Lewiston Mayor D.K. Worden, right, gets a briefing on the Pacific Telephone & Telegraph Co.’s new direct dial system just before the changeover at 11:49 p.m. Nov. 1 in this Al Munson photo published in the Nov. 2, 1952, Lewiston Tribune. Speaking with the mayor are George Dean, center, of PTT in Seattle, and J.W. Krauss, left, the Lewiston exchange manager. Years of preparation had preceded the switchover from manually-operated switchboards to customer-dialed phones and included telephone directories distributed by special messenger, the removal of manually operated switchboards and education of telephone users. The project cost nearly $1.6 million.
