Charles Burnham (geneticist)
Charles Russell Burnham (1904–1995) was an American plant geneticist who studied maize cytology and genetics. In 1968 he was elected a fellow of the American Society of Agronomy. After his retirement he played a critical role in developing a blight resistant strain of the American chestnut. Early life and education Burnham was born in Hebron, Wisconsin in 1904 and grew up in Fort Atkinson, Wisconsin. He attended college first at the University of Minnesota for two years, then transferring to the University of Wisconsin where he earned his BA in 1924, and MS in 1925. He became a graduate assistant of RA Brink studying maize genetics and earned a PhD in genetics with a minor in Plant Pathology in 1929. At this point, he received a National Research Fellowship to travel to Cornell University where he studied under Rollins A. Emerson and alongside Marcus Rhoades and future Nobel Prize winners Barbara McClintock and George Beadle. After Cornell, Burnham went on to work at ...

Hebron, Wisconsin
Hebron is a town in Jefferson County, Wisconsin, United States. The population was 1,043 at the 2020 census. The census-designated place of Hebron is located in the town. History The first steps toward the settlement of the town of Hebron, state of Wisconsin, Jefferson County, was made by the Rock river claim company, who, December 20th, 1835, made a claim of about half a section of land on section 2, embracing a water-power formed by Bark river. This company consisted of sixteen persons, among whom were, Solomon Juneau, Dwight Foster, Jonas Folts, Enoch G. Darling, Elisha W. Ajitant David Sergeant, Milo Jones, George Homer, Lu I.

The American Chestnut Foundation
The American Chestnut Foundation (TACF) is a nonprofit American organization dedicated to breeding a blight-resistant American chestnut (''Castanea dentata'') tree and the reintroduction of this tree to the forests of the Eastern United States. The mission of The American Chestnut Foundation (TACF) is to restore the American chestnut tree to the forests of Eastern North America by breeding genetically diverse blight-resistant trees, evaluating various approaches to the management of chestnut pests and pathogens, and reintroducing the trees into the forest in an ecologically acceptable manner. The American chestnut tree once comprised a quarter of the eastern hardwood forest from Maine to Georgia and west to the Ohio River Valley, providing a valuable economic resource in both timber and nuts, as well as an abundant food source for wildlife. An accidentally imported Asiatic chestnut blight decimated approximately four billion trees, with devastating results to Appalachian commu ...

Lewis Stadler
Lewis John Stadler (July 6, 1896 – May 12, 1954) was an American geneticist. His research focused on the mutagenic effects of different forms of radiation on economically important plants like maize and barley. Biography Lewis John Stadler was born in St. Louis, Missouri, in 1896 to Henry Louis and Josephine Ehrman Stadler. Stadler's early education efforts were unremarkable, but two summers worked on Midwestern farms sparked an interest in agriculture. He began his undergraduate work at the University of Missouri and completed a B.S. in agriculture at the University of Florida (1917). Afterwards, he returned to the University of Missouri and earned the A.M. (1918). Post-A.M., he enrolled in the Field Artillery of the United States Army, although his commission as Second Lieutenant was not used in overseas duty due to the end of World War I. Stadler spent 1919 in graduate studies at Cornell University under Harry Houser Love and Rollins A. Emerson. He returned again to the U ...

Edward Murray East
Edward Murray East (October 4, 1879 – November 9, 1938) was an American plant geneticist, botanist, agronomist and eugenicist. He is known for his experiments that led to the development of hybrid corn and his support of 'forced' elimination of the 'unfit' based on eugenic findings. He worked at the Bussey Institute of Harvard University where he performed a key experiment showing the outcome of crosses between lines that differ in a quantitative trait. Work in eugenics Edward Murray East was a prominent figure in early American genetics and a strong supporter of the eugenics movement in the United States. He was strongly influenced by the work of Thomas Malthus, especially '' Essay on the Principle of Population'' (1798). This influence led East to create many of his ideas concerning birth control and immigration policy. He applied many of the ideas that he had developed in his research on the applications of genetics to agriculture to his ideas about human society. East ...

George Beadle
George Wells Beadle (October 22, 1903 – June 9, 1989) was an American geneticist. In 1958 he shared one-half of the Nobel Prize in Physiology or Medicine with Edward Tatum for their discovery of the role of genes in regulating biochemical events within cells. He also served as the 7th President of the University of Chicago. Beadle and Tatum's key experiments involved exposing the bread mold ''Neurospora crassa'' to x-rays, causing mutations. In a series of experiments, they showed that these mutations caused changes in specific enzymes involved in metabolic pathways. These experiments led them to propose a direct link between genes and enzymatic reactions, known as the One gene-one enzyme hypothesis. Education and early life George Wells Beadle was born in Wahoo, Nebraska. He was the son of Chauncey Elmer Beadle and Hattie Albro, who owned and operated a farm nearby. George was educated at the Wahoo High School and might himself have become a farmer if one of his teachers a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barbara McClintock
Barbara McClintock (June 16, 1902 – September 2, 1992) was an American scientist and cytogeneticist who was awarded the 1983 Nobel Prize in Physiology or Medicine. McClintock received her PhD in botany from Cornell University in 1927. There she started her career as the leader of the development of maize cytogenetics, the focus of her research for the rest of her life. From the late 1920s, McClintock studied chromosomes and how they change during reproduction in maize. She developed the technique for visualizing maize chromosomes and used microscopic analysis to demonstrate many fundamental genetic ideas. One of those ideas was the notion of genetic recombination by crossing-over during meiosis—a mechanism by which chromosomes exchange information. She produced the first genetic map for maize, linking regions of the chromosome to physical traits. She demonstrated the role of the telomere and centromere, regions of the chromosome that are important in the conservation of gen ...
