Robert was born about 1842.
Robert migrated to America around 1864, about a year or so after his older brother, Adolph. Initially, Robert lived in New York with Adolph.
Robert, together with a younger brother Edmund, who had followed from Germany a few months later, moved to San Francisco in August, 1870.
Robert was a cigar-maker by trade but, within a matter of months, both Robert and Edmund were indicted by a US Grand Jury on charges of "impairing and lightening gold coins of the United States".
Robert's trial was reported extensively in the "Daily Alta California" Newspaper in December, 1870 and, in the newspaper reports, Robert's Defense Counsel (Mr Porter) was commended for his zeal, stating that, "...in his summing up...the able counsel showed that black was white, and yellow a brilliant crimson..." 
Nevertheless, the jury retired for one hour and then returned a verdict of "Guilty".
