In the 1890s, he left Second Christian Church and became assistant editor of the company, that published the weekly newspaper The Christian Evangelist.

In the early 1900s William Hopkins founded Standard Adding Machine Company, based on Spring Avenue, St. Louis (later became New Standard Adding Machine Company), which was the first company to release to the market a successful 10-key adding machine, launched in 1902. The Standard machine achieved a big success because it was much less expensive to manufacture and simpler to use.
