American zoologist and geneticist, famous for his experimental research with the fruit fly (Drosophila) by which he established the chromosome theory of heredity. He showed that genes are linked in a series on chromosomes and are responsible for identifiable, hereditary traits. Morgan’s work played a key role in establishing the field of genetics. He received the Nobel Prize for Physiology or Medicine in 1933. In 1924 Morgan received the Darwin Medal, and in 1939 he was awarded the Copley Medal by the Royal Society of London, of which he was a foreign member. In 1927–31 he served as president of the National Academy of Sciences; in 1930 of the American Association for the Advancement of Science; and in 1932 of the Sixth International Congress of Genetics. He remained on the faculty at Caltech until his death on 4 December 1945.
Morgan was a many-sided character who was, as a student, critical and independent. He was a skeptic. He hated speculation and disregarded what there wasn’t evidence to support. Early on, he was actually a critic of Mendelian genetics and Darwin’s explanation for evolution. He set out to prove an alternative hypothesis for heredity but his data only confirmed Mendels results and filled in the gap in Darwin’s Theory of Evolution By Natural Selection regarding the mechanics of inheritance. In 1916, he wrote A Critique of the Theory of Evolution which laid out the detailed genetic mechanism for the inheritance of variations and thus placed a major missing puzzle piece into Darwin’s theory.
