A surprising number of today's to-day's living conveniences and necessities can be traced to either inventions or developments develop-ments of the Bell System. It all started with Alexander Graham Bell's "electric speaking speak-ing telephone" in 1875. Bell's apparatus included important advancements in the speaker and microphone, which later became key elements in the development de-velopment of radio. Radio, however, didn't get very far until Harold Arnold, a Western Electric scientist, got hold of Lee DePorest's crude audion tube in 1912 and developed the modern vacuum tube. The vacuum tube is now being replaced by the transistor, transis-tor, another Bell Laboratories invention. Radio didn't mean much to the average homeowner until Western Electric, set up the first experimental radio station in 1919. This started the ball rolling for commercial broadcasting. Thomas Edison invented the movies, but the Bell System invented the first commercially successful "talkie." Henry C. Harrison, a Bell Labs engineer, designed the Vitaphone. It was a system designed to synchronize synchron-ize phonograph records with the movie reel and was used in the first sound motion pic- |
