Thiel
Dr. Walter Thiel (March 3, 1910 Breslau - August 18, 1943 Karlshagen near Peenemünde) was a German rocket scientist. Walter Thiel provided the decisive ideas for the A4 rocket engine and his research enabled rockets to head towards space.
Life
Walter Erich Oskar Thiel was born on March, 3, 1910 in the Silesian city of Breslau, as second son of Oskar Thiel (civil servant at the German Post) and Elsa Thiel.
1929 Walter Thiel passes all Abitur exams with the highest possible grade A. After his Abitur he studied chemistry at the Polytechnical College in Breslau. Due to his excellent work he was exempt from study fees as of the third semester. In summer semester of 1931 he passed the preliminary examination with excellence. In winter semester 1933 he passed all 7 diploma exams with the highest possible grade A and he became Dipl.-Ing. (chem.).
In 1934 his thesis “Über die Addition von Verbindungen mit stark polarer Kohlenstoff-Halogenbindung an ungesättigte Kohlen-Wasserstoffe“ received the highest possible honor (summa cum laude). He became Dr.-Ing. (chem.). His doctorate was confirmed on November 8, 1934 in Breslau (source: Walter Thiel’s doctorate).
Thiel's Professor in Breslau recommended Thiel to the Research Institute of the German army ordnance office of under-secretary Prof. Karl Erich Schumann at the University of Berlin. Thiel’s previous findings had techological applicability and therefore he was able to continue his fundamental research in a leading position. Late 1934 or early 1935 Thiel became research instructor at Reichswehrministerium. Schumann accompanied many diploma theses and dissertations, including that of Wernher von Braun, who completed his dissertation in 1934. The contacts between the testing ground in Kummersdorf and Schumann’s Institute was close, the eastern part of the site in Kummersdorf served as an experimental base for Schumann’s institutes, in the west a group of scientists around Major Walter Dornberger carried out their experiments. Here Thiel got to know Dornberger and von Braun. In autumn of 1936 Dornberger asked Thiel to move from fundamental research to Wa Prüf 11 at Kummersdorf’s western testing ground. All topics regarding the engine were assigned to Thiel, and he had to further advance the propulsion, which he managed in a very short time. In his paper “Empirische und theoretische Grundlagen zur Neuberechnung von Öfen und Versuchsdaten, Schießplatz Kummersdorf Vers. West“, that he presented on April 27, 1937, Thiel introduces developments that lead to decisive changes, including a shortening of the oven and an optimization of the injection nozzle. Furthermore, Thiel continued to research different fuel mixtures for the rocket engines.
In 1937 the first scientists moved from Kummersdorf to Peenemünde. As the test stations were not ready yet, Thiel and his team stayed in Kummersdorf until 1940. In 1940 many new scientists were recruited in order to speed up the R&D of the A4. Chemist Gerhard Heller became a very important co-worker of Thiel. They also established private contacts. Other colleagues of Thiel at the development unit, who later followed von Braun to Fort Bliss (USA) as the first 118 paperclip engineers, included: Hermann M. Bedürftig, Konrad Dannenberg, Werner Dobrick, Hans Fichtner, Werner Gengelbach, Hans J. Lindenmayr, Dr. William A. Mrazek, Kurt E. Patt, Gerhard H. Reisig, Walther J. Riedel (Riedel III), Ludwig Roth, Helmut Zoike.
The scientists’ hard and intense work on the A4 project was crowned with the first successful launch from test station VII on October 3, 1942. The rocket flew 190 km in the targeted direction and it reached a height of 85 km. The top-speed was 1,322 m/sec. As the A4 was now showing military qualities, the NS leadership was demanding immediate implementation in war. Mass production replaced science, although the whole unit was still immature. There were many launch failures after October 3, 1942.
In 1943 Thiel and many fellow scientists and researchers were very exhausted and unhappy in Peenemünde. Work overload, pressure to succeed and the changeover from a research unit to a production facility started to take its toll on the scientists. Thiel refused to declare the rocket engine ready for mass production. In a letter to von Braun, sent during a trip to a health farm, Thiel described the Aggregat 4: “…where it is more of a complicated lab product than a mass item….”. Thiel formulated his protest by handing in his resignation orally on August 17, 1943. He planned to get his professorship at a university. Dornberger rejected his resignation.
During the following night from August 17 to August 18, 1943 the Royal Air Force launched a bombing raid on Peenemünde (Operation Hydra). The Thiel family died in a slit trench in front of their home in Karlshagen, it is very likely that a bomb hit the slit trench directly. Thiel and his family (wife Martha, daughter Sigrid and son Siegfried) were buried at the war cemetery in Karlshagen.
Thiel’s accomplishments were not forgotten. In 1970 a moon crater was named after him. It is located on the dark side of the moon and it is not visible from earth. (Coordinates: 40° 42’ N / 134° 30’ W, mean diameter: 32.0 km). In addition, Thiel was one of the first pioneers to be inducted in the “Space Hall of Fame” in Alamogordo, New Mexico, USA in 1976.
