Edward Drinker Cope (1840-1897) Karla T. Moeller Edward Drinker Cope studied fossils and anatomy in the US in the late nineteenth century. Based on his observations of skeletal morphology, Cope developed a novel mechanism to explain the law of parallelism, the idea that developing organisms successively pass through stages resembling their ancestors. Others had proposed the addition of new body forms at the end of an individual organism's developed as a mechanism through which new species arose, but those proposals relied on changes in the lengths of gestation or incubation. 2012-01-01 4 Jul 2018 - 4:40:59am
Alfred Henry Sturtevant (1891–1970) Kevin Gleason Alfred Henry Sturtevant studied heredity in fruit flies in the US throughout the twentieth century. From 1910 to 1928, Sturtevant worked in Thomas Hunt Morgan’s research lab in New York City, New York. Sturtevant, Morgan, and other researchers established that chromosomes play a role in the inheritance of traits. In 1913, as an undergraduate, Sturtevant created one of the earliest genetic maps of a fruit fly chromosome, which showed the relative positions of genes along the chromosome. 2017-05-20 4 Jul 2018 - 4:40:59am

Carl Richard Moore (1892-1955) Mary Drago Carl Richard Moore was a professor and researcher at the University of Chicago in Chicago, Illinois who studied sex hormones in animals from 1916 until his death in 1955. Moore focused on the role of hormones on sex differentiation in offspring, the optimal conditions for sperm production, and the effects of vasectomy or testicular implants on male sex hormone production. Moore's experiments to create hermaphrodites in the laboratory contributed to the theory of a feedback loop between the pituitary and fetal gonadal hormones to control sex differentiation. 2014-02-18 4 Jul 2018 - 4:40:59am

Samuel Randall Detwiler (1890-1957) Adam R. Navis Samuel Randall Detwiler was an embryologist who studied neural development in embryos and vertebrate retinas. He discovered evidence for the relationship between somites and spinal ganglia, that transplanted limbs can be controlled by foreign ganglia, and the plasticity of ganglia in response to limb transplantations. He also extensively studied vertebrate retinas during and after embryonic development. 2007-11-01 4 Jul 2018 - 4:40:59am
Barbara Seaman (1935–2008) Rainey Horwitz Barbara Seaman was a writer, investigator, and advocate for female healthcare rights during the twentieth century in the United States. Seaman’s work addressed the gendered prejudice she observed in the US healthcare system and argued that women of the 1960s lacked the proper tools to make informed decisions about pregnancy care, breastfeeding, childbirth, and contraception. Seaman wrote the book The Doctor’s Case Against the Pill in 1969 to expose the dangers in prescribing and consuming high doses of estrogen in the form of birth control. 2018-05-25 4 Jul 2018 - 4:40:59am
Harald zur Hausen (1936–) Grace Kim Harald zur Hausen studied viruses and discovered that certain strains of the human papilloma virus (HPV), a sexually transmitted disease, can cause cervical cancer, in Europe during the twentieth and twenty-first centuries. Zur Hausen spent his research career identifying the viruses that cause diseases, particularly cancer-causing viruses (oncoviruses). He primarily focused on HPV and cervical cancer. Zur Hausen hypothesized that HPV was cancerous and discovered that two strains, HPV 16 and 18, caused cervical cancer. 2017-07-24 4 Jul 2018 - 4:40:59am
Stafford Leak Warren (1896–1981) Meilin Zhu Stafford Leak Warren studied nuclear medicine in the United States during the twentieth century. He used radiation to make images of the body for diagnosis or treatment and developed the mammogram, a breast imaging technique that uses low-energy X-rays to produce an image of breasts. Mammograms allow doctors to diagnose breast cancer in its early and most treatable stages. 2017-08-30 4 Jul 2018 - 4:40:59am

Wilhelm Ludvig Johannsen (1857-1927) B. R. Erick Peirson Wilhelm Ludvig Johannsen studied plants and helped found the field of genetics, contributing methods and concepts to the study of heredity around the turn of the twentieth century in Denmark. His experiments on heredity and variation in plants influenced the methods and techniques of geneticists, and his distinction between the genotype of an organism-its hereditary disposition-and its phenotype-its observable characteristics-remains at the core of contemporary biology. Johannsen criticized biological explanations that relied on concepts such as vitalism and teleology. 2012-11-16 4 Jul 2018 - 4:40:59am
Sir Graham Collingwood Liggins (1926-2010) Kathleen O'Connor Sir Graham Collingwood Liggins devoted much of his professional life to obstetric research. Liggins demonstrated that hormones created by the fetus helped initiate labor, rather than hormones originating solely from the mother. Liggins also discovered that cortisol given to pregnant mothers helped delay premature labor, and that it increased the likelihood that premature infants would breathe normally after birth. Prior to cortisol treatment, premature infants often died of respiratory distress syndrome characterized by the inability to inflate immature lungs. 2012-02-16 4 Jul 2018 - 4:40:59am

