Haldan Keffer Hartline

Haldan Keffer Hartline was born on December 22, 1903 in Bloomsburg, Pennsylvania, US, United States, is Physiologist. Haldan Keffer Hartline was an American physiologist who was awarded the Nobel Prize in Physiology or Medicine in 1967 for his work on analyzing the neurophysiological mechanism of vision. He shared the coveted prize with George Wald and Ragnar Granit. Hartline spent decades studying the optic nerves of frogs and horseshoe crabs. He became the first scientist to isolate and record the activity of a single optic nerve fibre. He later showed that different fibres in the optic nerves respond to light in different ways. Hartline’s inclination towards physiology or medicine started early. His parents were professors at the State Normal School (now Bloomsburg State College). His father who was a Professor in Biology inspired Hartline to take up Natural Sciences. Since the beginning of his career, Hartline dedicated his time to research on cellular-level electrical activity within the eye. Other than scientific research, he also held several academic positions in his life. He was a Professor of Biophysics at the John Hopkins University and later Professor of Neurophysiology at the Rockfeller Institute.
