David Starr Jordan (1851-1931) Jill Briggs David Starr Jordan studied fish and promoted eugenics in the US during the late nineteenth and early twentieth centuries. In his work, he embraced Charles Darwin s theory of evolution and described the importance of embryology in tracing phylogenic relationships. In 1891, he became the president of Stanford University in Stanford, California. Jordan condemned war and promoted conservationist causes for the California wilderness, and he advocated for the eugenic sterilization of thousands of Americans. 2013-06-26 4 Jul 2018 - 4:40:59am
Priscilla White (1900–1989) Blaise Castagnetti Priscilla White studied the treatment of diabetes in mothers, pregnant women, and children during the twentieth century in the US. White began working with children with Type 1 diabetes in 1924 at Elliott Proctor Joslin’s practice in Boston, Massachusetts. Type 1 diabetes is an incurable disease where the pancreas produces little to no insulin. Insulin is a hormone that allows the body to use sugar from food for energy and store sugars for future use. Joslin and White co-authored many publications on children 2018-02-26 4 Jul 2018 - 4:40:59am
Edward Stuart Russell (1887-1954) Mark A. Ulett Edward Stuart Russell was born 23 March 1887 to Helen Cockburn Young and the Reverend John N. Russell in Port Glasgow, Scotland. Friends and co-workers alike knew Russell as a quiet and focused, though always kind and helpful person. Trained in classics and biology, Russell's interests drew him to the study of historical and philosophical issues in the biological sciences, particularly morphology and animal behavior. According to Nils Roll-Hansen, Russell was one of the most influential philosophers of biology in the second third of the twentieth century. 2010-06-29 4 Jul 2018 - 4:40:59am

David Baltimore (1938– ) Meilin Zhu David Baltimore studied viruses and the immune system in the US during the twentieth century. In 1975, Baltimore was awarded the Nobel Prize in Physiology or Medicine for discovering reverse transcriptase, the enzyme used to transfer information from RNA to DNA. The discovery of reverse transcriptase contradicted the central dogma of biology at the time, which stated that the transfer of information was unidirectional from DNA, RNA, to protein. 2017-12-27 4 Jul 2018 - 4:40:59am
Ernst Heinrich Philipp August Haeckel (1834-1919) Karen Wellner Ernst Heinrich Philipp August Haeckel was a prominent comparative anatomist and active lecturer in the late nineteenth and early twentieth centuries. He is most well known for his descriptions of phylogenetic trees, studies of radiolarians, and illustrations of vertebrate embryos to support his biogenetic law and Darwin's work with evolution. Haeckel aggressively argued that the development of an embryo repeats or recapitulates the progressive stages of lower life forms and that by studying embryonic development one could thus study the evolutionary history of life on earth. 2010-06-16 4 Jul 2018 - 4:40:59am

Karl Landsteiner (1868-1943) Corey Harbison Karl Landsteiner studied blood types in Europe and in the United States in the late nineteenth and early twentieth centuries. Landsteiner won the Nobel Prize in Physiology or Medicine in 1930 for detailing immunological reactions in the ABO blood group system. The ABO blood group system divides human blood into one of four types based on the antibodies that are present on each cell. Landsteiner's work with blood types led physicians to safely perform blood transfusions and organ transplants. 2017-02-17 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
Pope Gregory XIV (1535-1591) Angel Lopez Pope Gregory XIV, born Nicolo Sfondrati, reversed the bull of Pope Sixtus V, Effraenatum, under which an abortion at any time of gestation can be punished by excommunication. He supported the Aristotelian distinction between an "animated" and "unanimated" fetus, making abortion of an unanimated fetus punishable by lesser means. This decision contributed to the historical debates within the Roman Catholic Church on when a fetus has a soul, and when abortion was punishable by excommunication. 2010-06-22 4 Jul 2018 - 4:40:59am
Gustav Jacob Born (1851-1900) Karen Wellner Gustav Jacob Born was an experimental embryologist whose original work with amphibians served as the platform for his wax-plate method of embryo modeling, heteroblastic (different tissues) and xenoplastic (similar species) transplantation methods, environmental influences on sex ratio studies, and proposed function of the corpus luteum. He was born 22 April 1851 in Kempen, Prussia, but his family moved to the larger city of Görlitz within a year after Born's birth. His father was Marcus Born, a physician and public health officer who practiced in the town of Görlitz. 2009-07-22 4 Jul 2018 - 4:40:59am

Paul Kammerer (1880-1926) Federica Turriziani Colonna Paul Kammerer conducted experiments on amphibians and marine animals at the Vivarium, a research institute in Vienna, Austria, in the early twentieth century. Kammerer bred organisms in captivity, and he induced them to develop particular adaptations, which Kammerer claimed the organismss offspring would inherit. Kammerer argued that his results demonstrated the inheritance of acquired characteristics, or Lamarckian inheritance. The Lamarckian theory of inheritance posits that individuals transmit acquired traits to their offspring. 2014-11-25 4 Jul 2018 - 4:40:59am
Richard Woltereck (1877-1944) B. R. Erick Peirson Richard Woltereck was a German zoologist and hydrobiologist who studied aquatic animals and extended the concept of Reaktionsnorm (norm of reaction) to the study of genetics. He also provided some of the first experimental evidence for the early twentieth-century embryological theory of heredity known as cytoplasmic inheritance. Through experiments on the water flea, Daphnia, Woltereck investigated whether variation produced by environmental impacts on development could play a role in heredity and evolution. 2012-05-13 4 Jul 2018 - 4:40:59am
Rosalind Elsie Franklin (1920-1958) Lindsey O'Connell Rosalind Elsie Franklin worked with X-ray crystallography at King's College London, UK, and she helped determine the helical structure of DNA in the early 1950s. Franklin's research helped establish molecular genetics, a field that investigates how heredity works on the molecular level. The discovery of the structure of DNA also made future research possible into the molecular basis of embryonic development, genetic disorders, and gene manipulation. 2013-11-17 4 Jul 2018 - 4:40:59am

