Alexander Romanovich Luria was a Soviet neuropsychologist, often credited as the father of modern neuropsychology. He developed an extensive and original battery of neuropsychological tests during his clinical work with brain-injured victims of World War II, which are still used in various forms. He made an in-depth analysis of the functioning of various brain regions and the integrative processes of the brain in general. Luria's magnum opus, Higher Cortical Functions in Man (1962), is a much-used psychological textbook which has been translated into many languages and which he supplemented with The Working Brain in 1973.
