My grandfather, Paul Helmuth Droemer, had a friend named Eduard Graff. They worked together in The Dutch East Indies in the 1930's. I'm not sure if the double "f" makes a difference or not but both men were Germans, I believe. My grandfather was for sure. I have a few photos of Mr. Graff. If you have any interest, please email me at norwoodcj@aol.com. Thanks, Carol
