Thomas Hunt Morgan Facts
Thomas Hunt Morgan (September 25, 1866 to December 4, 1945) was an American evolutionary biologist, geneticist, and embryologist. He won the Nobel Prize in Physiology or Medicine in 1933 for "his discoveries concerning the role played by the chromosome in heredity."
Interesting Thomas Hunt Morgan Facts:
Thomas Hunt Morgan was born in Lexington, Kentucky, and was the eldest son.
As a child he was interested in natural history and began to collect birds, bird eggs and fossils.
In 1886 he earned his B.S. at the University of Kentucky
He transferred to Johns Hopkins University for his graduate work.
In 1887 he worked at the seashore laboratory of Alphaeus Hyatt in Massachusetts.
The next year he was a research for the United States fish Commission at Woods Hole.
The summer of 1890 he worked at the Marine Biological Laboratory at Woods Hole.
He subsequently spent many summers there as an investigator.
In 1890 he earned his PhD in zoology at Johns Hopkins and he received the Adam Bruce Fellowship.
He used it to travel to Europe where he worked at the Marine Zoological Laboratory in Naples.
He returned to Naples in 1895 and 1900.
While at Naples he met Hans Driesch who influenced him to study embryology.
From 1891 to 1904 he was Associate Professor of Biology at Bryn Mawr College.
In 1904 he became Professor of Experimental Zoology at Columbia University.
From 1928 to 1945 he was Director of the G.Kerckhoff Laboratories and Professor of Biology at Caltech.
While at Columbia Morgan studied the effect of cytology on biology.
He was critical of the idea that gametes are pure and uncrossed.
In 1909 he had begun his study of Drosophila melanogaster.
He chose this particular animal for his study of genetics since it was cheap and took up little room in his cramped laboratory.
Shortly after he began his study of them, several mutants occurred in the flies.
From his study of the mutant flies he was able to determine the precise behavior and location of the responsible genes.
He published a paper on sex linkage on eye color in Drosophila.
Morgan bred the flies by the millions and carefully analyzed the results.
He discovered that mutations spontaneously appeared.
In 1915 he published Mechanism of Mendelian Heredity and theorized that genes are linearly arranged in the chromosomes.
His other books include The Physical Basis of Heredity (1919), Embryology and Genetics (1924), Evolution and Genetics (1925), The Theory of the Gene (1926) and The Scientific Basis of Evolution.
In addition to the Nobel Prize he received the Darwin Medal and the Copley Medal in recognition of his enormous contribution to the field of genetics.
