In 1940 Stewart graduated from
Caltech with a Ph.D. in aeronautics. In 1938, two years before earning his Ph.D., he became a Caltech faculty member. He taught aeronautics and meteorology, for many years dividing his time between teaching at Caltech and research at the Jet Propulsion Laboratory (JPL).

He also conducted research in wind-driven energy, using his knowledge of fluid flow to construct with von Kármán a turbine known as "Grandpa's Knob." Built in the mountains of
Vermont in the late 1930s, the machine generated up to a megawatt of power and operated through World War II in cooperation
