Stanley Paul Leibo (1937–2014) Risa Schnebly Stanley Paul Leibo studied the cryopreservation of embryos in the US in the twentieth century. Cryopreservation is a method of preserving biological material through freezing. Early in his career, Leibo collaborated with other scientists to study why cells were oftentimes injured during freezing. Later, Leibo and his team accomplished one of the first successful births using previously-frozen mammalian embryos. 2021-02-05 5 Feb 2021 - 8:36:07am
Thesis: Dismantling Legal Constraints to Contraception in the 1900s Lakshmeeramya Malladi In the late nineteenth century, the Comstock Act of 1873 made the distribution of contraception illegal and classified contraception as an obscenity. Reflecting the predominant attitude towards contraception at the time, the Comstock Act was the first federal anti-obscenity law that targeted contraception. However, social acceptance of birth control changed at the turn of the twentieth century. In this thesis, I analyzed legislation, advocates, and literature pertinent to that social change to report on the events leading up to the decriminalization of contraception. 2021-01-27 27 Jan 2021 - 7:59:31pm
Minnie Joycelyn Elders (1933–) J. Nalubega Ross Minnie Joycelyn Elders, known as Joycelyn Elders, is a pediatrician and professor at the University of Arkansas for Medical Sciences in Little Rock, Arkansas. In 1953, Elders began to work with the US Army, where she trained as a physical therapist, being the only African American woman in her training class. Elders eventually became a medical doctor in 1956, specializing in pediatric endocrinology. In 1993, then US President Bill Clinton appointed Elders as the Surgeon General for the United States Public Health Service Commissioned Corps, which she served as until 1994. 2021-01-15 15 Jan 2021 - 8:20:47pm
Thesis: The Hwang Woo-Suk Scandal and the Development of Bioethics in South Korea Anne Clay In 2004, the South Korean geneticist Woo-Suk Hwang published what was widely regarded as the most important research finding in biotechnology that year. In the prestigious American journal Science, he claimed that he had succeeded in cloning a human blastocyst, which is an embryo in its early developmental stages (Hwang et al. 2004). A year later, in a second Science article, he made the earth-shattering announcement that he had derived eleven embryonic stem cell lines using his cloning technique (Hwang et al. 2005). The international scientific community was stunned. 2020-11-26 28 Nov 2020 - 1:04:37am
James Edgar Till (1931– ) Ajeet Bains James Edgar Till is a biophysicist known for establishing the existence of stem cells along with Ernest McCulloch in 1963. Stem cells are undifferentiated cells that can shift, or differentiate, into specialized types of cells and serve as a repair system in the body by dividing indefinitely to replenish other cells. Till’s work with stem cells in bone marrow, which produces the body’s blood cells, helped form the field of modern hematology, a medical discipline that focuses on diseases related to the blood. 2020-11-20 21 Nov 2020 - 1:17:06am
Dissertation: Lessons from Embryos: Haeckel’s Embryo Drawings, Evolution, and Secondary Biology Textbooks Karen Linette Wellner Haeckel believed that the development of an embryo revealed the adult stages of the organism’s ancestors. Haeckel represented this idea with drawings of vertebrate embryos at similar developmental stages. This is Haeckel’s embryo grid, the most common of all illustrations in biology textbooks. Yet, Haeckel’s embryo grids are much more complex than any textbook explanation. I examined 240 high school biology textbooks, from 1907 to 2010, for embryo grids. 2020-11-06 6 Nov 2020 - 8:55:53pm
Thesis: Leo Kanner and the Psychobiology of Autism Sean Cohmer This thesis illustrates that Kanner held an explicitly descriptive frame of reference toward his eleven child patients, their parents, and autism. Adolf Meyer, his mentor at Johns Hopkins, trained him to make detailed life-charts under a clinical framework called psychobiology. By understanding that Kanner was a psychobiologist by training, I revisit the original definition of autism as a category of mental disorder and restate its terms. 2020-11-03 4 Nov 2020 - 12:25:11am
Peter Mazur (1928–2015) Risa Schnebly Peter Mazur was a researcher in the US who developed new ways of preserving biological material by freezing it, a process called cryopreservation. If done correctly, cryopreservation enables scientists to store or study biological material for an extended period of time. If done incorrectly, cryopreservation can easily harm or destroy biological material. Mazur worked to find the best ways to cryopreserve different cells, embryos, and organs in order to minimize the damage caused by freezing. 2020-10-13 13 Oct 2020 - 11:01:31pm
