DUBUQUE RUBBER AND BELTING COMPANY
Emil Kiene, son of Peter Kiene, Sr. and brother of Paul, entered the business when he was seventeen. He mastered all the details of the company and in 1900 bought out the interests of his brother and father and operated the business as his own. The offices and warehouse were located at 422 Main.
The 1886-87 through 1923 Dubuque City Directory continued to locate this business at 422 Main.
