Biography
Haldan Keffer Hartline was an American physiologist renowned for his pioneering work in neurophysiology, specifically in understanding the mechanisms of vision. Born on December 22, 1903, in Bloomsburg, Pennsylvania, Hartline’s early interest in biology led him to earn an A.B. degree in 1923 from Lafayette College. He furthered his education at Johns Hopkins University, obtaining a Ph.D. in 1927. Hartline’s research career was marked by significant contributions to the understanding of how nerve cells in the eye respond to light. He conducted groundbreaking experiments on the horseshoe crab (Limulus polyphemus), which provided critical insights into the processing of visual information. His work elucidated the fundamental principles of retinal processing and photoreceptor activity, forming the basis for much of modern visual science. In 1967, Hartline was awarded the Nobel Prize in Physiology or Medicine, sharing it with Ragnar Granit and George Wald for their discoveries concerning the primary physiological and chemical visual processes in the eye. Throughout his career, Hartline held academic positions at Johns Hopkins University, the University of Pennsylvania, and Rockefeller University.
