Gray History of Wireless Museum

This exhibit is made up of over a thousand items.  You will learn about the development of radio and of the very earliest experiments of Marconi, Hertz,  Faraday and others.

You can start your visit at the newly designed timeline display that gives a visual overview of the history of wireless communications from its genesis up to today. The strength of the museum's exhibit, however, is the unique collection of very early wireless devices like “spark gap” transmitters of the early 1900s.


The founder and namesake of the Gray Museum was G. J. "Jack" Gray, W8JDV of Mason, Ohio. Jack was born in 1900 in Middletown, Ohio, on the banks of the Great Miami River. He was only twelve when he first became interested in wireless telegraphy. It was the start of a life-long affair with all things wireless. 

 This brief video tribute was presented at the 140th anniversary gathering for Dodge’s Institute of Telegraphy, Valparaiso, Indiana. The founder and namesake of the Gray Museum of Wireless was G. J. "Jack" Gray (1900-1970), W8JDV, 8ARP and 8CCP.
