VI. First Commercial Telephone Exchange
THE first commercial telephone exchange system in the world was opened in New Haven, in January, 1878, and has been in continuous operation ever since. This pioneer exchange was organized by Mr. George W.

Now in the beginning of the evolution of telephone exchanges, there was neither experience nor knowledge to guide the investor or the manager. There were no known methods of operation or of maintenance to render uniform and no equipment to standardize, because the to-be equipment had yet to be evolved from needs then unknown. The Bell company had no factory and supplied only the hand telephones, which were made to order under contract. Thus each licensee was largely thrown on his own resources and compelled to devise much of his exchange equipment and to secure from several different sources such associated apparatus as was available. Then the installation was necessarily made and the lines run with the aid of the telegraphers of that day. For in 1877-8, the only 'electricians' were the men associated with the telegraph companies. The electric light and the trolley then had no commercial existence. Thus, through the needs of the telephone exchange, was evolved that now very essential person the
