Description
"Botched double-spread of pp. 70-71." This photograph was featured in Jane Morgan's book "Electronics in the West" with the caption: "At the San Diego Stadium on September 19, 1919, President Woodrow Wilson addressed the largest audience any speaker had ever reached, 50,000. This first successful public address system was built by E. S. Pridham and Peter Jensen, using their invention, the Maganavox loudspeaker. Two transmitting horns, suspended over Wilson's head, were connected to the amplifier and then to two Magnavox speakers mounted on top of the enclosed building."
