Known for his triangular theory of love and his triarchic theory of intelligence, this one-time President of the American Psychological Association contributed greatly to the fields of psychology and psychometrics. He taught at Cornell University, Oklahoma State University, and Yale University, among other institutions of higher learning.
As a child, he struggled with test-taking anxiety, an issue that spurred his interest in psychology and intelligence and aptitude testing. He later earned degrees in psychology from Yale University and Stanford University.
In 2013, he voluntarily resigned as President of the University of Wyoming after having held the office for only four months.
He was married several times. One of his wives, Elena Grigorenko, taught psychology at Yale University, and another, Karin Sternberg, was a German-born psychologist.
He and Jerome Bruner both made significant contributions to the field of cognitive psychology.
