Hello Martina,
I am sorry that I cannot write in German...
I found "Frank Peter Louis" (on Ancestry.com), on the World War 1
Registration Cards (12 Sept 1918).
He is living at P.O. Box 702, Coalinga, (Fresno County), California.
He is working as a Painter for S.P. Company.
He states he has no family residing in the USA.
The birthdate listed: 2 April 1879.
His physical description is:
Height: Short,
Build: Stout,
Eye color: Gray,
Hair color: Brown.
I will send you a download of the WW1 Registration card direct. If I
find anything else, I will send it to you directly also.

Hallo Marianne,
sorry, but my english is very bad !!! But I hope, you can understand
me....... 
Thank you so much for this surprise - so he has lived at 1918 !
In 1911 he has written to his family, that he want to go for search gold -
and until this time he did not write any letter to Germany.
So I think, he did not found gold........ because he works 1918 as a
painter.
But why he did not write ??? Mh......
Where can I find his death ?
I will be happy, if you find anything more about him.
Vielen, vielen Dank
