Audio Quality Characteristics of Electric Radio-France

My parents, Adolph and Gisela Razdowitz were employed at Electric Radio-France between 1934 and 1939.  It was a small company, and my father, with a PhD in Electromagnetism from Un. Vienna, was the main designer.  He told me that ERF wanted to make exceptional audio quality the hallmark of the company.  I believe that loudspeakers made by Michel Yardeny were employed in these sets.  Yardeny emigrated to New York city and built successful battery company Yardeny Electric Inc. 

I have attached a photograph which I believe may have been taken at ERF in Neuilly.  I do not know the identity of the person in the picture.  It was taken by my father.
