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

The Marine Biological Laboratory, Woods Hole, Mass. 1935 B.R. Coonfield By the 1930s, the MBL had become "the" place to go during the summer for biological research and training. Luminaries such as Frank Lillie, Edmund Beecher Wilson, Edwin Grant Conklin, and Thomas Hunt Morgan took their students, packed up their families and research labs, and headed to the MBL. They worked in labs, ate together in the Mess, and they often lived in the limited on-campus housing. Life at the MBL was a life where fun, family, and science intertwined. This film, taken in 1935 by B. R. Coonfield of Brooklyn College, captures snippets of life at the MBL. 1935 4 Jul 2018 - 4:40:59am
Calvin Blackman Bridges (1889-1938) Kevin Gleason Calvin Blackman Bridges studied chromosomes and heredity in the US throughout the early twentieth century. Bridges performed research with Thomas Hunt Morgan at Columbia University in New York City, New York, and at the California Institute of Technology in Pasadena, California. Bridges and Morgan studied heredity in Drosophila, the common fruit fly. Throughout the early twentieth century, researchers were gathering evidence that genes, or what Gregor Mendel had called the factors that control heredity, are located on chromosomes. 2017-05-19 4 Jul 2018 - 4:40:59am

Chang and Eng Bunker (1811–1874) Mudhaffar Bahjat Chāng (Chang) and Ēn (Eng) Bunker were conjoined twins in the nineteenth century in the United States, the first pair of conjoined twins whose condition was well documented in medical records. A conjoined twins is a rare condition in which two infants are born physically connected to each other. In their youth, the brothers earned money by putting themselves on display as curiosities and giving lectures and demonstrations about their condition. The Bunker brothers toured around the world, including the United States, Europe, Canada, and France, and allowed physicians to examine them. 2018-01-22 4 Jul 2018 - 4:40:59am
Shinya Yamanaka (1962- ) Samuel Philbrick Shinya Yamanaka gained international prominence after publishing articles detailing the successful generation of induced pluripotent stem (iPS) cells, first in mice, then in humans. Yamanaka induced somatic cells to act like human embryonic stem cells (hESCs), allowing researchers to experiment with non-embryonic stem cells with a similar capacity as hESCs. The research involving iPS cells therefore offered new potential for research and application in medical treatment, without many of the ethical objections that hESC research entailed. 2011-04-07 4 Jul 2018 - 4:40:59am

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

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
Maurice Ralph Hilleman (1919–2005) Christian H. Ross Maurice Ralph Hilleman developed vaccines at the Merck Institute of Therapeutic Research in West Point, Pennsylvania, during the twentieth century. Over the course of his career at Merck, Hilleman created over forty vaccines, making him one of the most prolific developers of vaccine in the twentieth century. Of the fourteen vaccines commonly given to children in the US by 2015, Hilleman was responsible for eight of them. Hilleman's most widely used vaccine was his measles, mumps, and rubella (MMR) vaccine. 2017-04-13 4 Jul 2018 - 4:40:59am

Craer Rosalyn Sussman Yalow co-developed the radioimmunoassay (RIA), a method used to measure minute biological compounds that cause immune systems to produce antibodies. Yalow and research partner Solomon A. Berson developed the RIA in the early 1950s at the Bronx Veterans Administration (VA) Hospital, in New York City, New York. Yalow and Berson's methods expanded scientific research, particularly in the medical field, and contributed to medical diagnostics. For this achievement, Yalow received the Nobel Prize in Physiology or Medicine in 1977. 2013-09-10 4 Jul 2018 - 4:40:59am
William Bateson (1861-1926) Samantha Hauserman At the turn of the twentieth century, William Bateson studied organismal variation and heredity of traits within the framework of evolutionary theory in England. Bateson applied Gregor Mendel's work to Charles Darwin's theory of evolution and coined the term genetics for a new biological discipline. By studying variation and advocating Mendelian genetics, Bateson furthered the field of genetics, encouraged the use of experimental methodology to study heredity, and contributed to later theories of genetic inheritance. 2014-01-28 4 Jul 2018 - 4:40:59am
