Hammond Museum of Radio

Posted on April 25, 2010

A set of radio communication equipment used by the military.

For the 2010 edition of Guelph's Door Open, 9 buildings were open to the public. One of them was Hammond Museum of Radio, which exhibits more than 2,000 radios developed in the past 100 years.

A balance sheet for Hammond Manufacturing, then known as O.S. Hammond & Son, circa 1925.

An assorted array of vacuum tubes used in early radios.

Telegraphs.

According to the guide, this Quaker Oats radio, originally a marketing gimmick to promote its line of confectionary goods, is responsible for making radio available for mass consumption.

One of the first plastic radios. Once an exotic item because plastic molding were not well developed at that time. They would easily crack when being extracted from the molds, and they were sensitive to temperature and humidity changes. Early designers mixed in some paint to create swirly duotones.

The AR1154 transmitter, used during W.W.II in the British built Lancaster bomber.

One of the early phonographs created by Edison. After over a hundred years, it still works. "Which of the devices you have now will last more than a hundred years?" The guide asked mockingly.
