Abstract
Max Planck's place in the history of theAnnalen der Physik, which spans some two hundred years, can be characterized as unique. Planck not only published the majority of his own scientific papers in this periodical but was also connected to it personally in various editorial positions. Thus for over half a century, from 1894 until 1947, he contributed decisively toward its promotion as a leading international professional journal of modern physics. This paper documents Planck's diverse relationships with theAnnalen der Physikand analyzes his editorship against the backdrop of the evolving physics in the first quarter of the 20th century.
