|Description:||This historic photograph depicted a number of Pennsylvania schoolgirls assembled in observance of “Child Health Day”. The original image was scanned from a glass lantern slide donated by the Minnesota Department of Health, which was at one time a part of the Carnegie Steel Co., Duquesne Works, Photo Department, and is now part of a historical collection of documents and photographs devoted to observances of Child Health Day in the United States.|
Starting May 1, 1924, “May Day,” was designated Child Health Day in the United States and its territories. Awareness of child health in America was stimulated by the plight of refugee children during World War One (1914-1918). The American Child Health Association, which started the observance, was founded in 1923 when the Child Health Organization and the American Child Hygiene Association merged.
