The telephone is one of mankind’s biggest inventions. In its early years, telephone operators were needed to connect a phone call. Almon Strowger, was convinced that he was losing his customers because of one of the local telephone operators. He believed that she was sending all calls to her husband who happened to be his competitor. This motivated Strowger to create the Automatic Telephone Exchange that enabled direct connection in the telephone era. No need to go through the telephone operators anymore when making phone calls!
