Haldan Keffer Hartline, a renowned physiologist based in the United States, is estimated to have a net worth ranging from $100,000 to $1 million by 2024. Recognized for his significant contributions to the field of physiology, Hartline's research and findings have shaped our understanding of vision and neural processes. As a Nobel laureate, his work on the neural mechanisms underlying vision has earned him international acclaim. With such achievements and accolades, it comes as no surprise that Hartline's net worth reflects his valuable contributions to the scientific community.
Hartline was elected a Foreign Member of the Royal Society (ForMemRS) in 1966. He was awarded the Nobel Prize in Physiology or Medicine in 1967.
Hartline received his undergraduate education from Lafayette College in Easton, Pennsylvania, graduating in 1923. He began his study of retinal electrophysiology as a National Research Council Fellow at Johns Hopkins University, Baltimore, receiving his Doctor of Medicine (MD) degree in 1927.
After attending the universities of Leipzig and Munich as an Eldridge Johnson traveling research scholar from the University of Pennsylvania, he returned to the US to take a position in the Eldridge Reeves Johnson Foundation for Medical Physics at Penn, which was under the directorship of Detlev W. Bronk at that time. In 1940–1941, he was Associate Professor of Physiology at Cornell Medical College in New York City, but returned to Penn and stayed until 1949. Then he became professor of biophysics and chairman of the department at Johns Hopkins in 1949. One of Hartline's graduate students at Johns Hopkins, Paul Greengard, who also won the Nobel Prize. Hartline joined the staff of Rockefeller University, New York City, in 1953 as professor of neurophysiology.
Hartline was elected a Foreign Member of the Royal Society (ForMemRS) in 1966. He was awarded the Nobel Prize in Physiology or Medicine in 1967.
