The Superintendent of Boston Public Schools notes in the Annual Report from 1948-1949 that "In the Boston Public Elementary Schools special attention is given to the development of good posture. Last March, for example, the second week of the month was designated as 'Good Posture Week.' This excellent innovation brought great profit to the children."
