NEW YORK -- Howard Ernest Gruber, a scholar of cognitive psychology who was also noted for his writings on the development of Darwin's theories on evolution, died of pneumonia in Manhattan Jan. 25 at age 82.
Mr. Gruber dedicated his life to the study of cognition, a process of knowing that includes both awareness and judgment. He became known for his study of Darwin's thinking as he used observations of natural selection to create the theory of evolution.
With a PhD in psychology from Cornell, he taught at the University of Colorado and the New School for Social Research.
