Foreign Office in the 1970s, and a younger brother, Magnus von Braun, who was a rocket scientist and later a senior executive with Chrysler. The family moved to Berlin, Brandenburg, in 1915, where his father worked at the Ministry of the Interior. After Wernher's Confirmation, his mother gave him a telescope, and he developed a passion for astronomy. Von Braun learned to play both the cello and the piano at an early age and at one time wanted to become a composer. He took lessons from the composer Paul Hindemith. The few pieces of Wernher's youthful compositions that exist are reminiscent of Hindemith's style. He could play piano pieces of Beethoven and Bach from memory. Beginning in 1925, Wernher attended a boarding school at Ettersburg Castle near Weimar, Free State of Thuringia, where he did not do well in physics and mathematics. There he acquired a copy of Die Rakete zu den Planetenräumen (1923, By Rocket into Planetary Space) by rocket pioneer Hermann Oberth. In 1928, his parents moved him to the Hermann-Lietz-Internat (also a residential school) on the East Frisian North Sea island of Spiekeroog. Space travel had always fascinated Wernher, and from then on he applied himself to physics and mathematics to pursue his interest in rocket engineering. The world's first large-scale experimental rocket program was Opel RAK under the leadership of Fritz von Opel and Max Valier during the late 1920s leading to the first manned rocket cars and rocket planes, which paved the way for the Nazi era V2 program and US and Soviet activities from 1950 onwards.The Opel RAK program and the spectacular public demonstrations of ground and air vehicles drew large crowds, as well as caused global public excitement as so-called "Rocket Rumble" and had a large long-lasting impact on later spaceflight pioneers, in particular on Wernher von Braun. Sixteen year old Wernher was so enthusiastic about the public Opel RAK demonstrations, that he constructed his own homemade rocket car, nearly killing himself in the process and causing a major disruption in a crowded street by detonating the toy wagon to which he had attached fireworks. He was taken into custody by the local police until his father came to get him. The Great Depression put an end to the Opel RAK program and Fritz von Opel left Germany in 1930, emigrating first to the US, later to France and Switzerland. After the break-up
