Mabel Osterhoudt died of an enlarged heart on July 27, 1983. She is buried in Westminster Cemetery near Garden Grove, California under a blue granite marker with an MRL emblem on it. Her heart condition may explain all the one story houses they lived in.

In January 1984, Elmer was at a senior citizen's dance where he met a woman named Lois. Elmer and Lois were soon together and Lois took over some of Mabel's role at MRL.

How much energy can one guy possibly have? Five months after his wife died, at 84 years old and still working at MRL, he was at a DANCE. And he hooks up!

On December 30, 1986 Elmer wrote that he had had shingles on his left arm since December 12, so his health may have been beginning to fail. I ordered a cord for a headset, and in typical MRL fashion, Elmer wrote back that the cords now cost twice as much, so he makes his own. "Will last forever - we hope." He charged $3.75. Thirty-two  years later the cord still looks new. (It hasn't been used much.)

MRL-made headset cord, assembled by Elmer in December of 1986.
This was one of the last MRL items ever made.

On June 1, 1987. Elmer G. Osterhoudt died of injuries sustained in an automobile accident.
He had maintained Modern Radio Laboratories for 55 years.

Below is a list of addresses for MRL. It is not complete.
Notice the years 1953 to 1965 overlap with 1954 to 1956. Perhaps he had two properties.
I'll try to refine this as time goes on.

In 1924 Elmer's first radio store, The Manchester Radio Electric Shop, was located at 1909 East Nadeau Street in Los Angeles, California. He began the business with a $640 loan from his father, who was a carpenter. Elmer's father built the shop and Elmer worked there with his brother. A motel now occupies the site.

In February of 1986, the advertisement above was placed by MIDCO in the "Wanted" section of a magazine named "The Horn Speaker."
Elmer placed an add in the same issue of the magazine.
In the September 1987 issue this message was printed in the "Wanted" section. It says that MIDCO was founded through Elmer's encouragement and you can write to Mel Osterhoudt for more details. I wrote to Mel. Unfortunately it was 31 years later. The unopened letter was returned with "NOT AT THIS ADDRESS" written on it.

(Note: an email from Paul Nelson informed me that his friend, Mel Osterhoudt, died in the early 1990s.)
These MIDCO ads appeared in Hands On Electronics from July 1986 till December 1988.

The August 1987 issue of Monitoring Times, page 19, states the Osterhoudt family was considering selling MRL to a qualified individual. In the early 1990s MRL reappeared under the direction of Paul Nelson. All trademarks and copyrights now belong to him.
This advertisement appeared in "The Horn Speaker" in 1998.
The MRL website appeared soon afterward.
From an article in "Radio Age" by Dick Mackiewicz: "Elmer was involved in a severe automobile accident in 1986 and never recovered. Paul visited Elmer during his convalescence and expressed interest in carrying on Elmer's business. Elmer and his family liked Paul a great deal, and when Elmer passed away in 1987, Paul bought Elmer's business and moved it to it's present location in Minnesota."

Now if we could only figure out who that other Elmer kid was, the one who showed up at the Osterhoudt place in 1915 (Page 1) and helped get the radio working and this whole thing started, hoopie-hellie, that would really be something.


Almost all of the personal information presented here about Elmer G. Osterhoudt came from Elmer Osterhoudt himself...
... except this: Ready?

Wait for it...

                                                               His middle name was Guy!

* When the Osterhoudts purchased this location in 1938, the average cost of a house in California was $3,527. They
   must have owned the whole building. (See picture on the bottom of page 4.) No one else on the census page has a
   house valued at this much.

There is nothing written by Elmer that references Mabel ever working for a railroad.

*** Only one other person on the census page made this much money; he was a chemist in a paint factory.

I would like to extend a sincere "thank you" to Don Knotts of Hillsboro, Oregon for sending me the unassembled kits, coils and documents that were passed down to him by his father. 

Thanks also to tack, Peter Bertini, Number 6, mrx, wazz, Bugman, and radiohenry of the Antique Radio Forum.
Another thanks to Gary B. Schneider who somehow, some way, still has MRL coils available on his website.
Oh yeah, thanks to Scott of "Scotts Crystal Radios," who doesn't know I stole his picture of the MRL No. 2
Crystal Set. He's where you get your headphones for your crystal radios. His website is here.

Thank you also to our Australian friend Graeme Zimmer, who provided the list of MRL publications shown on Page 6 and the photos of the MRL Carborundum crystal.

Thanks also to AmericanRadioHistory.com.

Thanks to Paul Nelson for keeping MRL alive into the 21st Century.
