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

Ian Donald (1910–1987) Nicole Erjavic Ian Donald was an obstetrician who developed the technology and therapy of ultrasound diagnostics during the twentieth century in Europe. Ultrasound is a medical diagnostic technique that uses sound waves to produce images of the inside of the body. During the early 1900s, physicians had no way to see inside a woman’s uterus during pregnancy. Donald developed the first method of scanning human internal anatomy in real time, which enabled doctors to diagnose potentially fatal tumors and cysts. 2018-01-30 4 Jul 2018 - 4:40:59am
Robert William Briggs (1911-1983) Adam R. Navis Robert William Briggs was a prolific developmental biologist. However, he is most identified with the first successful cloning of a frog by nuclear transplantation. His later studies focused on the problem of how genes influence development. 2007-11-08 4 Jul 2018 - 4:40:59am
Betty Friedan (1921–2006) Sepehr Abdi-Moradi Betty Friedan advocated for the advancement of women's rights in the twentieth century in the United States. In 1963, Friedan wrote The Feminine Mystique, which historians consider a major contribution to the feminist movement. Friedan also helped establish two organizations that advocated for women's right, the National Organization for Women (NOW) in 1963 and, in 1969 the National Association for the Repeal of Abortion Laws (NAARL). Friedan argued for legalizing access to abortion and contraception, and her advocacy helped advance women's reproductive rights. 2017-06-15 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

Percivall Pott (1714-1788) Carolina Abboud Percivall Pott was a physician in England during the eighteenth century who identified soot as the cause of chimney sweeps' scrotal cancer, later called testicular cancer. In the 1770s, Pott observed that scrotal cancer commonly afflicted chimney sweeps, the young boys sent up into chimneys to clean away the soot left over from fires, and he hypothesized that the soot inside chimneys might cause that type of cancer. Pott was one of the first doctors to identify some environmental factor as causing cancer. 2017-05-31 4 Jul 2018 - 4:40:59am
Edgar Allen (1892–1943) Brendan Van Iten Edgar Allen identified and outlined the role of female sex hormones and discovered estrogen in the early 1900s in the US. In 1923, Allen, through his research with mice, isolated the primary ovarian hormone, later renamed estrogen, from ovarian follicles and tested its effect through injections in the uterine tissues of mice. Allen’s work on estrogen, enabled researchers to further study hormones and the endocrine system. 2017-07-23 4 Jul 2018 - 4:40:59am
Julia Bell (1879-1979) Jesse King Julia Bell worked in twentieth-century Britain, discovered Fragile X Syndrome, and helped find heritable elements of other developmental and genetic disorders. Bell also wrote much of the five volume Treasury of Human Inheritance, a collection about genetics and genetic disorders. Bell researched until late in life, authoring an original research article on the effects of the rubella virus of fetal development (Congenital Rubella Syndrome) at the age of 80. 2012-12-27 4 Jul 2018 - 4:40:59am

Healy conducted research on the different manifestations of heart attacks in women compared to men. At the time, many physicians underdiagnosed and mistreated coronary heart disease in women. Healy's research illustrated how coronary heart disease affected women. 2017-11-08 4 Jul 2018 - 4:40:59am
Florence Rena Sabin (1871-1953) Kimberly A. Buettner Florence Rena Sabin had successful careers as both a researcher and public health reformer. When Johns Hopkins University Medical School opened, accepting women and men on the same basis, Sabin was one of the first to enter. After the successful completion of her MD degree, Sabin went on to become the first female faculty member and later full-time professor at Johns Hopkins. 2007-11-01 4 Jul 2018 - 4:40:59am
Ignacio Vives Ponseti (1914-2009) Katherine Gandee Ignacio Vives Ponseti developed a noninvasive method for treating congenital club foot in the US during the late 1940s. Congenital club foot is a birth deformity in which one or both of an infant's feet are rotated inward beneath the ankle, making normal movement rigid and painful. Ponseti developed a treatment method, later called the Ponseti method, that consisted of a series of manipulations and castings of the club foot performed in the first few months of life. 2017-03-09 4 Jul 2018 - 4:40:59am
Elinor Catherine Hamlin (1924- ) Patsy Ciardullo Elinor Catherine Hamlin founded and helped fund centers in Ethiopia to treat women affected by fistulas from obstetric complications. Obstetric fistulas develop in women who experience prolonged labor, as the pressure placed on the pelvis by the fetus during labor causes a hole, or fistula, to form between the vagina and the bladder (vesicovaginal fistula) or between the vagina and the rectum (rectovaginal fistula). Both of those conditions result in urinary or fecal incontinence, which often impacts womenÍs social status within their communities. 2015-03-19 4 Jul 2018 - 4:40:59am

