Short answers, pulled from the story.
The first three issues of Zeitschrift für Physik appeared in 1920 as a supplement to the Verhandlungen der Deutschen Physikalischen Gesellschaft. Springer Berlin Heidelberg established this new series that year to serve German physicists seeking a dedicated venue for their work.
Zeitschrift für Physik divided into parts A and B in 1975 to accommodate expanding research areas. Part C emerged in 1979 as Particles and Fields while part B evolved from Condensed Matter and Quanta to simply Condensed Matter by 1980, and part A further split into Zeitschrift für Physik A: Atomic Nuclei and Zeitschrift für Physik D: Atoms, Molecules and Clusters in 1986.
Werner Heisenberg published his paper Über quantentheoretische Umdeutung kinematischer und mechanischer Beziehungen in Zeitschrift für Physik in 1925. Max Born and Pascual Jordan submitted their joint paper Zur Quantenmechanik to the same journal that autumn, establishing matrix formulation of quantum mechanics as foundational texts for modern theoretical physics.
The original subtitle of Zeitschrift für Physik B read Condensed Matter and Quanta before changing to just Condensed Matter in 1980. Physics of Condensed Matter itself continued from a prior publication called Physik der Kondensierten Materie.
All four parts of Zeitschrift für Physik ceased independent publication when they merged into the new European Physical Journal series in 1997. Part A continues today as the European Physical Journal A while part B joined with Journal de Physique I to form European Physical Journal B, part C evolved into the European Physical Journal C, and part D merged with Journal de Physique II to create European Physical Journal D.
