Roger Caillois was a French intellectual, born in 1913, known for his work in sociology, anthropology, and literature. He contributed significantly to the study of games and play, exploring how they reflect cultural values. His book, Man, Play and Games, examines the role of play in society and categorizes games into different types based on their characteristics. Caillois was also involved in the Surrealist movement and later became a member of the Collège de Sociologie. His ideas on the relationship between play and culture have influenced various fields, including psychology and cultural studies, making him a notable figure in 20th-century thought.
