Beyond wings, this has specifically to do with an "auxiliary" lift system, pertinent to airplanes operating at low speed. Within the area of lift, and perhaps that of airplane navigation, Esnault-Pelterie stands out as one of our most precisely trackable inventors. From the diagrams here, he seems to have been highly attentive to aerodynamics.
