Thomas Hunt Morgan (September 25, 1866 – December 4, 1945) was an American geneticist and embryologist. Morgan received his PhD from Johns Hopkins University in 1890 and researched embryology during his tenure at Bryn Mawr. Following the rediscovery of Mendelian inheritance in 1900, Morgan’s research moved to the study of mutation in the fruit fly Drosophila melanogaster. In his famous Fly Room at Columbia University Morgan was able to demonstrate that genes are carried on chromosomes and are the mechanical basis of heredity. These discoveries formed the basis of the modern science of genetics. When he was awarded the Nobel Prize in Physiology or Medicine in 1933 he was the first person awarded the Prize in genetics, for his discoveries concerning the role played by the chromosome in heredity.
