[ARSCLIST] RCA symphonic work competition - 1929

[Paul Charosh <L78rpm@xxxxxxx>]

In 1929, RCA Victor offered a prize of $25,000 for a new symphonic  work.  
The 
prize was divided among five composers.  Copland was  one; he received $5,000 
for his submission.  

How to find out  who were the other four recipients?  Also, who at RCA/Victor 
was in  charge of the competition?  Can one find out who were the judges?  
Can  
one find out who submitted works?
