History of maker
In 1890, Walter J. Dudley and Walter K. Menns began work on a battery powered clock in John Stark’s shop in Waltham, MA. The pair convinced a group of Natick, MA investors to form Waltham Electric Clock Company in New Hampshire in June, 1890. A factory was established in Natick and the first clock sold in early 1891. In April 1891 a group of Waltham-area investors took over the company and moved it back to Waltham.
