Moran Flies for the Prize Do all fruit flies look identical? Perhaps some have larger wings, darker color, white or red eyes? True, fruit flies are tiny, but if you ask Thomas Hunt Morgan, he would know. Nobel Prize wining scientist Thomas Hunt Morgan was born on September 25,1866, in Lexington, Kentucky. He graduated from State College ( now the University of Kentucky) and received a doctorate from John Hopkins University in Baltimore. In 1904, as a professor of Experimental Zoology at Columbia University, Dr. Morgan began the research into heredity that would later earn him worldwide acclaim. In 1933, he was awarded the Nobel Prize in medicine, the first one ever given to a non-physician. Fascinated by Gregor Mendel's studies in pea heredity, Morgan wanted to know more about how traits of the parent are passed to their offspring. Since the common fruit fly produces over thirty generations per year it was ideal for Morgan's studies. By crossbreeding, inbreeding,and backbreeding thousands of flies and carefully observing the traits passed from generation to generation, Morgan and his colleagues formed the Chromosome Theory of Heredity. This theory is the basis for a branch of biology called Genetics. Genetics

Thomas Hunt Morgan (1866-1945) Along with Bateson , the co-founder of modern genetics. An experimentalist and originally a mutationist, opposed to natural selection, Lamarckism, orthogenesis, and the chromosomal theory of inheritance. He converted to the latter and to Darwinism after 1910, discovered linkage and recombination with his "fly room" students and colleagues, and was the first to show that variation derives from numerous small mutations. Most of the "fly room" research during its glory years in the 1910s and 20s was focused on using linkage data to map genes onto the chromosomes of Drosophila melanogaster, a completely novel research agenda that replaced the earlier, neo-Mendelian emphasis on creating quasi-chemical genetic formulas. In 1928 Morgan moved his team of drosophilists (including most prominently Sturtevant and Bridges) to Cal Tech. This program soon recruited Dobzhansky , continuing its leadership in the field until Bridges' death, Morgan's retirement, and Dobzhansky's departure in the late 1930's. Foe of Osborn , who had gotten him hired at Columbia; Morgan did flirt with the eugenics movement in the 1910s, but he opposed it during its ascendancy in the 1920s. Friendly with

Hunt-Morgan Photograph Collection Biographical Sketch Biographical Sketch The Hunt-Morgan family of central Kentucky produced both Brigadier General John Hunt Morgan and the Nobel Prize-winning geneticist Thomas Hunt Morgan. Both the Hunt and the Morgan families were heavily involved in agriculture and mercantile businesses along the Allegheny frontier in the early history of the nation, expanding into central Kentucky in the mid-nineteenth century and becoming major producers of hemp, tobacco, and horses. John Wesley Hunt, grandfather of John Hunt Morgan, became one of the wealthiest men in the western part of the country, involved in banking, mercantile interests, manufacturing and agriculture. By 1801 Hunt had become a leading landowner and businessman in Fayette County, Kentucky, founding a hemp factory in 1803 and expanding his business empire to include commissioned merchandising of hemp fiber, salt peter and tobacco in 1810. Hunt’s banking interests included the Bank of the United States, where he served as director of the Lexington branch in 1817 and president of the Farmers and Mechanics Bank of Lexington in 1818. His philanthropic concerns led him to serve on the Board of Trustees of Transylvania University for sixteen years and to aid in the establishment of the Lunatic Asylum in Lexington, Kentucky in 1820, serving as Chairman of the Board of that institution for twenty years. John Wesley Hunt died in 1849, a suspected victim of cholera. The Morgan family was noted for their military service, its members serving with distinction in the Revolution and the War of 1812 and as intrepid frontiersmen, loving the outdoors and living close to the land. John Hunt Morgan excelled as a horseman from a childhood spent on a Bluegrass farm along Tates Creek Pike, Fayette County, Kentucky and served in the First Kentucky Cavalry with his brother Calvin and his uncle Alexander Morgan in the Mexican War. On his return, John Hunt Morgan exhibited the talents of his Hunt relations and engaged in a profitable hemp factory and woolen mill.

Morgan (Thomas Hunt) Symposium Collection Biographical Sketch Biographical Sketch Morgan's early career was spent in natural history. He got his Ph.D. at Johns Hopkins. In 1891, Morgan began teaching at Bryn Mawr, where he met Jacques Loeb, and stayed until 1904. From morphology, his research interests shifted to experimental embryology (1891-94). Morgan became a devotee of Entwicklungsmechanik, or developmental mechanics. After 1900 he was also critical of Mendelism and the chromosomal theory of heredity. In about 1908, Morgan began working with Drosophila . It was probably Frank Lutz, a geneticist at the Carnegie Institution of Washington's Station for Experimental Evolution at Cold Spring Harbor, who introduced Morgan to the fruitfly Drosophila . He began using what was still basically a wild-type fly in experimental evolutionary studies. Morgan selected for specific phontypic mutants in an effort to determine their selective value. The goal was to determine how heredity influenced evolution. In 1915, Morgan, Bridges, and Sturtevant published The Mechanism of Mendelian Heredity , a defining tome that established Drosophila as a key model system in genetics and set the standard for Mendelian gene mapping efforts. In 1928, Morgan moved his group to Caltech, where they remained until Morgan's death. Morgan won the 1933 Nobel Prize in Physiology or Medicine.

