“I Remember Distinctly”
The two ladies above are listening to the FIRST factory-built radio made for entertainment: a 1921 Westinghouse. Did you know that radios initially required headphones?
A year prior, in 1920, Dr. Frank Conrad, while experimenting in a Pittsburgh barn, discovered that wireless enthusiasts enjoyed listening to the phonograph records that he put on the air, and the rest…is history! Except that we need the actual history to understand.
If he put music on “the air,” did that mean radio stations weren’t already playing music? Well, let’s ask Wikipedia. Conrad began work at Westinghouse Electrical & Manufacturing at 16 in 1900. At 23, he moved up to their test department, where he invented the circular-type watt-hour meter, over 30 million of which were in use by 1937. He would eventually be awarded over 200 patents throughout his life. But it was in 1916 that he installed a radio station in a two-story garage. It used a spark-transmitter, which could only be used to transmit Morse code. So no music.
When the US entered WWI in 1917, all civilian radio stations were silenced. But Conrad, working for Westinghouse, spent his time developing radio technology, using vacuum-tube transmitters, and inventing a wind-driven generator. Two years later, when the radio ban was lifted in October, he resumed his experimental station and was able to entertain other local amateurs by playing phonograph records.
As interest grew, he adopted a schedule of music. In 1920, Pittsburgh’s own Joseph Horne Dept Store began selling radios, aka “wireless receiving stations” to listen to “air concerts.” It didn’t take long for Westinghouse to construct its own broadcast station and sell receivers for this free entertainment.
The first radio station, KDKA, opened on November 2, 1920. Initially a tent on a roof, it soon became the indoor studio you see below (the tent kept insisting on blowing away). Draperies covered the ceiling and walls to prevent reverberation. A disk hanging below the upper end of the slanting bar was called “the enunciator” (which we now call a microphone). Early listeners used crystal detectors in tubeless receiving sets, but the development of the vacuum tube expanded the radio audience significantly.
Soon entertainers were asked to provide music for radio stations.
Young people especially were excited by the new technology, and competitors soon crept in. This Crosley model was advertised at $3.75.
“Oh, boy! There’s London! Last night I had Honolulu, and the night before that Porto [sic] Rico. Here’s where I get Rome. This Crosley sure does bring ’em in. There’s nothing like a Crosley.”
In 1928, Dr. Conrad received an honorary Doctor of Science degree from the University of Pittsburgh. Not until age 66 did he retire from Westinghouse, having spent his entire life in radio. He received many awards for his work, including the 1930 Edison Medal “for his contributions to radio broadcasting and short wave radio transmission,” and the 1936 Lamme Medal “for pioneering and basic developments in the fields of electric metering and protective services.” The next time you flick your radio on, pause for a moment and think of Dr. Conrad, shown below.
