Patty Smith Hill

Patty Smith Hill (March 27, 1868 to May 25, 1946) was an American teacher and composer. She worked as a nursery school and kindergarten teacher and was a key founder of the National Association for Nursery Education, which now exists as the National Association for the Education of Young Children. She is perhaps best known outside education for co-writing, with her sister Mildred Hill, the tune that later became popular as Happy Birthday to You. In the atlas she matters as a builder of early childhood education as an organized profession, since the association she helped found continues today as a major body for the education of young children.
