Autopilot reducing the pilot's workload. Lawrence Sperry (the son of famous inventor Elmer Sperry) demonstrated it in 1914 at an aviation safety contest held in Paris. At the contest, Sperry demonstrated the credibility of the invention by flying the aircraft with his hands away from the controls and visible to onlookers of the contest. Elmer Sperry Jr., the son of Lawrence Sperry, and Capt Shiras continued work after the war on the same autopilot, and in 1930 they tested a more compact and reliable autopilot which kept a US Army Air Corps aircraft on a true heading and altitude for three
Pauline Sperry Under the guidance of Ernest Julius Wilczynski, her doctoral thesis, "Properties of a certain projectively defined two-parameter family of curves on a general surface", drew on his work as the founder of the American school of projective differential geometry. She earned her PhD in mathematics and astronomy in 1916 and was elected to the Sigma Xi honor society. After a year teaching again at Smith, Sperry spent the rest of her academic career at the University of California at Berkeley, beginning in 1917. In 1923, she became the first female assistant professor in the mathematics department at the university. Her