Jacques Loeb (1859-1924) Steve Elliott Jacques Loeb experimented on embryos in Europe and the United States at the end of the nineteenth and beginning of the twentieth centuries. Among the first to study embryos through experimentation, Loeb helped found the new field of experimental embryology. Notably, Loeb showed scientists how to create artificial parthenogenesis, thus refuting the idea that spermatozoa alone were necessary to develop eggs into embryos and confirming the idea that the chemical constitution of embryos environment affected their development. 2009-06-10 4 Jul 2018 - 4:40:59am
Stanley Alan Plotkin (1932– ) Christian H. Ross Stanley Alan Plotkin developed vaccines in the United States during the mid to late twentieth century. Plotkin began his research career at the Wistar Institute in Philadelphia, Pennsylvania, where he studied the rubella virus. In pregnant women, the rubella virus caused congenital rubella syndrome in the fetus, which led to various malformations and birth defects. Using WI-38 cells, a line of cells that originated from tissues of aborted fetuses, Plotkin successfully created RA27/3, a weakened strain of the rubella virus, which he then used to develop a rubella vaccine. 2017-04-13 4 Jul 2018 - 4:40:59am

James William Kitching (1922-2003) Paige Madison James William Kitching collected and studied fossils of dinosaurs and early humans in the twentieth century. He worked at the Bernard Price Institute for Paleontological Research in South Africa. During the fifty-three years he worked at the institute, Kitching spent eighteen of those in the field uncovering fossils. Kitching recovered fossils of early human ancestors, later called Australopithecines, as well as fossils of dinosaurs and ancient mammals. When he died in 2003, the Bernard Price Institute housed one of the largest fossil collections in the southern hemisphere. 2015-03-31 4 Jul 2018 - 4:40:59am
Andreas Vesalius (1514–1564) Nicole Erjavic Andreas Vesalius, also called Andries van Wesel, studied anatomy during the sixteenth century in Europe. Throughout his career, Vesalius thoroughly dissected numerous human cadavers, and took detailed notes and drawings of his research. Compiling his research, Vesalius published an anatomy work titled De humani corporis fabrica libri septem (On the fabric of the human body in seven books). The Fabrica included illustrations of dissected men, women, and uteruses with intact fetuses. 2018-01-10 4 Jul 2018 - 4:40:59am
Theodora (Theo) Emily Colborn (1927-2014) Alexis Abboud Theodora Colborn studied how chemicals affect organisms as they develop and reproduce during the twentieth and twenty first centuries in the US. By the 1940s, researchers had reported that chemicals from agricultural and industrial processes affected how wild organisms developed, but in 1991, Colborn organized the Wingspread Conference in Racine, Wisconsin, at which a group of scientists classed these chemicals as environmentally harmful substances. Colborn and her colleagues called those chemicals endocrine disruptors, as they mimic or block the body's endocrine system. 2014-12-30 4 Jul 2018 - 4:40:59am
Lydia Estes Pinkham (1819–1883) Rainey Horwitz Lydia Estes Pinkham invented and sold Lydia Pinkham’s Vegetable Compound, a medicinal tonic used to treat menstrual discomfort and promote female reproductive health in general, in the US during the nineteenth century. Pinkham also founded Mrs. Lydia E. Pinkham Medicine Company, a business that sold natural remedies for women’s health issues. Throughout her life, Pinkham acted as an authority on female wellness, writing medical pamphlets about female anatomy and reproductive processes. 2017-05-20 4 Jul 2018 - 4:40:59am

Allan Charles Wilson (1934-1991) Dorothy Haskett Allan C. Wilson studied genes, proteins, and body structures of animals and humans in the US during the second half of the twentieth century. Wilson also studied human evolution. Although morphology and behaviors of humans (Homo sapiens) and great apes differ, Wilson found that they have biochemical and genetic similarities. Wilson and his colleagues calculated the time period of humans' and African apes' common ancestor. 2014-07-24 4 Jul 2018 - 4:40:59am
Nettie Maria Stevens (1861-1912) Kaitlin Smith Multiple theories about what determines sex were tested at the turn of the twentieth century. By experimenting on germ cells, cytologist Nettie Maria Stevens collected evidence to support the connection between heredity and the sex of offspring. Stevens was able to interpret her data to conclude that chromosomes have a role in sex determination during development. For her time, she was an emerging breed: a woman of science making the leap from the world of data collection to that of male-dominated interpretive work. 2010-06-20 4 Jul 2018 - 4:40:59am
John Spangler Nicholas (1895-1963) Ellen M. Dupont John Spangler Nicholas, an American biologist, was born on 10 March 1895 in Allegheny, Pennsylvania. He was the only child of Elizabeth Ellen Spangler, a teacher, and Samuel Trauger Nicholas, a Lutheran minister. Nicholas held myriad administrative positions throughout his life and his contributions to biology spanned several sub-disciplines, but his most notable accomplishments were in the field of embryology. 2008-07-23 4 Jul 2018 - 4:40:59am
George Nicholas Papanicolaou (1883–1962) Patsy Ciardullo George Nicholas Papanicolaou developed the Pap test in the United States during the twentieth century. The Pap test is a diagnostic procedure used to test for cervical cancer in women. Papanicolaou’s work helped improve the reproductive health of women by providing an effective means of identifying precancerous cells and improving the likelihood of early treatment and survival of cervical cancer. 2017-04-06 4 Jul 2018 - 4:40:59am

