Thomas Hunt Morgan

Thomas Hunt Morgan, born on September twenty-fifth, eighteen sixty-six, was a pioneering American evolutionary biologist and geneticist whose groundbreaking work laid the foundation for modern genetics. He earned his Ph.D. in zoology from Johns Hopkins University in eighteen ninety, where he also delved into embryology during his time at Bryn Mawr College.

In the early twentieth century, following the rediscovery of Mendelian inheritance, Morgan began his influential studies on the genetic traits of the fruit fly, Drosophila melanogaster. His research in the renowned Fly Room at Columbia University's Schermerhorn Hall revealed that genes reside on chromosomes, establishing them as the mechanical basis of heredity. This pivotal discovery earned him the Nobel Prize in Physiology or Medicine in nineteen thirty-three.

Throughout his illustrious career, Morgan authored twenty-two books and three hundred seventy scientific papers, significantly contributing to the field of genetics. His work with Drosophila not only made it a key model organism in genetics but also led to the establishment of the Division of Biology at the California Institute of Technology, which has since produced seven Nobel Prize winners.
