"According to legend, Almon Strowger, an undertaker, was motivated to invent an automatic telephone exchange after having difficulties with the local telephone operators, where the wife of a competitor was one of them. He was said to be convinced that she, as one of the manual telephone exchange operators was sending calls “to the undertaker” to her husband, who ran a competing undertaker business."
