Norman Haire (1892-1952) Claudia Nunez-Eddy Norman Haire was a physician who advocated for eugenics, which is the betterment of human population by promoting positive traits, and birth control rights in the twentieth century in both Australia and the UK. In the UK, Haire joined the Malthusian League, a contraception advocacy organization, and helped the League open the first physician-supervised birth control clinic, called Walworth Women’s Welfare Centre in London, England. 2017-04-13 4 Jul 2018 - 4:40:59am
Norbert Freinkel (1926–1989) Blaise Castagnetti During the twentieth century, Norbert Freinkel studied hormones and diabetes in the US. Freinkel conducted many experiments that enabled him to determine the factors that influence hormones of the thyroid gland to bind to proteins and to determine the effects that those thyroid hormones have on surrounding tissues. Furthermore, Freinkel researched gestational diabetes, which is diabetes that occurs for the first time during a women’s pregnancy. That type of diabetes is caused by a change in the way a woman’s body responds to insulin, a hormone made in the body. 2018-01-16 4 Jul 2018 - 4:40:59am

Nikolai Ivanovic Vavilov (1887-1943) Marci Baranski Nikolai Ivanovich Vavilov proposed theories of plant genetic diversity and participated in the political debate about genetics in Soviet Russia in the early twentieth century. Vavilov collected plant species around the world, building one of the first and most comprehensive seed banks, and he spent much of his life researching plant breeding and genetics. Vavilov also developed a theory of the historical centers of origin of cultivated plants. Vavilov spent most of his scientific career in Russia, although he studied abroad and traveled extensively. 2014-04-15 4 Jul 2018 - 4:40:59am

Nicole Marthe Le Douarin (1930- ) Brad Jacobson Nicole Marthe Le Douarin was one of the first progressive female pioneers of developmental and embryological research. Some of her most notable and ground-breaking work involves grafting quail and chicken embryos together in order to study the developmental fate of each contributing embryo. Le Douarin was born in Brittany, France, on 20 August 1930. As an only child she was inspired by her mother, a school teacher at the time, to develop a passion for learning. 2010-11-17 4 Jul 2018 - 4:40:59am
Nicolaas Hartsoeker (1656-1725) Cera R. Lawrence Nicolaas Hartsoeker, a Dutch astronomer, optics manufacturer, and naturalist, was born 26 March 1656 in Gouda, Netherlands, and died 10 December 1725. His mother was Anna van der Mey and his father was Christiaan Hartsoeker, a prominent evangelical minister. His major contribution to embryology was his observations of human sperm cells, which he claimed to be the first to see under a microscope. His sketch of the homunculus, a tiny preformed human he believed to exist in the head of spermatazoa, is his lasting scientific legacy in the field of embryology. 2008-09-26 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

Muriel Wheldale Onslow (1880-1932) Samantha Hauserman Muriel Wheldale Onslow studied flowers in England with genetic and biochemical techniques in the early twentieth century. Working with geneticist William Bateson, Onslow used Mendelian principles and biochemical analysis together to understand the inheritance of flower colors at the beginning of the twentieth century. Onslow's study of snapdragons, or Antirrhinum majus, resulted in her description of epistasis, a phenomenon in which the phenotypic effect of one gene is influenced by one or more other genes. She discovered several biochemicals related to color formation. 2013-10-17 4 Jul 2018 - 4:40:59am

Milan Vuitch (1915–1993) Victoria Higginbotham Milan Vuitch was an abortion provider in the twentieth century, who performed thousands of abortions in Washington, DC, at a time when abortions were legal only if they preserved the life or health of the pregnant woman. Vuitch was a frequent critic of Washington DC’s anti-abortion law and was arrested multiple times for providing abortions that were not considered necessary to preserve the pregnant woman’s life. After several arrests, Vuitch challenged the law under which he had been arrested, and his case made its way to the Supreme Court in Vuitch v. United States. 2018-06-09 4 Jul 2018 - 4:40:59am

Max Ludwig Henning Delbruck (1906–1981) Victoria Hernandez Max Ludwig Henning Delbrick applied his knowledge of theoretical physics to biological systems such as bacterial viruses called bacteriophages, or phages, and gene replication during the twentieth century in Germany and the US. Delbrück demonstrated that bacteria undergo random genetic mutations to resist phage infections. Those findings linked bacterial genetics to the genetics of higher organisms. In the mid-twentieth century, Delbrück helped start the Phage Group and Phage Course in the US, which further organized phage research. 2017-09-20 4 Jul 2018 - 4:40:59am