Themes Arts Sci-Philately Heredity and the Genetic Code Thomas Hunt Morgan Used with permission of Maiken Naylor, University at Buffalo, Buffalo, NY, USA, http://ublib.buffalo.edu/libraries/units/sel/exhibits/stamps The Swedish stamps above offer insights into the Nobel prize winning work done by the scientists listed below: Thomas Hunt Morgan (1866-1945) was aware of Mendel's work, which had just been rediscovered, and performed his own genetic experiments, not with peas, but with fruit flies, which could reproduce rapidly and in great numbers and had only four pairs of chromosomes. He found that Mendel's Law of the independent assortment of characters was true, but that in some cases a linkage existed between characters. The extent of linkage between characters was a measure of their position, or nearness to each other, on the same chromosome. Mapping the genes and their positions in the chromosomes explained the range of Mendelian results. Morgan won the 1933 Nobel prize in physiology or medicine. Francis Crick, James D. Watson, and Maurice Wilkins determined the molecular structure of DNA as a double helix or two intertwined spirals of phosphate and sugar molecules linked by pairs of organic bases. The sequences of the paired organic bases form the genetic code of an organism. The double helix structure is an eye-catching symbol that appears on many stamps, including the Czech Mendel stamp above, and examples from Liechtenstein and Israel below.

Morgan, Thomas Hunt US geneticist who helped establish that the genes are located on the chromosomes, discovered sex chromosomes, and invented the techniques of genetic mapping. He was the first to work on the fruit fly Drosophila, which has since become a major subject of genetic studies. Nobel Prize for Physiology or Medicine 1933. Morgan was born in Lexington, Kentucky, and studied at Johns Hopkins University. He was professor of experimental zoology at Columbia University 1904-28, when he was appointed director of the Laboratory of Biological Sciences at the California Institute of Technology. Following the rediscovery of Austrian scientist Gregor Mendel's work), Morgan's interest turned from embryology to the mechanisms involved in heredity, and in 1908 he began his research on the genetics of Drosophila. From his findings he postulated that certain characteristics are sex-linked, that the X-chromosome carries several discrete hereditary units (genes), and that the genes are linearly arranged on chromosomes. He also demonstrated that sex-linked characters are not invariably inherited together, from which he developed the concept of crossing-over and the associated idea that the extent of crossing-over is a measure of the spatial separation of genes on chromosomes. Morgan published a summary of his work in The Mechanism of Mendelian Heredity 1915.

Thomas Hunt Morgan (1866-1945) received the Nobel Prize in Medicine or Physiology in 1933 for his discoveries concerning the role chromosomes play in heredity. At the beginning of his career, however, Morgan spent considerable time and effort on the study of embryogenesis and regeneration, and published several important articles and books on these subjects. Of relevance to us is his 1901 book appropriately entitled "Regeneration". The work and ideas presented in this book remain relevant to the modern study of regeneration, and many of the incisive questions postulated in this work remain unanswered to this day. However, Morgan eventually abandoned the study of regeneration since, in his own words, he felt that "we will never understand the phenomena of development and regeneration" (Berrill, N. J.

Thomas Hunt Morgan (1866-1945) establishes the chromosomal theory of heredity. Thomas Hunt Morgan, an embryologist who had turned to research in heredity, in 1907 began to extensively breed the common fruit fly, Drosophila melanogaster. He hoped to discover large-scale mutations that would represent the emergence of new species. As it turned out, Morgan confirmed Mendelian laws of inheritance and the hypothesis that genes are located on chromosomes. He thereby inaugurated classical experimental genetics. After breeding millions of Drosophila in his laboratory at Columbia University, in 1910 Morgan noticed one fruit fly with a distinctive characteristic: white eyes instead of red. He isolated this specimen and mated it to an ordinary red-eyed fly. Although the first generation of 1,237 offspring was all red-eyed but for three, white-eyed flies appeared in larger numbers in the second generation. Surprisingly, all white-eyed flies were male. Thomas Hunt Morgan These results were suggestive for hypotheses of which Morgan himself was skeptical. He was at the time critical of the Mendelian theory of inheritance, mistrusted aspects of chromosomal theory, and did not believe that Darwin's concept of natural selection could account for the emergence of new species. But Morgan's discoveries with white- and red-eyed flies led him to reconsider each of these hypotheses.
