Celebrating the Space Travel – Hermann Oberth

The Rocket City Astronomical Association put out the first edition of the locally edited Space Journal a magazine dealing with space travel and astroscience.

Do you know the space conqueror Hermann Oberth???

Quite possible  that you do not remember this name, but he is important as in science and he is placed between the American Robert Goddard and the Russian Konstantin Tiolkovski.

These three persons are the founders of the rocket science. They never collaborated, in an active way, but their conclusions are almost identically, even if their researching were performed in an independent way.

Early life

Oberth was born to a Transylvanian Saxon family in Nagyszeben (German: Hermannstadt, today SibiuRomania), Austria-Hungary.By his own account and that of many others, around the age of 11 years old, Oberth became fascinated with the field in which he was to make his mark through reading the writings of Jules Verne, especially From the Earth to the Moon andAround the Moon, re-reading them to the point of memorization. Influenced by Verne’s books and ideas, Oberth constructed his first model rocket as a school student at the age of 14. In his youthful experiments, he arrived independently at the concept of the multistage rocket, but he lacked then the resources to pursue his idea on any but a pencil-and-paper level.

In 1912, Oberth began the study of medicine in MunichGermany, but at the outbreak of World War I, he was drafted into the Imperial German Army, assigned to an infantry battalion, and sent to the Eastern Front against Russia. In 1915, Oberth was moved into a medical unit at a hospital in Segesvár, Transylvania, in Austria-Hungary (today SighişoaraRomania). There he found the spare time to conduct a series of experiments concerning weightlessness, and later resumed his rocketry designs. By 1917, he showed how far his studies had reached so far by firing a rocket with liquid propellant in a demonstration to Hermann von Stein, the Prussian Minister of War.

On July 6, 1918, Oberth married Mathilde Hummel, with whom he had four children. Among these were a son who died as a soldier in World War II, and a daughter who also died during the war when there was an accidental explosion at a liquid oxygen plant where she was in August 1944. In 1919, Oberth once again moved to Germany, this time to study physics, initially in Munich and later in Göttingen.

In 1922, Oberth’s proposed doctoral dissertation on rocket science was rejected as “utopian”. He next had his 92-page work published privately in June 1923 as the somewhat controversial book, Die Rakete zu den Planetenräumen (“By Rocket into Planetary Space”). By 1929, Oberth had expanded this work to a 429-page book titled Wege zur Raumschiffahrt (“Ways to Spaceflight”). Oberth commented later that he made the deliberate choice not to write another doctoral dissertation. He wrote, “I refrained from writing another one, thinking to myself: Never mind, I will prove that I am able to become a greater scientist than some of you, even without the title of Doctor.”Oberth criticized the German system of education, saying “Our educational system is like an automobile which has strong rear lights, brightly illuminating the past. But looking forward, things are barely discernible.”Hermann Oberth was finally awarded his doctorate in physics with the same rocketry paper that he had written before, by the University, ClujRomania, under professor Augustin Maior, on May 23, 1923.

Oberth became a member of the Verein für Raumschiffahrt (VfR) – the “Spaceflight Society” – an amateur rocketry group that had taken great inspiration from his book, and Oberth acted as something of a mentor to the enthusiasts who joined the Society. Oberth lacked the opportunities to work or to teach at the college or university level, as did many well-educated experts in the physical sciences and engineering in the time period of the 1920s through the 1930s – with the situation becoming much worse during the worldwide Great Depression that started in 1929. Therefore, from 1924 through 1938, Oberth supported himself and his family by teaching physics andmathematics at the Stephan Ludwig Roth High School in MediaşRomania.

Rocketry and space flight

In parts of 1928 and 1929, Oberth also worked in Berlin, Germany as a scientific consultant on the first film ever to have scenes set in outer space, Frau im Mond (“The Woman in the Moon”), which was directed and produced by the great film pioneer Fritz Lang at the Universum Film AG company. This film was of enormous value in popularizing the ideas of rocketry and space exploration. One of Oberth’s main assignments was to build and launch a rocket as a publicity event just before the film’s premiere. He also designed the model of the Friede, the main rocket portrayed in the film.

On June 5, 1929, Oberth won the first (Robert Esnault-Pelterie – André-Louis Hirsch) “Rep-Hirsch Prize” of the French Astronomical Society for the encouragement of astronautics in his book Wege zur Raumschiffahrt (“Ways to Spaceflight”) that had expanded Die Rakete zu den Planetenräumen to a full-length book.

