Lev Vygotsky

Lev Vygotsky was a Soviet psychologist whose theory of social and cultural development reshaped the study of learning. Born in 1896 in Orsha in the Russian Empire, now Belarus, he grew up in Gomel in a Jewish merchant family and won admission to Moscow University in 1913 under the quota for Jewish students, where he studied law alongside literature, philosophy, and psychology.

After the 1917 revolution he taught literature in Gomel and ran a small psychological laboratory before being invited to Moscow in 1924 by Konstantin Kornilov to join the Institute of Experimental Psychology. Over the next decade Vygotsky and his colleagues Alexander Luria and Alexei Leontiev developed what became known as the cultural-historical school, arguing that higher mental functions arise through internalisation of social interaction mediated by signs, above all language.

His most cited concept, the zone of proximal development, defined the gap between what a child can do alone and what the child can do with adult or peer guidance, and it has guided generations of educational research. He also worked on defectology, the study of children with disabilities, and on the psychology of art, his unfinished doctoral subject.

Vygotsky died of tuberculosis in 1934 at thirty-seven. His writings were suppressed in the Soviet Union under Stalinist criticism of pedology, and his major book Thought and Language appeared in English only in 1962, after which his ideas spread widely in education and developmental psychology.

The name Lev comes from the Slavic word for lion, used as a Russian and Hebrew given name. He bore it as a masculine name common in Russian and Eastern European Jewish families.
