Question: In which year was this Nazi Party paramilitary rank created that Emil Ketterer belonged?
Context: Korpsführer was a Nazi Party paramilitary rank that was the highest rank used by the National Socialist Motor Corps and the National Socialist Flyers Corps.  Translated as "Corps Leader", the rank of Korpsführer was held by the single officer in command of the entire organization.  The rank was the equivalent of the "Sturmabteilung" title of "Stabschef" and at least on paper the rank of "Reichsführer-SS". Emil Ketterer (6 August 1883 – 23 December 1959) was a German track and field athlete who competed in the 1912 Summer Olympics.  Later in his life, he became an ardent Nazi and SA-Obergruppenführer.  As a medical doctor, he was involved in approval and promotion of euthanasia under the Nazi regime.  He was father-in-law of Hanns-Martin Schleyer, SS officer and victim of the Red Army Faction. The ranks and insignia of the Hitler Youth were a Nazi Party paramilitary rank system that existed from 1932 to 1945.  The Hitler Youth had existed for nearly a decade before, but the organization did not maintain any particular system of ranks.  Such ranks were introduced in the early 1930s and became widespread after the Nazi Party came to power in 1933. Mann (German for "man", "male", "husband", or "fellow"), was a paramilitary rank used by several Nazi Party paramilitary organizations between 1925 and 1945.  The rank is most often associated with the SS, and also as a rank of the SA where "Mann" was the lowest enlisted rank and was the equivalent of a private. SS-Anwärter ] is a German title which translates as “candidate” or "applicant".  During the Third Reich, "Anwärter/SS-Anwärter" was used as a paramilitary rank by both the NSDAP and the SS.  Within the Nazi Party, an "Anwärter" was someone who had been accepted into a government service position and the rank was issued in two degrees: one for party members and the other for non-party members.  "Anwärter" was the lowest Nazi Party rank in a complex and extensive system of Nazi Party political ranks leading up to such positions as "Gauleiter" and "Reichsleiter". Obergruppenführer (] , "senior group leader") was a Nazi Party paramilitary rank that was first created in 1932 as a rank of the "Sturmabteilung" (SA), and adopted by the "Schutzstaffel" (SS) one year later.  Until April 1942, it was the highest commissioned SS rank, inferior only to "Reichsführer-SS" (Heinrich Himmler or RFSS, which was the internal SS-abbreviation for Himmler) Translated as "senior group leader", the rank of "Obergruppenführer" was senior to "Gruppenführer".  A similarly named rank of "Untergruppenführer" existed in the SA from 1929 to 1930 and as a title until 1933.  In April 1942, the new rank of "SS-Oberst-Gruppenführer" was created which was above "Obergruppenführer" and below "Reichsführer-SS". A Gauleiter (] ) was the party leader of a regional branch of the NSDAP (more commonly known as the Nazi Party) or the head of a "Gau" or of a "Reichsgau".  The word can be singular or plural, depending on the context.  "Gauleiter" was the second highest Nazi Party paramilitary rank, subordinate only to the higher rank "Reichsleiter" and to the position of "Führer".  During World War II, the rank of "Gauleiter" was obtained only by direct appointment from Adolf Hitler. Oberscharführer (] , "senior squad leader") was a Nazi Party paramilitary rank that existed between 1932 and 1945.  Translated as “senior squad leader”, "Oberscharführer" was first used as a rank of the "Sturmabteilung" (SA) and was created due to an expansion of the enlisted positions required by growing SA membership in the late 1920s and early 1930s.  The SA rank of "Oberscharführer" was senior to "Scharführer" and junior to the rank of "Truppführer". Rottenführer (] , "section leader") was a Nazi Party paramilitary rank that was first created in the year 1932.  The rank of "Rottenführer" was used by several Nazi paramilitary groups, among them the "Sturmabteilung" (SA), the "Schutzstaffel" (SS) and was senior to the paramilitary rank of "Sturmmann". Truppführer (] , "troop leader") was a Nazi Party paramilitary rank that was first created in 1930 as a rank of the "Sturmabteilung" (SA).  Translated as "Troop Leader", the rank of "Truppführer" evolved from early "Freikorps" titles which traced their origins to World War I.
