Question: What year did Sender Freies end in the city where the person who Landau's function is named after died?

full_context: Document 1: Lilli Jahn: Lilli Jahn was born as Lilli Schlüchterer, daughter of a wealthy tradesman who lived in Cologne as a liberal assimilated Jew. She got a quite progressive education for a girl at that time: She was taking her A-levels in 1919 at Kaiserin-Augusta-School in Cologne and started after that studying medicine in Würzburg, Halle (Saale), Freiburg im Breisgau and Cologne. Her sister Elsa who was a year younger than she was studied chemistry. 1924 Lilli finished her studies successfully and got her conferral of a doctorate with a thesis about Hematology. Firstly she worked on a temporary employment at a doctor's practice and the "Israelitischens Asyl für Kranke und Altersschwache" in Cologne.
Document 2: Joachim Prinz: At 21, Joachim Prinz received his Ph.D. in Philosophy, and had minored in Art History, at the University of Giessen. He was ordained as a rabbi at the Jewish Theological Seminary in Breslau. He married Lucie Horovitz, the daughter of the seminary's most prominent professor. She died in Berlin shortly after giving birth to their daughter Lucie. Prinz married Hilde Goldschmidt in 1932. They had three children, Michael (born in Berlin), Jonathan and Deborah (both born in the United States)
Document 3: Schur polynomial: In mathematics, Schur polynomials, named after Issai Schur, are certain symmetric polynomials in "n" variables, indexed by partitions, that generalize the elementary symmetric polynomials and the complete homogeneous symmetric polynomials. In representation theory they are the characters of polynomial irreducible representations of the general linear groups. The Schur polynomials form a linear basis for the space of all symmetric polynomials. Any product of Schur functions can be written as a linear combination of Schur polynomials with non-negative integral coefficients; the values of these coefficients is given combinatorially by the Littlewood–Richardson rule. More generally, skew Schur polynomials are associated with pairs of partitions and have similar properties to Schur polynomials.
Document 4: Prime number: are prime for any natural number n. Here  represents the floor function, i.e., largest integer not greater than the number in question. The latter formula can be shown using Bertrand's postulate (proven first by Chebyshev), which states that there always exists at least one prime number p with n < p < 2n − 2, for any natural number n > 3. However, computing A or μ requires the knowledge of infinitely many primes to begin with. Another formula is based on Wilson's theorem and generates the number 2 many times and all other primes exactly once.
Document 5: Landau's function: In mathematics, Landau's function "g"("n"), named after Edmund Landau, is defined for every natural number "n" to be the largest order of an element of the symmetric group "S". Equivalently, "g"("n") is the largest least common multiple (lcm) of any partition of "n", or the maximum number of times a permutation of "n" elements can be recursively applied to itself before it returns to its starting sequence.
Document 6: German reunification: The German reunification (German: Deutsche Wiedervereinigung) was the process in 1990 in which the German Democratic Republic (GDR / DDR / East Germany) joined the Federal Republic of Germany (FRG / West Germany) to form the reunited nation of Germany, and when Berlin reunited into a single city, as provided by its then Grundgesetz constitution Article 23. The end of the unification process is officially referred to as German unity (German: Deutsche Einheit), celebrated on 3 October (German Unity Day) (German: Tag der deutschen Einheit). Following German reunification, Berlin was once again designated as the capital of united Germany.
Document 7: Siegfried Landau: He was born in Berlin, the son of Ezekiel Landau, an Orthodox rabbi, and Helen (Grynberg) Landau. He was a music student at the Stern and Klindworth-Scharwenka Conservatories in Germany. His family emigrated to London in 1939. In 1940, Landau came to New York City and was a pupil of Pierre Monteux. In 1943, he became a faculty member of the New York College of Music (after 1968 absorbed into New York University's Steinhardt School of Culture, Education and Human Development).
Document 8: Ostdeutscher Rundfunk Brandenburg: Ostdeutscher Rundfunk Brandenburg (ORB – "East German Broadcasting Brandenburg"), based in Potsdam, was the public broadcaster for the German federal state of Brandenburg from 12 October 1991 until 30 April 2003. It was a member organization of the consortium of public-law broadcasting organizations in Germany, ARD.
Document 9: John von Neumann: Additionally, "[I]n the general case, von Neumann proved the following basic representation theorem. Any complemented modular lattice L having a "basis" of n≥4 pairwise perspective elements, is isomorphic with the lattice ℛ(R) of all principal right-ideals of a suitable regular ring R. This conclusion is the culmination of 140 pages of brilliant and incisive algebra involving entirely novel axioms. Anyone wishing to get an unforgettable impression of the razor edge of von Neumann's mind, need merely try to pursue this chain of exact reasoning for himself—realizing that often five pages of it were written down before breakfast, seated at a living room writing-table in a bathrobe."
Document 10: Nordwestdeutscher Rundfunk: Nordwestdeutscher Rundfunk ("Northwest German Broadcasting" - NWDR) was the organization responsible for public broadcasting in the German Länder of Hamburg, Lower Saxony, Schleswig-Holstein and North Rhine-Westphalia from 22 September 1945 to 31 December 1955. Until 1954, it was also responsible for broadcasting in West Berlin. NWDR was a founder member of the consortium of public-law broadcasting institutions of the Federal Republic of Germany, the ARD.
Document 11: Ackermann function: In computability theory, the Ackermann function, named after Wilhelm Ackermann, is one of the simplest and earliest-discovered examples of a total computable function that is not primitive recursive. All primitive recursive functions are total and computable, but the Ackermann function illustrates that not all total computable functions are primitive recursive.
Document 12: Schweizer Radio DRS: On 1 January 2011, Schweizer Fernsehen (SF) and Schweizer Radio DRS began the process of merging the two entities into Schweizer Radio und Fernsehen (SRF). On 16 December 2012, the merger was complete, with SF and SR DSR adopting the SRF name to their television and radio stations.
Document 13: Edmund Landau: Edmund Landau was born to a Jewish family in Berlin. His father was Leopold Landau, a gynecologist and his mother was Johanna Jacoby. Landau studied mathematics at the University of Berlin, receiving his doctorate in 1899 and his habilitation (the post-doctoral qualification required in German universities) in 1901. His doctoral thesis was 14 pages long.
Document 14: Sender Freies Berlin: Sender Freies Berlin (SFB) () was the ARD public radio and television service for West Berlin from 1 June 1954 until 1990 and for Berlin as a whole from German reunification until 30 April 2003. On 1 May 2003 it merged with Ostdeutscher Rundfunk Brandenburg to form "Rundfunk Berlin-Brandenburg".
Document 15: Enrique Loedel Palumbo: Loedel Palumbo was born in Montevideo, Uruguay and studied at the University of La Plata in Argentina. His doctoral advisor was the German physicist of Jewish origin Richard Gans. Loedel wrote his Ph.D. thesis in December 1925 on optical and electrical constants of sugar cane. An extract of the thesis was published in German in Annalen der Physik in 1926. He then began his career as professor in La Plata.
