Caspar Friedrich Wolff (1734-1794) Stephen Ruffenach Caspar Friedrich Wolff is most famous for his 1759 doctoral dissertation, Theoria Generationis, in which he described embryonic development in both plants and animals as a process involving layers of cells, thereby refuting the accepted theory of preformation: the idea that organisms develop as a result of the unfolding of form that is somehow present from the outset, as in a homunculus. This work generated a great deal of controversy and discussion at the time of its publication but was an integral move in the reemergence and acceptance of the theory of epigenesis. 2009-07-07 4 Jul 2018 - 4:40:59am

Rosalyn Sussman Yalow (1921-2011) Jennifer R. Craer Rosalyn Sussman Yalow co-developed the radioimmunoassay (RIA), a method used to measure minute biological compounds that cause immune systems to produce antibodies. Yalow and research partner Solomon A. Berson developed the RIA in the early 1950s at the Bronx Veterans Administration (VA) Hospital, in New York City, New York. Yalow and Berson's methods expanded scientific research, particularly in the medical field, and contributed to medical diagnostics. For this achievement, Yalow received the Nobel Prize in Physiology or Medicine in 1977. 2013-09-10 4 Jul 2018 - 4:40:59am
William Bateson (1861-1926) Samantha Hauserman At the turn of the twentieth century, William Bateson studied organismal variation and heredity of traits within the framework of evolutionary theory in England. Bateson applied Gregor Mendel's work to Charles Darwin's theory of evolution and coined the term genetics for a new biological discipline. By studying variation and advocating Mendelian genetics, Bateson furthered the field of genetics, encouraged the use of experimental methodology to study heredity, and contributed to later theories of genetic inheritance. 2014-01-28 4 Jul 2018 - 4:40:59am

Margaret Ann Bulkley (James Barry) (1789−1865) Sarah Foster Margaret Ann Bulkley, under the male pseudonym James Barry, was one of the first female obstetricians in early nineteenth century British Empire. She was the first person to perform a cesarean section in South Africa. Cesarean section is a procedure in which a doctor cuts into the uterus of a pregnant woman to retrieve the fetus during complicated births. Bulkley hid her gender and lived life as the male Barry to practice medicine, an opportunity not allowed to women at the time. 2017-02-11 4 Jul 2018 - 4:40:59am
Walter Jakob Gehring (1939-2014) Joe Brinkman Walter Jakob Gehring discovered the homeobox, a DNA segment found in a specific cluster of genes that determine the body plan of animals, plants, and fungi. Gehring identified the homeobox in 1983, with the help of colleagues while isolating the Antennapedia (Antp) gene in fruit flies (Drosophila) at the University of Basel in Basel, Switzerland. Hox genes, a family of genes that have the homeobox, determine the head-to-tail (anterior-posterior) body axis of both vertebrates and invertebrates. 2014-12-22 4 Jul 2018 - 4:40:59am

