Alfred Sturtevant

Alfred Sturtevant, born on November 21, 1891, was a pioneering American geneticist and botanist whose contributions to the field of genetics have left an indelible mark. In 1911, he achieved a remarkable feat by constructing the first genetic map of a chromosome, a groundbreaking advancement that laid the foundation for future genetic research.

Throughout his illustrious career, Sturtevant collaborated closely with renowned scientist Thomas Hunt Morgan, focusing on the organism Drosophila melanogaster. His innovative approach involved observing the development of these flies, particularly in cases where the earliest cell division resulted in two distinct genomes. This meticulous observation allowed him to measure the embryonic distance between organs, leading to the creation of a unit of measurement known as the 'sturt,' named in his honor.

Sturtevant's contributions to science were recognized at the highest levels. On February 13, 1968, he was awarded the National Medal of Science for the year nineteen sixty-seven by President Lyndon B. Johnson, a testament to his significant impact on the field of genetics and his dedication to advancing scientific knowledge.
