From recently translated letters, it appears that his wife's name is Clara and possibly that is her in the photo with him. But that is only a guess.
We also know from family stories that he suffered from depression and committed suicide; yet again we do not have documented proof.
He did serve in the German Army in World War I, and as this letter states, he was a patient in a sanatorium in Leipzig for several months.
As usual with Moritz, his life story is incomplete, and contains more questions than answers. For we do not know why he was a patient there.
Below is a postcard from Moritz to his sister Martha in Brooklyn, written in 1921. Both front and back are shown. The front appears to be a group photo that contains associates of some kind. And below the postcard is the English translation.
With much gratitude for our translator Matthias Steinke for his outstanding ability to be able to transcribe and translate what often are less than optimal handwriting specimens. Below is the English translation:
(sender): M. Braunhart, Leipzig, Roßstr. 12 I (at the moment: Bad Reiboldsgruen - in the Vogtland-area)
20 May 1921
