Aleksei Leontiev
Soviet Russian developmental psychologist and philosopher, founder of activity theory.
Aleksei Nikolayevich Leontiev (1903–1979) was a Soviet Russian psychologist and philosopher who helped create activity theory. He was born and died in Moscow.
Leontiev’s career was tied to Moscow State University. He started studying there in 1921, in the historical-philological faculty, which then included a philosophy department where Georgy Chelpanov taught psychology. Leontiev graduated in 1924 from what had become the Faculty of Social Sciences. From 1924 to 1930, he worked with Lev Vygotsky and Alexander Luria, developing a Marxist psychology as an alternative to behaviorism and stimulus-response explanations. In 1931, Leontiev left Moscow for a post in Kharkiv. He kept collaborating with Vygotsky for a while, but eventually they split, though they stayed in touch about scientific matters. Leontiev returned to Moscow in 1934. Later, he became head of the psychology department in the philosophy faculty at Moscow State University. In 1966, he was appointed the first dean of the university’s new Faculty of Psychology, where he remained until his death.
Leontiev’s early research, within Vygotsky’s cultural-historical framework, focused on cultural mediation. A key example is his 1931 study on mediated memory in children and adults. His own school of thought centered on a psychological analysis of activity. In the 1930s, the Kharkiv group he led—including Zaporozhets, Galperin, Zinchenko, Bozhovich, and others—began systematically developing activity theory. After moving back to Moscow and joining Moscow State University, Leontiev expanded and institutionalized this theory as the leading Soviet psychological doctrine in the postwar period.
For Leontiev, “activity” meant the processes that realize a person’s actual life in the objective world and their social existence. He proposed that human processes can be examined through three interrelated units: activity and its driving motives, actions and their goals, and operations that serve as means to achieve those goals.

Lore & Background
Aleksei Leontiev began his studies in 1921 at the historical-philological faculty of Lomonosov Moscow State University, which at the time included a Department of Philosophy where Georgy Chelpanov was teaching psychology. Leontiev studied psychology with him. In 1924, Leontiev graduated from what became the Faculty of Social Sciences. From 1924 to 1930, he worked with Lev Vygotsky and Alexander Luria, collaborating on the development of Marxist psychology as a response to behaviorism and the focus on the stimulus-response mechanism as an explanation for human behavior. Leontiev left Vygotsky's group in Moscow in 1931 to take up a position in Kharkiv. He continued to work with Vygotsky for some time but, eventually, there was a split, although they continued to communicate with one another on scientific matters (van der Veer and Valsiner, 1991). Leontiev returned to Moscow in 1934.
Reader's Guide
Leontiev's early scientific work was done in the framework of Vygotsky's cultural-historical research program and focused on the exploration of the phenomenon of cultural mediation. Representative of this period is Leontiev's study on mediated memory in children and adults, 'The development of higher forms of memory', 1931. Systematic development of the psychological foundations of activity theory was started in the 1930s by the Kharkiv group of psychologists headed by Leontiev, including researchers such as Zaporozhets, Galperin, Zinchenko, Bozhovich, Asnin, Lukov, etc. In its fullest form, activity theory was subsequently developed and institutionalized as the leading psychological doctrine in the Soviet Union in the post-war period after Leontiev had moved to Moscow and took a position at the Moscow State University. Later, he became the Head of the Psychology Department at the Faculty of Philosophy of Moscow State University. In 1966, Leontiev became the first ever Dean of the newly established Faculty of Psychology at the Moscow State University, where he worked until his death in 1979. For Leontiev, the psychological 'activity' consisted of those processes 'that realize a person's actual life in the objective world by which he is surrounded, his social being in all the richness and variety of its forms' (Leontiev 1977). The core of his work is the proposal that we can examine human processes from the perspective of their psychological macrostructure in three interrelated units: the stimulating unit of activity and motives, the behavior-orientation unit of actions and goals, and the conditional unit of operations that serve as means for the achievement of action goals.
