History of Mason
On June 1, 1803, a veteran from the American Revolutionary War named William Mason bought 640 acres of land. This land is now the center of Mason. In 1815, he divided the land into 16 lots and called the village "Palmyra."
In 1835, people asked the federal post office to change the town's name. The town was listed as Kirkwood, possibly by mistake. Officials learned there was another Palmyra in Ohio. So, the name was officially changed to "Mason."
In 1923, Main Street was paved. This was a big event, and the whole town celebrated. For about 125 years, Mason stayed a small farming community. In 1970, just before it became a city, fewer than 5,700 people lived there.
Voice of America Radio Tower
In 1928, a very tall radio tower was built in Mason. It was called the WLW-AM tower and stood 831 feet high. Six years later, President Franklin D. Roosevelt ordered the tower to broadcast 10 times stronger.
This new power was strong enough to send radio signals across the Atlantic Ocean. But it caused problems for local people. They could hear the radio broadcast through their bedsprings, rain gutters, and even fences!
Other radio stations complained about signal problems. So, in 1939, the power was reduced back to its original strength. The company that ran the tower tried to fight this decision, but they lost in the Supreme Court.