Franz Julius Keibel (1861-1929) M. Elizabeth Barnes Franz Keibel studied the embryos of humans and other animals in Europe at the turn of the twentieth century. He lived and worked in several different parts of Germany and France. Keibel drew illustrations of embryos in many stages of development. Keibel used these illustrations, which he and others in the scientific community called normal plates, to describe the development of organisms in several species of vertebrates. 2014-06-21 4 Jul 2018 - 4:40:59am
G. T. Popa 1926 4 Jul 2018 - 4:40:59am
Pope Innocent XI (1611-1689) Katherine Brind'Amour, Benjamin Garcia Pope Innocent XI, born Benedetto Odescalchi, made considerable contributions to the Roman Catholic approach to embryology by condemning several propositions on liberal moral theology in 1679, including two related to abortion and ensoulment. His rejection of these principles strengthened the Church's stance against abortion and for the idea of "hominization," meaning the presence of human qualities before birth. 2007-11-11 4 Jul 2018 - 4:40:59am
Harry Hamilton Laughlin (1880-1943) Rachel Gur-Arie Harry Hamilton Laughlin helped lead the eugenics movement in the United States during the early twentieth century. The US eugenics movement of the early twentieth century sought to reform the genetic composition of the United States population through sterilization and other restrictive reproductive measures. Laughlin worked as superintendent and assistant director of the Eugenics Research Office (ERO) at Cold Spring Harbor Laboratory in Cold Spring Harbor, New York, alongside director Charles Davenport. 2014-12-19 4 Jul 2018 - 4:40:59am
Karl Oskar Illmensee (1939–) Cheryl Lancaster Karl Oskar Illmensee studied the cloning and reproduction of fruit flies, mice, and humans in the US and Europe during the twentieth and twenty-first centuries. Illmensee used nuclear transfer techniques (cloning) to create early mouse embryos from adult mouse cells, a technique biologists used in later decades to help explain how embryonic cells function during development. In the early 1980s, Illmensee faced accusations of fraud when others were unable to replicate the results of his experiments with cloned mouse embryos. 2017-02-26 4 Jul 2018 - 4:40:59am
Albert Prescott Mathews 1924 4 Jul 2018 - 4:40:59am
Carl Gottfried Hartman (1879-1968) Giavonna A. Goodman Carl Gottfried Hartman researched the reproductive physiology of opossums and rhesus monkeys. He was the first to extensively study the embryology and physiology of reproduction in opossums when little was known about this mammal. Hartman worked in Texas where opossums, the only marsupial that lives in North America, were abundant. The female opossum delivers her fetal opossums in her pouch, where one can easily observe their development. After studying opossums for thirteen years, Hartman investigated the reproductive physiology of rhesus monkeys, also known as macaques. 2011-11-01 4 Jul 2018 - 4:40:59am
Bernard Nathanson (1926-2011) Mark Zhang Bernard Nathanson was an obstetrician and gynecologist in New York City, New York, who argued for, and later against, women's rights to abortion. Between 1970 and 1979, Nathanson oversaw at least 75,000 abortions, 5,000 of which he performed himself, earning him the nickname of abortion king. However, his views regarding abortion shifted in 1973, after he watched an abortion using ultrasound imaging technology. Afterwards, Nathanson began to oppose women's rights to abortion, and he published the anti-abortion book Aborting America and produced the film Silent Scream. 2013-04-22 4 Jul 2018 - 4:40:59am
Frederik Ruysch (1638-1731) Britta Martinez Frederik Ruysch made anatomical drawings and collected and preserved human specimens, many of which were infants and fetuses, in the Netherlands during the seventeenth and eighteenth centuries. Ruysch had many interests, including anatomy, botany, and medicine, and he discovered structures of the lymphatic system and of the eye. His collection of preserved human specimens were used as educational tools for his students and for other physicians, and they were displayed in a museum of his own making that was open to the public. 2013-04-08 4 Jul 2018 - 4:40:59am
Truman William Brophy (1848–1928) Jillian Renee Kersten Truman William Brophy developed a cleft palate surgical repair, later called the Brophy Operation, in the late nineteenth century US. The procedure improved facial aesthetics and speech in cleft palate patients. A cleft palate occurs during development when the palatal bones in the roof of the mouth don't completely fuse, leaving an opening, or cleft, in the upper lip and mouth. Brophy's cleft repair used compression inside and outside of the mouth to push the palatal bones into normal alignment shortly after birth. 2017-02-11 4 Jul 2018 - 4:40:59am
