Marr, David Courtenay (1945–1980)

English psychologist who developed computer-based models of the visual system. Drawing on neurophysiology and the psychology of vision, he applied his models to a number of issues, notably the problem of how objects in the perceptual field are represented within the brain. His findings are summarized in Vision (1982), published posthumously.

Marr was born in Essex and studied at Cambridge. From 1975 he worked in the USA at the artificial-intelligence laboratory of the Massachusetts Institute of Technology.