DuPont Marie Charlotte Carmichael Stopes was born in Edinburgh, Scotland, on 15 October 1880 to Charlotte Carmichael Stopes, a suffragist, and Henry Stopes, an archaeologist and anthropologist. A paleobotanist best known for her social activism in the area of sexuality, Stopes was a pioneer in the fight to gain sexual equality for women. Her activism took many forms including writing books and pamphlets, giving public appearances, serving on panels, and, most famously, co-founding the first birth control clinic in the United Kingdom. 2008-07-10 4 Jul 2018 - 4:40:59am
Oswald Theodore Avery (1877-1955) Samantha Hauserman Oswald Theodore Avery studied strains of pneumococcus of the genus Streptococcus in the US in the first half of the twentieth century. This bacterium causes pneumonia, a common cause of death at the turn of the twentieth century. In a 1944 paper, Avery demonstrated with colleagues Colin Munro MacLeod and Maclyn McCarty that deoxyribonucleic acid, or DNA, instead of protein, formed the material of heritable transformation in bacteria. Avery helped untangle some of the relationships between genes and developmental processes. 2013-12-12 4 Jul 2018 - 4:40:59am
Katharina Dorothea Dalton (1916–2004) Bianca Zietal Katharina Dorothea Dalton was a physician in England in the twentieth century who defined premenstrual syndrome (PMS) as a cluster of symptoms suspected to begin one to two weeks before menstruation and disappear upon the onset of a new menstrual cycle. Prior to Dalton, there was little research on pre-menstrual issues and those that existed linked the problem to excessive water retention or estrogen. Dalton hypothesized that PMS resulted from a deficiency in the hormone progesterone and advocated for hormone replacement therapy to lessen the symptoms of the syndrome. 2017-05-24 4 Jul 2018 - 4:40:59am
Adolf Ziegler Karen Wellner The scientific field of embryology experienced great growth in scope and direction in Germany from approximately 1850 to 1920. During this time, Adolf Ziegler and his son Friedrich crafted hundreds of wax embryo models, representing a shift in how embryos were viewed and used. Their final products, whether human or trout embryos, showcased the now lost collaboration between wax modeling artists and embryologists. 2009-06-10 4 Jul 2018 - 4:40:59am

Leo Kanner (1894-1981) Sean Cohmer Leo Kanner studied and described early infantile autism in humans in the US during the twentieth century. Though Eugen Bleuler first coined the term autism in 1910 as a symptom of schizophrenia, Kanner helped define autism as a disease concept separate from schizophrenia. He helped found an early child psychiatry department in 1930 at the Johns Hopkins University Hospital in Baltimore, Maryland. 2014-04-30 4 Jul 2018 - 4:40:59am
Albrecht von Haller (1708-1777) Cera R. Lawrence Victor Albrecht von Haller was an 18th century scientist who did extensive work in the life sciences, including anatomy and physiology, botany, and developmental biology. His embryological work consisted of experiments in understanding the process of generation, and led him to adopt the model of preformationism called ovism (the idea that the new individual exists within the maternal egg prior to conception). Haller was born in Bern, Switzerland, on 16 October, 1708. His mother was Anna Maria Engel, and his father was Niklaus Emanuel Haller. 2008-09-22 4 Jul 2018 - 4:40:59am
Viktor Hamburger (1900-2001) Adam R. Navis Viktor Hamburger was an embryologist who focused on neural development. His scientific career stretched from the early 1920s as a student of Hans Spemann to the late 1980s at Washington University resolving the role of nerve growth factor in the life of neurons. Hamburger is noted for his systematic approach to science and a strict attention to detail. Throughout his life he maintained an interest in nature and the arts, believing both were important to his scientific work. 2007-11-08 4 Jul 2018 - 4:40:59am

Etienne Geoffroy Saint-Hilaire (1772-1844) Valerie Racine Etienne Geoffroy Saint-Hilaire, commonly known as Geoffroy, studied animals, their anatomy and their embryos, and teratogens at the National Museum of Natural History in Paris, France in the eighteenth and nineteenth centuries. Geoffroy also helped develop several specialized fields in the life sciences, including experimental embryology. In his efforts to experimentally demonstrate the theory of recapitulation, Geoffroy developed techniques to intervene in the growth of embryos to see whether they would develop into different kinds of organisms. 2013-08-05 4 Jul 2018 - 4:40:59am
St. Thomas Aquinas (c. 1225-1274) Katherine Brind'Amour Widely known as a key contributor to the Roman Catholic Church's body of doctrine, St. Thomas Aquinas also published an opinion on the moral status of embryos and fetuses that seems contradictory to the Catholic Church's current standpoint on the matter. Born in Naples, Italy, around 1225 (scholars debate the exact year of many of his life events) to wealthy nobility, Thomas Aquinas quickly proved himself a pious and astute scholar with an insatiable desire for logic and understanding. 2007-11-11 4 Jul 2018 - 4:40:59am
