 From 1942 to 1949 Hale worked as Editorial Associate for "Art News" magazine.A long-time Instructor of Drawing and Lecturer on Anatomy at the Art Students League, and Adjunct Professor of Drawing at Columbia, Hale taught and wrote on the principles of chiaroscuro and observation from life, encouraging his students to see and draw forms in nature as the geometric "mass conceptions" of cylinders, cubes, or spheres.His lectures at the League included demonstrations of life-size figure drawings, much as had those of his teacher and predecessor, George Brandt Bridgman.
