Katharine McCormick (1876-1967)
By 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.

Robert William Briggs (1911-1983)
By 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.

"Experiments on the Development of Chick and Duck Embryos, Cultivated in vitro" (1932), by Conrad Hal Waddington
By Adam R. Navis
Conrad Hal Waddington's "Experiments on the Development of Chick and Duck Embryos, Cultivated in vitro," published in 1932 in Philosophical Transactions of the Royal Society of London, Series B, compares the differences in the development of birds and amphibians. Previous experiments focused on the self differentiation of individual tissues in birds, but Waddington wanted to study induction in greater detail. The limit to these studies had been the amount of time an embryo could be successfully cultivated ex vivo.

Rita Levi-Montalcini (1909-2012)
By Adam R. Navis
Rita Levi-Montalcini is a Nobel Laureate recognized for her work in the discovery and characterization of nerve growth factor. Nerve growth factor (NGF) promotes the growth and maintenance of the nervous system in a developing system. The majority of her career has been devoted to investigating the many aspects of NGF.

Viktor Hamburger (1900-2001)
By Adam R. Navis
Viktor Hamburger was an embryologist who focused on neural development. His scientific career stretched from the early 1920s as a student of Hans Spemann to the late 1980s at Washington University resolving the role of nerve growth factor in the life of neurons. Hamburger is noted for his systematic approach to science and a strict attention to detail. Throughout his life he maintained an interest in nature and the arts, believing both were important to his scientific work.

Washington University in St. Louis
By Adam R. Navis
Washington University in St. Louis served as the backdrop for many scientific discoveries, including that of nerve growth factor (NGF). Many of the accomplishments in embryology at Washington University can be attributed to the influence of Viktor Hamburger. He served as chair of the zoology department for twenty-five years. One of the few Nobel Prizes given for embryological research was awarded to faculty members Hamburger hired; Rita Levi-Montalcini and Stanley Cohen won for their role in the discovery of nerve growth factor.

Hanging Drop Tissue Culture
By Adam R. Navis
The hanging drop tissue culture is a technique utilized in embryology and other fields to allow growth that would otherwise be restricted by the flat plane of culture dishes and also to minimize the surface area to volume ratio, slowing evaporation. The classic hanging drop culture is a small drop of liquid, such as plasma or some other media allowing tissue growth, suspended from an inverted watch glass. The hanging drop is then suspended by gravity and surface tension, rather than spreading across a plate.

"Experiments in Transplanting Limbs and Their Bearing Upon the Problems of the Development of Nerves" (1907), by Ross Granville Harrison
By Adam R. Navis
In his 1907 paper, "Experiments in Transplanting Limbs and Their Bearing Upon the Problems of the Development of Nerves," in the Journal of Experimental Zoology that he edited, Ross Granville Harrison tested the development of nerves in transplanted tissue. He studied neural development by examining two competing theories. Victor Hensen proposed a syncytial theory as a way to explain neural development, suggesting that all the nerves of an embryo were connected directly by cytoplasm laid down early in development, and leaving no room for later modification.

Min Chueh Chang (1908-1991)
By Kimberly A. Buettner
As one of the researchers involved in the development of the oral contraceptive pill, Min Chueh Chang helped to revolutionize the birth control movement. Although best known for his involvement with "the pill," Chang also made a number of discoveries throughout his scientific career involving a range of topics within the field of reproductive biology. He published nearly 350 articles in scientific journals.

Franklin Paine Mall (1862-1917)
By Kimberly A. Buettner
Franklin Paine Mall was born into a farming family in Belle Plaine, Iowa, on 28 September 1862. While he attended a local academy, an influential teacher fueled Mall's interest in science. From 1880-1883, he studied medicine at the University of Michigan, attaining his MD degree in 1883. William J. Mayo, who later became a famous surgeon and co-founder of the Mayo Clinic in Rochester, Minnesota, was a classmate of Mall's. Throughout his studies at Michigan, he was influenced by Corydon L. Ford, a professor of anatomy, Victor C.
