Alfred Adler has had a profound effect on such later theorists as Harry Stack Sullivan, Karen Horney, Julian Rotter, Abraham H. Maslow, Carl Rogers, Albert Ellis, Rollo May, and others
He did not establish a tightly run organization to perpetuate his theories
He was not a particularly gifted writer, and most of his books were compiled by a series of editors using Adler's scattered lectures
Many of his views were incorporated into the works of such later theorists as Maslow, Rogers, and Ellis and thus are no longer associated with Adler's name
