Pope Paul VI (1897-1978) Katherine Brind'Amour, Benjamin Garcia Pope Paul VI, born Giovanni Battista Enrico Antonio Maria Montini, has been crucial to the clarification of Roman Catholic views on embryos and abortion in recent history. His 1968 encyclical "Humanae Vitae" spoke to the regulation of birth through various methods of contraception and sterilization. This encyclical, a result of Church hesitancy to initiate widespread discussion of the issue in a council of the Synod of Bishops, led to much controversy in the Church but established a firm Catholic position on the issues of birth control and family planning. 2007-11-11 4 Jul 2018 - 4:40:59am
Thomas Hunt Morgan (1866-1945) Mary E. Sunderland Although best known for his work with the fruit fly, for which he earned a Nobel Prize and the title "The Father of Genetics," Thomas Hunt Morgan's contributions to biology reach far beyond genetics.

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
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

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
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
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
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

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
Elizabeth Blackwell (1821–1910) Alexis Darby In the nineteenth century, Elizabeth Blackwell was a women’s healthcare reformer and the first woman to receive her medical degree in the United States.

Pierre Budin (1846-1907) Kelsey Rebovich Pierre Constant Budin worked in France to improve the lives of newborns and their mothers during the late nineteenth century. Budin stressed the importance of proper nutrition in infants and educated new mothers on breastfeeding and infant care. Budin established infant care facilities and created a nutritional check-up system for infants. Budin helped design early artificial nipples, breast pumps, and incubators for premature newborns. He also began the practice of consulting with new mothers after they gave birth, redefining the roles of obstetricians. 2017-02-11 4 Jul 2018 - 4:40:59am
Edwin Stephen Goodrich (1868-1946) Joe Brinkman Edwin Stephen Goodrich studied the structures of animals in England during the nineteenth and twentieth centuries. Goodrich studied how animals develop to identify their parts and to establish the evolutionary relationships between different species. Goodrich established that body structures can shift their positions relative to an organism's body during evolution, and he hypothesized that body structures can share ancestry (homology) between organisms of different species, even without identical body placement. 2014-12-30 4 Jul 2018 - 4:40:59am
