1. Ask a Librarian: Magnavox Loudspeaker. The Napa County Historical Society Answers the Question, "Just what is the Magnavox Loudspeaker anyway?"; on the beginnings: ...The first time Edwin Pridham and Peter Jensen tested the loudspeaker, they triggered a deafeningly loud shriek and a crack that sounded like gunfire – what is now called “feedback” and is caused by having the microphone and speaker too close together. The subsequent tests went much better. Jensen and Carl Albertus, one of their lab assistants, ran all over town waving their arms to let those back at the lab know when they could hear the sounds. They added a second speaker and Jensen waited at the top of Cup and Saucer Hill as Pridham spoke loudly and clearly, “Hello, Sacramento, hello, Sacramento. Can you hear me? How is my voice coming in? Do you hear me clearly and distinctly? Hello, Sacramento. If you can hear me, start your bonfire.” Napans all over heard the mysterious voice booming from the heavens, and it wasn’t long before locals were calling the house requesting music. Note that Napa to Sacramento is actually more than 50 miles, as the crow flies (or 60 miles as the crow drives). (Submitted on December 7, 2015.)
