Onkel Hayn was involved with several import businesses during his lifetime, all of them in different countries, and all but one of them connected in some way to his grandfather, J.H. Hofmann, Jr.. The businesses were lucrative, and Onkel Hayn states that he was worth several million DM at the peak of his career. Had it not been for WWI he would most likely have lived out his days in Le Havre, France, but both his business and home were confiscated, circumstances which eventually led to his decision to move to Switzerland.
