His sympathies in the Franco-German War (July 1870-May 1871) were clearly aligned with Germany. Ruhling was an assayer and banker in San Francisco, CA & Virginia City, Gold Hill and Hamilton, Nevada. He began to establish himself in San Francisco around 1858. By 1861, Ruhling was working and residing in Nevada. His business partner in 1862 was H.V.S. McCullough in the firm of Ed Ruhling & Co Bankers and Assayers in Virginia, Nevada Territory. In 1869, Ruhling operated an assay office at the new silver mining camp of Hamilton in eastern Nevada. Ruhling's business was bought out by McCullough in March, 1871. The Ruhling Assay Office was given the order for making the last (gold) spike for the transcontinental railroad- the original is located at Stanford University. Virginia City Nevada 1870
