Timeline

1913

Roger Wolcott Sperry (August 20, 1913 – April 17, 1994) was an American neuropsychologist, neurobiologist, cognitive neuroscientist, and Nobel laureate who, together with David Hunter Hubel and Torsten Nils Wiesel, won the 1981 Nobel Prize in Physiology and Medicine for his work with split-brain research.

1935

He received his bachelor's degree in English in 1935 and a master's degree in psychology in 1937.

1941

He received his Ph.D. in zoology from the University of Chicago in 1941, supervised by Paul A. Weiss.

Sperry then did postdoctoral research with Karl Lashley at Harvard University though most of his time was spent with Lashley at the Yerkes Primate Research Center in Orange Park, Florida.

1942

In 1942, Sperry began work at the Yerkes Laboratories of Primate Biology, then a part of Harvard University.

There he focused on experiments involving the rearranging of motor and sensory nerves.

1946

He left in 1946 to become an assistant professor, and later associate professor, at the University of Chicago.

1949

In 1949, during a routine chest x-ray, there was evidence of tuberculosis.

He was sent to Saranac Lake in the Adironack Mountains in New York for treatment.

1952

It was during this time when he began writing his concepts of the mind and brain, and was first published in the American Scientist in 1952.

In 1952, he became the Section Chief of Neurological Diseases and Blindness at the National Institutes of Health and finished out the year at the Marine Biology Laboratory in Coral Gables, Florida.

Sperry went back to The University of Chicago in 1952 and became an Associate Professor of Psychology.

He was not offered tenure at Chicago and planned to move to Bethesda, Maryland but was held up by a delay in construction at the National Institutes of Health.

During this time Sperry's friend Victor Hepburn invited him to lecture about his research at a symposium.

There were professors from the California Institute of Technology in the audience of the symposium who, after listening to Sperry's lecture, were so impressed with him they offered him a job as the Hixson Professor of Psychobiology.

1954

In 1954, he accepted the position as a professor at the California Institute of Technology (Caltech as Hixson Professor of Psychobiology) where he performed his most famous experiments with Joseph Bogen, MD and many students including Michael Gazzaniga.

Under the supervision of Paul Weiss while earning his Ph.D. at the University of Chicago, Sperry became interested in neuronal specificity and brain circuitry and began questioning the existing concepts about these two topics.

He asked the simple question first asked in his Introduction to Psychology class at Oberlin: Nature or nurture?

He began a series of experiments in an attempt to answer this question.

Sperry crosswired the motor nerves of rats' legs so the left nerve controlled the right leg and vice versa.

He would then place the rats in a cage that had an electric grid on the bottom separated into four sections.

Each leg of the rat was placed into one of the four sections of the electric grid.

A shock was administered to a specific section of the grid, for example the grid where the rat's left back leg was located would receive a shock.

Every time the left paw was shocked the rat would lift his right paw and vice versa.

2002

A Review of General Psychology survey, published in 2002, ranked Sperry as the 44th most cited psychologist of the 20th century.

Sperry was born in Hartford, Connecticut, to Francis Bushnell and Florence Kraemer Sperry.

His father was in banking, and his mother trained in business school.

He was raised in an upper middle-class environment, which stressed academic achievement.

Roger had one brother, Russell Loomis.

Their father died when Roger was 11.

Afterwards, his mother became assistant to the principal in the local high school.

Sperry went to Hall High School in West Hartford, Connecticut, where he was a star athlete in several sports, and did well enough academically to win a scholarship to Oberlin College.

At Oberlin, he was captain of the basketball team, and he also took part in varsity baseball, football, and track.

He also worked at a cafe on campus to help support himself.

Sperry was an English major, but he took an Intro to Psychology class taught by a Professor named R. H. Stetson who had worked with William James, the father of American Psychology.

This class sparked Sperry's interest in the brain and how it can change.

Stetson was disabled and had trouble getting around so Sperry would help him out by driving him to and from wherever he needed to go.

This included taking Stetson to lunch with his colleagues.

Sperry would just sit at the end of the table and listen to Stetson and his colleagues discuss their research and other psychological interests.

This increased Sperry's interest in Psychology even more and after he received his undergraduate degree in English from Oberlin he decided to stay and get his master's degree in Psychology.
