"The first Waldorf school opened in 1919 in Stuttgart, Germany. Emil Molt, director of the Waldorf Astoria cigarette factory, invited Rudolf Steiner to become the pedagogical director of a school for the children of his factory workers. Steiner’s insightful philosophy, that education must be based on an understanding of human development, became what we now know as Waldorf Education." source
