He was a pioneer in the development of rigorous systematic mathematical analyses which he used for underlying the science of aerodynamics, which have come to form the basis of the applied science of aeronautical engineering . In the 1920s he developed the mathematical basis for the fundamental principles of subsonic aerodynamics in particular; and in general up to and including transonic velocities . His studies identified the boundary layer, thin - airfoils, and lifting - line theories . The Prandtl number was named after him . </P> <P> Prandtl was born in Freising, near Munich, in 1875 . His mother suffered from a lengthy illness and, as a result, Ludwig spent more time with his father, a professor of engineering . His father also encouraged him to observe nature and think about his observations . </P> <P> He entered the Technische Hochschule Munich in 1894 and graduated with a Ph. D. under guidance of Professor August Foeppl in six years . His work at Munich had been in solid mechanics, and his first job was as an engineer designing factory equipment . There, he entered the field of fluid mechanics where he had to design a suction device . After carrying out some experiments, he came up with a new device that worked well and used less power than the one it replaced . </P>