Henrietta Lacks (1920–1951) Rohini Nott Henrietta Lacks, born Loretta Pleasant, had terminal cervical cancer in 1951, and was diagnosed at The Johns Hopkins University in Baltimore, Maryland, where researchers collected and stored her cancer cells. Those cells went on to become the first immortal human cell line, which the researchers named HeLa. An immortal cell line is an atypical cluster of cells that continuously multiply on their own outside of the organism from which they came, often due to a mutation. 2020-10-09 9 Oct 2020 - 7:19:07pm
Vincenz Czerny (1842–1916) Margaret Zheng Vincenz Czerny was a surgeon in the nineteenth century who specialized in cancer and women’s surgical care. Czerny performed one of the first breast augmentations using a reconstruction method to correct asymmetry and disfigurement of a woman’s breasts. Additionally, Czerny improved the safety and efficacy of existing operations, such as the vaginal hysterectomy, which involves the surgical removal of some or all of a woman’s reproductive structures. He contributed to other surgeries involving the esophagus, kidneys, and intestines. 2020-10-06 6 Oct 2020 - 10:37:45pm
Horatio Robinson Storer (1830–1922) Richa Venkatraman Horatio Robinson Storer was a surgeon and anti-abortion activist in the 1800s who worked in the field of women’s reproductive health and led the Physicians’ Crusade Against Abortion in the US. Historians credit Storer as being one of the first physicians to distinguish gynecology, the study of diseases affecting women and their reproductive health, as a separate subject from obstetrics, the study of pregnancy and childbirth. 2020-09-21 21 Sep 2020 - 8:25:06pm
HeLa Cell Line Rohini Nott The HeLa cell line was the first immortal human cell line that George Otto Gey, Margaret Gey, and Mary Kucibek first isolated from Henrietta Lacks and developed at The Johns Hopkins Hospital in Baltimore, Maryland, in 1951. An immortal human cell line is a cluster of cells that continuously multiply on their own outside of the human from which they originated. Scientists use immortal human cell lines in their research to investigate how cells function in humans. 2020-09-18 18 Sep 2020 - 7:29:36pm
Ian Hector Frazer (1953– ) Alexis Darby Ian Hector Frazer studied the human immune system and vaccines in Brisbane, Australia, and helped invent and patent the scientific process and technology behind what later became the human papillomavirus, or HPV, vaccinations. According to the Centers for Disease Control and Prevention of the US, or CDC, HPV is the most common sexually transmitted infection, and can lead to genital warts, as well as cervical, head, mouth, and neck cancers. 2020-09-02 2 Sep 2020 - 5:24:46pm
Emma Wolverton (1889–1978) James Walter Dennert Emma Wolverton, also known as Deborah Kallikak, lived her entire life in an institution in New Jersey after psychologist Henry Goddard classified her as feeble-minded. He also wrote a book about Wolverton and her family that psychiatrists previously used to show that intellectual disability is hereditary. At the time, researchers in the psychology field, including Goddard, were working to understand differences in people’s intellectual abilities. They used the term feeble-minded to refer to those they described as having lower intellectual functioning. 2020-08-25 27 Aug 2020 - 12:03:00am
Priscilla White (1900–1989) Blaise Castagnetti Priscilla White studied the treatment of diabetes in mothers, pregnant women, and children during the twentieth century in the US. White began working with children with Type 1 diabetes in 1924 at Elliott Proctor Joslin’s practice in Boston, Massachusetts. Type 1 diabetes is an incurable disease where the pancreas produces little to no insulin. Insulin is a hormone that allows the body to use sugar from food for energy and store sugars for future use. Joslin and White co-authored many publications on children 2018-02-26 29 Jul 2020 - 10:40:32pm
Albert William Liley (1929–1983) Kathleen O'Connor 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. 2011-05-11 7 Jul 2020 - 7:31:09pm
Ina May Gaskin (1940– ) Megan O’Reilly Ina May Gaskin is a certified professional midwife, or CPM, in the US during the late twentieth and early twenty-first centuries. She worked at the Farm Midwifery Center in Summertown, Tennessee, a center well known for its low rates of intervention, which contributed to low rates of maternal and fetal mortality. One technique Gaskin used when assisting women with delivery helped resolve a complication called shoulder dystocia, which is when a part of the infant’s body is delivered, but the rest of the body is stuck in the birth canal. 2020-06-16 17 Jun 2020 - 1:59:13am
Stephen Jay Gould (1941-2002) M. Elizabeth Barnes Stephen Jay Gould studied snail fossils and worked at Harvard University in Cambridge, Massachusetts during the latter half of the twentieth century. He contributed to philosophical, historical, and scientific ideas in paleontology, evolutionary theory, and developmental biology. Gould, with Niles Eldredge, proposed the theory of punctuated equilibrium, a view of evolution by which species undergo long periods of stasis followed by rapid changes over relatively short periods instead of continually accumulating slow changes over millions of years. 2014-02-18 17 Sep 2019 - 7:15:06pm
