Thomas Hunt Morgan

Born in Lexington, Kentucky, in 1866, Thomas Hunt Morgan became one of the central figures in early genetics. He studied at the State College of Kentucky and later earned his doctorate from Johns Hopkins University, building a career that connected zoology, embryology, and heredity.

Morgan is best known for his experiments with Drosophila melanogaster, the common fruit fly. Working with students and colleagues at Columbia University, he helped demonstrate that genes are linked to chromosomes and can be mapped, giving scientists a powerful way to understand inheritance.

In 1928 he moved to the California Institute of Technology, where he continued leading important research in biology. He received the Nobel Prize in Physiology or Medicine in 1933 for his discoveries about the role of chromosomes in heredity, and his influence helped shape genetics into a modern experimental science.