Pope Sixtus V (1520-1590) Katherine Brind'Amour Known for dropping a long-held distinction in the Catholic Church between the animated and unanimated fetus, Felice Peretti was born in Grottamare, Italy, in 1521, son of a Dalmatian gardener. In his early years, Peretti worked as a swineherd, but soon became involved in the local Minorite convent in Montalto, where he served as a novice at the age of twelve. He went on to study in Montalto, Ferrara, and Bologna, continuing his devotion to religious life, and in 1547 Peretti was ordained as priest in the city of Siena. 2007-11-11 4 Jul 2018 - 4:40:59am
Christian Heinrich Pander (1794-1865) Stephen C. Ruffenach Christian Heinrich Pander, often remembered as the father of embryology, also explored the fields of osteology, zoology, geology, and anatomy. He was born in Riga, Latvia, on 24 July 1794. Pander, with an eclectic history of research, is best remembered for his discovery and explanation of the structure of the chick blastoderm, a term he coined. In doing so, Pander was able to achieve the goal set forth by his teacher, Ignaz Döllinger, to reinvigorate the study of the chick embryo as a means of further exploring the science of embryology as a whole. 2009-07-22 4 Jul 2018 - 4:40:59am
Robert Guthrie (1916–1995) Meilin Zhu Robert Guthrie developed a method to test infants for phenylketonuria (PKU) in the United States during the twentieth century. PKU is an inherited condition that causes an amino acid called phenylalanine to build to toxic levels in the blood. Untreated, PKU causes mental disabilities. Before Guthrie’s test, physicians rarely tested infants for PKU and struggled to diagnosis it. Guthrie’s test enabled newborns to be quickly and cheaply screened at birth and then treated for PKU if necessary, preventing irreversible neurological damage. 2017-02-23 4 Jul 2018 - 4:40:59am

Charles Otis Whitman (1842-1910) D. Brian Schuermann Charles Otis Whitman was an extremely curious and driven researcher who was not content to limit himself to one field of expertise. Among the fields of study to which he made significant contributions were: embryology; morphology, or the form of living organisms and the relationships between their structures; natural history; and behavior. 2009-01-21 4 Jul 2018 - 4:40:59am
Victor Ambros (1953-) Catherine May, Justin M. Wolter Victor Ambros is a professor of molecular medicine at the University of Massachusetts Medical School, and he discovered the first microRNA (miRNA) in 1993. Ambros researched the genetic control of developmental timing in the nematode worm Caenorhabditis elegans and he helped describe gene function and regulation during the worm’s development and embryogenesis. His discovery of miRNA marked the beginning of research into a form of genetic regulation found throughout diverse life forms from plants to humans. Ambros is a central figure in the miRNA and C. 2012-05-13 4 Jul 2018 - 4:40:59am
Virginia Apgar (1909-1974) Carolina J. Abboud Virginia Apgar worked as an obstetrical anesthesiologist, administering drugs that reduce women’s pain during childbirth, in the US in the mid-twentieth century. In 1953, Apgar created a scoring system using five easily assessable measurements, including heart rate and breathing rate, to evaluate whether or not infants would benefit from medical attention immediately after birth. Apgar’s system showed that infants who were previously set aside as too sick to survive, despite low Apgar scores, could recover with immediate medical attention. 2017-02-16 4 Jul 2018 - 4:40:59am
