October Field Trip? RCA Photo Archive in Delaware
Dan Mortensen:
Was sent this link today to the
Index to RCA Photo Archive
the introduction to which says in part:
"This collection consists of negatives, a majority of which feature sound and television equipment manufactured by RCA. These images include phonographs, radios, radio-phonograph combinations, records, speakers, amplifiers, microphones, facsimile machines, televisions, equipment involved in the transmission and reception of television and radio waves, radio equipment created for use by government agencies and motion picture equipment.
"Company historian Frederick O. Barnum III salvaged this collection from the abandoned photo lab on the 4th floor of Building 10 of the RCA Camden Plant, after the plant had been vacated and abandoned by successor company Martin Marietta Corporation in April 1993."
So it's presumably professional photos of their equipment for a variety of reasons, some of which is various kinds of P.A. gear. The index is really thorough. There's over 120,000 images altogether, but a lot of it is not something most of us would be interested in, probably.
I don't completely trust myself to recognize the relevant parts to our interests; anybody want to go through and contribute to a list of what to look for when there? I'll start the list in the next post.
And I'm going to be in NYC for a month in October, and a field trip to go through this and take pictures if possible or gather prints of the cool stuff would be enjoyable and possible. If anyone wanted to join me that would only make it more fun. We can talk about that part.

01-01 (Box 1 Folder 1): Portable Public Address
01-02: School Sound, Kansas State Stadium 1934
01-06: Commercial sound rack P.D. 32, 1935 June 6
01-25: High Powered Bathing Beach Loudspeakers installation, 1937
01-37: Horn, horizontal, 1938
02-02: Notre Dame Stadium, South Bend, Indiana, 1938
02-10: Union Terminal Los Angeles installation, 1939
02-16: MI-12754 Mobile Sound System, 1939 November 29
02-29: Ohio State Stadium Sound Installation, 1940 February 12

02-39: Battleship Arizona installation, 1940 May 9
03-03: Sound Installation Inauguration installation, 1941 February 20
There's a dozen to start it off. This will be helpful when going there to focus the searching to items of interest.
And I maybe left off some interesting things without knowing what they are ("02-42: Sound Installations, 1940 July 23", for example).
Altogether, there's 298 boxes and 30+ folders in each.
Incidentally, I'm the Chair of the Historical Track at the October AES Convention in NYC, but don't have any SR history in it this year as the very able Sound Reinforcement Track Chairs have included some of that in theirs.

Almost an overwhelming amount of photographs, a good portion of which could be thought of as "relevant"!
Box #8 seems to hold a lot of the foundational horn designs. Though some of these designs may be found on the web, photos in folders 3, 5, 6, 8, 13, 14, 15, 29, & 40 may be hard to find, and certainly informative.
Other boxes also look interesting:
Box 147
Folder 17: 20 Watt Power Amplifier M-14236, 1935 July 12
Folder 18: P.A. Amplifier, 1935 July 17
Box 150
Folder 27: MI-12188 70 Watt Amp. "-- 4288 40 ," 1950 February 8
Box 150
Folder 28, 29: 70 Watt Amp. MI-12188, 1950 March 14
Box 151, Folder 13: 70 Watt PA Amplifier, 1957
Box 289, Folder 5: Lapel microphone, 1935 April 29
Happy hunting!

This is great, thanks, Art!
Another thing to look for: since Harry F Olson (inventor of the line array, amongst MANY other fundamental principles of our work) was an RCA guy, one would think there must be a TON of pictures of his work in its various stages of development.
How to pick that out of this avalanche of information? The Search function of the index gives 27 hits to "Olson", but I can't see how to locate where those hits are other than within the most general categories.
That makes me think an email to the librarians would be in order. Email sent.
Thanks again for this list, Art.
Dan Mortensen:
Hey, I got a reply from the Library!
The question was specifically about how to find pictures specifically relevant to Harry Olson, so the reply centers on that:
"Dear Mr. Mortensen,
The Harry F. Olson Papers are part of the David Sarnoff Research Library collection (Acc. 2464) and not the Barnum Collection of RCA materials (Acc. 2069).
Here is the link to the Sarnoff inventory: < https://findingaids.hagley.org/xtf/view?docId=ead/2464_09.xml >. Do a keyword search for "Harry F. Olson" and you will see the available materials on him. There is an entire subsection of the Sarnoff papers concerning him.
"I hope this helps clarify things! Please let me know how we can further help you with your research."
It's neat this is all there and I bet it's not a coincidence.
