to make informed decisions. In 1955 Reed published the book Counseling in Medical Genetics.