Thomas Raphael Verny (1936– ) Carrie Keller During the twentieth century, Thomas Raphael Verny studied the way that environment affects a developing fetus’s character and psychological development. Verny studied the concept of memory before birth and covered both the prenatal and perinatal periods, meaning the time the fetus is in the womb and the weeks immediately before or after birth, respectively. During those times, Verny claimed that patterns of maternal attitudes and experiences, such as affection and stress-related emotions, impact the development of the child. 2019-07-31 12 Aug 2019 - 10:43:14pm
Karl Freiherr von Rokitansky (1804–1878) Emily Santora During the nineteenth century, Karl Freiherr von Rokitansky conducted research on the causes of disease by performing approximately 30,000 autopsies, a practice that many people opposed at the time. Rokitansky performed his research in pathology, or the study of disease, and morbid anatomy, or the study of dead bodies, in Vienna, then part of the Austrian Empire and later part of Austria. 2019-08-12 12 Aug 2019 - 10:42:41pm
Otto Rank (1884–1939) Carrie Keller Otto Rank studied how birth impacts individuals’ psychology and creates anxiety throughout their lives in Europe and the US during the nineteenth century. In his book The Trauma of Birth, Rank stated that birth was extremely traumatic and that one spent his or her whole life trying to recover from the experience of being born and harshly separated from the peaceful womb. He argued that the trauma experienced at birth is the source of all human suffering and the key to understanding anxiety later in life. 2019-08-12 12 Aug 2019 - 7:59:59pm
Gail Roberta Martin (1944– ) Lance Villarreal In the twentieth and early twenty-first centuries, Gail Roberta Martin specialized in biochemistry and embryology, more specifically cellular communication and the development of organs. In 1981, she named any cell taken from inside a human embryo at the blastocyst stage an “embryonic stem cell”. During development, an embryo goes through the blastocyst stage just before it implants in the uterus. Embryonic stem cells are useful for experiments because they are self-renewing and able to develop into almost any cell type in the body. 2019-07-31 31 Jul 2019 - 11:14:51pm
William Thomas Astbury (1898–1961) Victoria Hernandez William Thomas Astbury studied the structures of fibrous materials, including fabrics, proteins, and deoxyribonucleic acid, or DNA, in England during the twentieth century. Astbury employed X-ray crystallography, a technique in which scientists use X-rays to learn about the molecular structures of materials. Astbury worked at a time when scientists had not yet identified DNA’s structure or function in genes, the genetic components responsible for how organisms develop and reproduce. He was one of the first scientists to use X-ray crystallography to study the structure of DNA. 2019-06-03 5 Jun 2019 - 1:14:56am
Dana Louise Raphael (1926–2016) Alexis Darby Dana Louise Raphael was an anthropologist and breastfeeding advocate in the US during the twentieth century. After she was unable to breastfeed her own infant, Raphael began to research why breastfeeding was more common in other cultures than in the US. As part of that research, Raphael cofounded the Human Lactation Center, where she studied the breastfeeding habits of mothers around the world. Through that research, she coordinated with formula manufacturers to educate women on the benefits of breastfeeding and formula supplementation to reduce infant mortality in developing nations. 2018-05-16 7 Mar 2021 - 8:37:40pm
Alfred Day Hershey (1908–1997) Victoria Hernandez During the twentieth century in the United States, Alfred Day Hershey studied phages, or viruses that infect bacteria, and experimentally verified that genes were made of deoxyribonucleic acid, or DNA. Genes are molecular, heritable instructions for how an organism develops. When Hershey started to study phages, scientists did not know if phages contained genes, or whether genes were made of DNA or protein. In 1952, Hershey and his research assistant, Martha Chase, conducted phage experiments that convinced scientists that genes were made of DNA. 2019-04-29 30 Apr 2019 - 10:18:40am
Mary Warnock (1924–2019 ) Jonathon J. LaTourelle Baroness Mary Warnock of Weeke, a philosopher and crossbench member and Life Peer of the United Kingdom's House of Lords, participated in several national British committees of inquiry that dealt with ethical and policy issues surrounding animal experimentation, pollution, genetics, and euthanasia to educational policies for children with special needs. One of these was the Committee of Inquiry into Human Fertilization and Embryology, of which Warnock was the chair. 2014-09-29 3 Apr 2019 - 3:41:21am