In the autumn of 1929, Oberth conducted a static firing of his first liquid-fueled rocket motor, which he named the Kegeldüse. The engine was built by Klaus Riedel in a workshop space provided by the Reich Institution of Chemical Technology, and although it lacked a cooling system, it did run briefly. He was helped in this experiment by an 18 year old student Wernher von Braun, who would later become a giant in both German and American rocket engineering from the 1940s onward, culminating with the giganticSaturn V rockets that made it possible for men to land on the Moon in 1969 and in several following years. Indeed Von Braun said of him:

Hermann Oberth was the first, who when thinking about the possibility of spaceships grabbed a slide-rule and presented mathematically analyzed concepts and designs…. I, myself, owe to him not only the guiding-star of my life, but also my first contact with the theoretical and practical aspects of rocketry and space travel. A place of honor should be reserved in the history of science and technology for his ground-breaking contributions in the field of astronautics.”

In 1938, the Oberth family left SibiuRomania, for good, to first to settle in Austria, then in Nazi Germany, then in the United States, and finally back to a free Germany. Oberth himself moved on first to the Technische Hochschule in Vienna, Austria, then the Technische Hochschule in Dresden, Germany. (A Hochschule is rather like a four-year technical institute, above a high school, but not as highly-regarded, or offering as many years of study as a university does.) Oberth moved to Peenemünde, Germany, in 1941 to work on Nazi German rocketry projects, including the V-2 rocket weapon, and in about September 1943, he was awarded the Kriegsverdienstkreuz I Klasse mit Schwertern (War Merit Cross 1st Class, with Swords) for his “outstanding, courageous behavior … during the attack” on Peenemünde by Operation Hydra, part of Operation Crossbow.[10]

Oberth later worked on solid-propellant anti-aircraft rockets at the German WASAG military organization near Wittenberg. Around the end ofWorld War II in Europe in May 1945, the Oberth family moved to the town of Feucht, near Nuremberg, Germany, which became part of theAmerican Zone of occupied Germany, and also the location of the high-level war-crimes trials of the surviving Nazi leaders. Oberth was allowed to leave Nurmberg to move to Switzerland in 1948, where he worked as an independent rocketry consultant and a writer.

In 1950, Oberth moved on to Italy, where he completed some of the work that he had begun at the WASAG organization for the new Italian Navy. In 1953, Oberth returned to Feucht, Germany, to publish his book Menschen im Weltraum (Men in Space), in which he described his ideas for space-based reflecting telescopesspace stations, electric-powered spaceships, and space suits.

During the 1950s and 1960s, Oberth offered his opinions regarding unidentified flying objects (UFOs). He was a supporter of theextraterrestrial hypothesis for the origin of the UFOs that were seen at the Earth. For example, in an article in The American Weeklymagazine of October 24, 1954, Obert stated, “It is my thesis that flying saucers are real, and that they are space ships from another solar system. I think that they possibly are manned by intelligent observers who are members of a race that may have been investigating our earth for centuries…”

Oberth eventually came to work for his former student, Wernher von Braun, who was developing space rockets for NASA in Huntsville, Alabama. (See also List of German rocket scientists in the United States). Among other things, Oberth was involved in writing the study,The Development of Space Technology in the Next Ten Years. In 1958, Oberth was back in Feucht, Germany, where he published his ideas on a lunar exploration vehicle, a “lunar catapult”, and on “muffled” helicopters and airplanes. In 1960, back in the United States again, Oberth went to work for the Convair Corporation as a technical consultant on the Atlas rocket program.

Later life

Oberth retired in 1962 at the age of 68. From 1965 to 1967 he was a member of the considered to be far right National Democratic Party. In July 1969, Oberth returned to the United States to witness the launch of the Apollo project Saturn V rocket from the Kennedy Space Centerin Florida that carried the Apollo 11 crew on the first landing mission to the Moon.

The 1973 petroleum crisis inspired Oberth to look into alternative energy sources, including a plan for a wind power station that could utilize the jet stream. However, his primary interest during his retirement years was to turn to more abstract philosophical questions. Most notable among his several books from this period is Primer For Those Who Would Govern.

Oberth returned to the United States to view the launch of STS-51J, the space Shuttle Discovery launched October 3, 1985.

Oberth died in Nuremberg, Germany, on 28 December 1989, just shortly after the fall of the Iron Curtain that had for so long divided Germany into two countries.
