The importance of "Annalen der Physik" unquestionably peaked in 1905 with Albert Einstein's Annus Mirabilis papers. In the 1920s, the journal lost ground to the concurrent "Zeitschrift für Physik". With the 1933 emigration wave, German-language journals lost many of their best authors. During Nazi Germany, it was considered to represent "the more conservative elements within the German physics community", alongside "Physikalische Zeitschrift". From 1944–1946 publication was interrupted because of World War II, but resumed in 1947 under Soviet occupation rule. While "Zeitschrift für Physik" moved to Western Germany, "Annalen der Physik" served physicists in East Germany. After the German reunification, the journal was acquired by Wiley-VCH.
