Here is a link to scans I made of an article from the New York Times dated Sunday March 9,1952. 

https://1drv.ms/f/s!Ak74tjL5BDQWqWP-4Kf6xejcXk1q 

The article is about changes in recording technology over the years and includes photos of two acoustic recording sessions (one with Nellie Melba and one with a small unidentified ensemble) There are also photos of Fritz Reiner and Sir Thomas Beecham recording in the "modern" style, and a sidebar where Reiner talks about the challenges of recording.
Perhaps there are better copies in the NYT archive?

 Could someone please advise me if during the
 20's and 30's 78 recording
 sessions, was the recording equipment
 located in the same room as the
 musicians? Or, was there a separate
 "control room"? I am specifically
 interested in the Decca studies, New
 York City as I am involved in a film
 short project and the music director
 maintains the "control room" came
 later.
 
 Thank you.