Jesse Bennett (1769–1842) Claire Grayson Jesse Bennett, sometimes spelled Bennet, practiced medicine in the US during the late eighteenth century and performed one of the first successful cesarean operations, later called cesarean sections, in 1794. Following complications during his wife’s childbirth, Bennett made an incision through her lower abdomen and uterus to deliver their infant. Bennett’s biographers report that his operation was the first cesarean section where both the pregnant woman and the infant survived. 2018-12-10 30 Jan 2019 - 2:24:04am
Matthew Howard Kaufman (1942–2013) Lance Villarreal Matthew Kaufman was a professor of anatomy at the University of Edinburgh, in Edinburgh, UK, who specialized in mouse anatomy, development, and embryology during the late twentieth century. According to the The Herald, he was the first, alongside his colleague Martin Evans, to isolate and culture embryonic stem cells. Researchers initially called those cells Evans-Kaufman cells. In 1992, Kaufman published The Atlas of Mouse Development, a book that included photographs of mice development and mice organs over time. 2018-08-31 26 Jan 2019 - 2:56:33am
William Smellie (1697–1763) Yvette Tran William Smellie helped to incorporate scientific medicine into the process of childbirth in eighteenth century Britain. As a male physician practicing in childbirth and female reproductive health (man-midwife), Smellie developed and taught procedures to treat breech fetuses, which occur when a fetus fails to rotate its head towards the birth canal during delivery. Throughout his career, Smellie compiled a wealth of information about female anatomy in his writings. He modified medical technology such as the obstetrical forceps, an instrument used to maneuver the fetus during childbirth. 2017-05-30 25 Jan 2019 - 2:58:10am
People's Padre: An Autobiography (1954), by Emmett McLoughlin Claudia Nunez-Eddy Emmett McLoughlin wrote People's Padre: An Autobiography, based on his experiences as a Roman Catholic priest advocating for the health of people in Arizona. The Beacon Press in Boston, Massachusetts, published the autobiography in 1954. McLoughlin was a Franciscan Order Roman Catholic priest who advocated for public housing and healthcare for the poor and for minority groups in Phoenix, Arizona, during the mid twentieth century. The autobiography recounts McLoughlin's efforts in founding several community initiatives throughout Phoenix, including the St. 2016-11-08 7 Mar 2021 - 8:37:40pm
Barry Morris Goldwater (1909–1998) Claudia Nunez-Eddy Barry Morris Goldwater was a Republican Arizona Senator and US presidential candidate in the twentieth-century whose policies supported the women's reproductive rights movement. Goldwater, a businessman and Air Force reservist, transitioned into politics in the 1950s. He helped align popular support for a conservative Republican Party in the 1960s. Throughout his life, he worked to maintain personal liberty and to limit governmental intrusion into citizens' private lives. Goldwater, influenced by his wife Margaret (Peggy) Goldwater, supported women's rights to abortions. 2016-10-28 15 Jan 2019 - 2:22:24am

Goldwater was a socialite and philanthropist and was married to Barry Goldwater, US Senator from Arizona. She spent much of her life working to further the women's reproductive rights movement, which sought to expand women's legal, social, and physical access to reproductive healthcare, including contraception and abortions. 2016-10-13 15 Jan 2019 - 2:18:52am
Pearl Mao Tang (1922– ) Lakshmeeramya Malladi A licensed obstetrician and gynecologist, Pearl Tang worked to improve the health of women and children in Maricopa County, Arizona, during the twentieth and twenty-first centuries. Her work with the Maricopa County Health Department ranged from immunizations to preventing cervical cancer. Tang obtained federal grants and community support to establish various child and maternal health clinics throughout Maricopa County as chief of the Maricopa County Bureau of Maternal and Child Health. 2017-06-23 15 Jan 2019 - 2:11:24am
Franklin William Stahl (1929– ) Victoria Hernandez Franklin William Stahl studied DNA replication, bacteriophages, and genetic recombination in the US during the mid-twentieth and early twenty-first centuries. With his colleague Matthew Meselson, Stahl performed an experiment called the Meselson-Stahl experiment, which provided evidence for a process called semi-conservative DNA replication. Semi-conservative replication is a process in which each strand of a parental DNA double helix serves as a template for newly replicated daughter strands, so that one parental strand is conserved in every daughter double helix. 2017-07-20 15 Jan 2019 - 1:39:51am
