Stanley Cohen (1922- ) Adam R. Navis Stanley Cohen is a biochemist who participated in the discovery of nerve growth factor (NGF) and epidermal growth factor (EGF). He shared the 1986 Nobel Prize in Physiology or Medicine with Rita Levi-Montalcini for their work on the discovery of growth factors. His work led to the discovery of many other growth factors and their roles in development. 2007-11-01 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
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
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
St. George Jackson Mivart (1827-1900) Divyash Chhetri St. George Jackson Mivart studied animals and worked in England during the nineteenth century. He also proposed a theory of organismal development that he called individuation, and he critiqued Charles Darwin's argument for evolution by natural selection. His work on prosimians, a group of primates excluding apes and monkeys, helped scientists better investigate the Primate group. 2014-04-04 4 Jul 2018 - 4:40:59am
St. Augustine (354-430) Katherine Brind'Amour St. Augustine of Hippo, born Aurelius Augustinus to a respectable family in the year 354 CE, is now considered one of the foremost theologians in the history of the Catholic Church. His writings, including his philosophy regarding life in the womb and the moral worth of embryos, influenced many other great thinkers of his time and throughout history. 2007-11-01 4 Jul 2018 - 4:40:59am
Solomon A. Berson (1918-1972) Jennifer R. Craer Solomon A. Berson helped develop the radioimmunoassay (RIA) technique in the US during the twentieth century. Berson made many scientific contributions while working with research partner Rosalyn Yalow at the Bronx Veterans Administration (VA) hospital, in New York City, New York. In the more than twenty years that Berson and Yalow collaborated, they refined the procedures for tracing diagnostic biological compounds using isotope labels. 2013-11-01 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
Sir Frederick Gowland Hopkins 1925?-1945? 4 Jul 2018 - 4:41:00am
Sir D'Arcy Wentworth Thompson (1860-1948) Mark A. Ulett Known by many for his wide-reaching interests and keen thinking, D'Arcy Wentworth Thompson was one of Britain's leading scientific academics in the first few decades of the twentieth century. A prodigious author, Thompson published some 300 papers, books, and articles in the biological sciences, classics, oceanography, and mathematics. He was a famous lecturer and conversationalist-a true "scholar-naturalist," as his daughter wrote in her biography of her father. 2010-06-29 4 Jul 2018 - 4:40:59am
Simone Mary Campbell (1945–) Claire Cleveland Simone Campbell is a Roman Catholic sister, attorney, and poet who advocated for social justice, especially equal access to healthcare in the US in the twentieth and twenty-first centuries. Campbell worked as a lawyer and served the working poor in California. As of 2018, she works for NETWORK, a lobbying group in Washington DC that focuses on broadening access to healthcare by lowering costs. 2018-06-25 4 Jul 2018 - 4:40:59am
Simon Edward Fisher (1970-) Kat Fowler Simon Edward Fisher studied the genes that control speech and language in England and the Netherlands in the late twentieth and early twenty-first centuries. In 2001, Fisher co-discovered the FOXP2 gene with Cecilia Lai, a gene related to language acquisition in humans and vocalization in other mammals. When damaged, the human version of the gene leads to language disorders that disrupt language and speech skills. Fisher's discovery validated the hypothesis that genes influence language, resulting in further investigations of language disorders and their heritability. 2017-04-27 4 Jul 2018 - 4:40:59am
Sidney Q. Cohlan (1915-1999) Bianca Zietal, Chanapa Tantibanchachai Sidney Q. Cohlan studied birth defects in the US during the twentieth century. Cohlan helped to discover that if a pregnant woman ate too much vitamin A her fetus faced a higher than normal risk of teratogenic effects, such as cleft palate. A teratogen is a substance that causes malformation of a developing organism. Cohlan also identified the teratogenic effects of several other substances including a lack of normal magnesium and prenatal exposure to the antibiotic tetracycline. 2017-06-18 4 Jul 2018 - 4:40:59am

Shinya Yamanaka (1962- ) Samuel Philbrick Shinya Yamanaka gained international prominence after publishing articles detailing the successful generation of induced pluripotent stem (iPS) cells, first in mice, then in humans. Yamanaka induced somatic cells to act like human embryonic stem cells (hESCs), allowing researchers to experiment with non-embryonic stem cells with a similar capacity as hESCs. The research involving iPS cells therefore offered new potential for research and application in medical treatment, without many of the ethical objections that hESC research entailed. 2011-04-07 4 Jul 2018 - 4:40:59am

Sheldon Clark Reed (1910-2003) Cassidy Possehl 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. 2017-06-10 4 Jul 2018 - 4:40:59am

Santiago Felipe Ramon y Cajal (1852-1934) Sarah Taddeo Santiago Felipe Ramon y Cajal investigated brains in the nineteenth and twentieth centuries in Spain. He identified and individuated many components of the brain, including the neuron and the axon. He used chick embryos instead of adult animals, then customary in brain research, to study the development and physiology of the cerebellum, spinal cord, and retina. Ramon y Cajal received the Nobel Prize in Physiology and Medicine in 1906, along with Camillo Golgi, for his work on the structure of the nervous system. 2014-06-05 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
