The digital version of the Kriegstagebuch Fridolin Mayer is an initiative of the Erzbischöfliches Archiv, Freiburg im Breisgau. Mayer (1877-1956) was a Catholic priest who served as a volunteer at several front locations in France. In 1918 he served briefly as a chaplain for prisoners of war in Switzerland. The archdiocesan archive at Freiburg holds the original manuscript (EAF Ha 595) and a typescript made in 1927 (EAF Na 16/1). The diary entries are published in blog fashion in chronological order. For each day of the diary a post will be created. The digital version is only accessible in German.
