by Oscar Chrisman
Oscar Chrisman (1855–1929) was an American educator and author whose name is most often linked to early thinking about the systematic study of children. Contemporary library and public-domain records identify him as the author of Paidology; The Science of the Child. The Historical Child, published in 1920.
His writing looks at childhood through history and across cultures rather than treating it as a purely private or domestic subject. That broad approach is a big part of why he is still remembered: later references to his work often connect him with early efforts to define a more holistic field for studying child life.
Although detailed biographical information is limited in the sources I could confirm, his surviving work suggests a scholar interested in education, social customs, and the place of children in civilization. Readers coming to him now will mostly know him through The Historical Child, which remains available through major library and public-domain archives.
