Francesco Lana de Terzi (1631 in Brescia, Lombardy – 22 February 1687, in Brescia, Lombardy) was an Italian Jesuit priest, mathematician, naturalist and aeronautics pioneer. Having been professor of physics and mathematics at Brescia, he first sketched the concept for a vacuum airship and has been referred to as the Father of Aeronautics for his pioneering efforts, turning the aeronautics field into a science by establishing "a theory of aerial navigation verified by mathematical accuracy". He also developed the idea that developed into Braille.[1]