Bernard Sachs (1858-1944) Tiffany Nardi Bernard Sachs studied nervous system disorders in children in the United States during the nineteenth and twentieth centuries. In the late 1880s, Sachs described the fatal genetic neurological disorder called amaurotic family idiocy, later renamed Tay-Sachs disease. The disorder degrades motor skills as well as mental abilities in affected individuals. The expected lifespan of a child with Tay-Sachs is three to five years. In addition to working on Tay-Sachs disease, Sachs described other childhood neurological and 2017-05-31 4 Jul 2018 - 4:40:59am
Ian Wilmut (1944- ) Inbar Maayan British embryologist Sir Ian Wilmut, best known for his work in the field of animal genetic engineering and the successful cloning of sheep, was born 7 July 1944 in Hampton Lucy, England.

Studdiford to develop treatments for women who contracted infections as a result of illegal abortions performed throughout the US in unsterile environments. 2014-09-15 4 Jul 2018 - 4:40:59am
Etienne Stephane Tarnier (1828–1897) Kelsey Rebovich Etienne Stephane Tarnier was a physician who worked with premature infants in France during the nineteenth century. He worked at the Maternité Port-Royal in Paris, France, a hospital for poor pregnant women. Tarnier developed and introduced prototypes of infant incubators to the Maternité in 1881. Tarnier's incubators became standard in neonatal care, especially for premature infants, enabling doctors to save many such infants that previously would have died. 2017-07-19 4 Jul 2018 - 4:40:59am
Lynn Petra Alexander Sagan Margulis (1938-2011) Dorothy Regan Haskett Lynn Petra Alexander Sagan Margulis was an American biologist, whose work in the mid-twentieth century focused on cells living together in a mutually advantageous relationship, studied cells and mitochondria in the US during the second half of the twentieth century. She developed a theory for the origin of eukaryotic cells, that proposed two kinds of structures found in eukaryotic cells mitochondria in animals, and plastids in plantsÑwere once free-living bacteria that lived harmoniously and in close proximity to larger cells, a scenario called symbiosis. 2014-03-23 4 Jul 2018 - 4:40:59am
Pope Pius XI (1857-1939) Katherine Brind'Amour Pope Pius XI, born Ambrogio Damiano Achille Ratti, was born to the wealthy owner of a silk factory on 31 May 1857 in Desio, Italy. He was ordained to the priesthood at the age of eighteen, at which time he began a long life devoted to study, peacekeeping, and the betterment of societies around the world. Pius XI is noted here for his contribution to the Roman Catholic Church's early twentieth century approach to issues regarding contraception and abortion, which was presented in his December 1930 encyclical "Casti Connubii." 2007-11-11 4 Jul 2018 - 4:40:59am
Karl Wilhelm Theodor Richard von Hertwig (1850-1937) Katherine Brind'Amour, Benjamin Garcia Karl Wilhelm Theodor Richard von Hertwig is an important figure in the history of embryology for his contributions of artificial hybridization of sea urchin eggs and the formulation of his coelom theory. He was born 23 September 1850 in Friedelberg, Germany, to Elise Trapp and Carl Hertwig. Richard and his older brother Oscar began their studies at Jena under the direction of Ernst Haeckel from 1868 to 1871.

Austin Bradford Hill (1897-1991) Carolina Abboud During the twentieth century, Austin Bradford Hill researched diseases and their causes in England and developed the Bradford Hill criteria, which comprise the minimal requirements that must be met for a causal relationship to be established between a factor and a disease. Hill also suggested that researchers should randomize clinical trials to evaluate the effects of a drug or treatment by monitoring large groups of people. 2017-06-15 4 Jul 2018 - 4:40:59am
August Friedrich Leopold Weismann (1834-1914) Yawen Zou August Friedrich Leopold Weismann studied how the traits of organisms developed and evolved in a variety of organisms, mostly insects and aquatic animals, in Germany in the late nineteenth and early twentieth centuries. Weismann proposed the theory of the continuity of germ-plasm, a theory of heredity. Weismann postulated that germ-plasm was the hereditary material in cells, and parents transmitted to their offspring only the germ-plasm present in germ-cells (sperm and egg cells) rather than somatic or body cells. 2014-05-23 4 Jul 2018 - 4:40:59am
Katharine McCormick (1876-1967) Aliya Buttar Katharine Dexter McCormick, who contributed the majority of funding for the development of the oral contraceptive pill, was born to Josephine and Wirt Dexter on 27 August 1875 in Dexter, Michigan. After growing up in Chicago, Illinois, she attended the Massachusetts Institute of Technology (MIT), where she graduated in 1904 with a BS in biology. That same year, she married Stanley McCormick, the son of Cyrus McCormick, inventor and manufacturer of the mechanized reaper. 2007-11-08 4 Jul 2018 - 4:40:59am
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
