New for June 2023. The National Electronics Museum (NEM) was founded in 1980 and was until recently located in Linthicum MD, close to the BWI airport. In 2023 they moved northward to 338 Clubhouse Rd, Hunt Valley, MD 21031. They are still in the process of setting up the materials.
The permanent exhibits start with Morse's telegraph and Bell's telephone, then Marconi's wireless, broadcast radio, WWII, Cold War and modern radar and electronic warfare.
It is no coincidence that much of NEM's materials bear the Westinghouse name. Westinghouse (now Northrop Grumman) was the biggest defense contractor in the Baltimore area for decades. The museum was a vision of a Westinghouse employee, Robert Dwight, dating back to a Family Day event in 1973. By 1980 a permanent museum was established.
If you attend the International Microwave Symposium and visit the Historical Exhibit, you should appreciate that much of the display comes from the NEM's collection and is shipped to the venue. each year.
Here's a video on the electronics exhibit, filmed in 2022.
