Biography
Haldan Keffer Hartline was a pioneering American physiologist renowned for his groundbreaking research in the field of neurophysiology, particularly in understanding the mechanisms of vision. Born in Bloomsburg, Pennsylvania, Hartline developed an early interest in science, which led him to pursue a degree in medicine at Johns Hopkins University, where he earned his MD in 1927. He later studied at the University of Leipzig and the University of Munich, where he honed his skills in electrophysiology. Hartline’s most notable work involved studying the electrical responses of single nerve fibers in the eye to light stimulation. His meticulous experiments on the horseshoe crab (Limulus polyphemus) provided significant insights into how photoreceptor cells in the retina process and transmit visual information. For his contributions to our understanding of the visual system, Hartline was awarded the Nobel Prize in Physiology or Medicine in 1967, alongside George Wald and Ragnar Granit. Throughout his career, Hartline held prestigious positions at various institutions, including Johns Hopkins University, Cornell University, and the Rockefeller Institute. His research has had a lasting impact on both neuroscience and ophthalmology, influencing generations of scientists.
