Austro-Hungarian-born German physicist and engineer Hermann Oberth is regarded as one of the founding fathers of astronautics and rocketry along with Konstantin Tsiolkovsky, Robert Esnault-Pelterie, and Robert Goddard. His classic book The Rocket into Planetary Space gained him widespread attention. Oberth garnered a patent for his rocket design and launched his first rocket near Berlin, Germany, on May 7, 1931.
