During his editorship of School Arts Magazine from 1920 through 1950, Pedro de Lemos changed the direction of US art education from European fine art masters to a more global focus. There were no conventions of art teachers K- grade 12 until 1950, so all ideas were shared via School Arts Magazine. This important work is just now starting to be studied, along with that of Arthur Wesley Dow At the Columbia University Teachers' College.
In addition, de Lemos raised the crafts to academic notice in his magazine. He was profoundly influenced by the Arts and Crafts Movement.
