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
Rudolf Carl Virchow (1821-1902) Megan Kearl Rudolf Carl Virchow lived in nineteenth century Prussia, now Germany, and proposed that omnis cellula e cellula, which translates to each cell comes from another cell, and which became and fundamental concept for cell theory. He helped found two fields, cellular pathology and comparative pathology, and he contributed to many others. Ultimately Virchow argued that disease is caused by changes in normal cells, also known as cellular pathology. 2012-03-17 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

Charles Robert Cantor (1942- ) Alexis Abboud Charles Robert Cantor helped sequence the human genome, and he developed methods to non-invasively determine the genes in human fetuses. Cantor worked in the US during the twentieth and twenty-first centuries. His early research focused on oligonucleotides, small molecules of DNA or RNA. That research enabled the development of a technique that Cantor subsequently used to describe nucleotide sequences of DNA, a process called sequencing, in humans. Cantor was the principal scientist for the Human Genome Project, for which scientists sequenced the entirety of the human genome in 2003. 2015-06-11 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

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
Barbara McClintock (1902-1992) Federica Turriziani Colonna Barbara McClintock worked on genetics in corn (maize) plants and spent most of her life conducting research at the Cold Spring Harbor Laboratory in Laurel Hollow, New York. McClintock's research focused on reproduction and mutations in maize, and described the phenomenon of genetic crossover in chromosomes. Through her maize mutation experiments, McClintock observed transposons, or mobile elements of genes within the chromosome, which jump around the genome. McClintock received the Nobel Prize for Physiology or Medicine in 1983 for her research on chromosome transposition. 2014-07-05 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
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.

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
