Carl Fuchs
1916

This isn't actually taken at the RNCM. It was taken in the Ruhleben camp for English prisoners of war in Germany, 1916.
The story is that Carl Fuchs, a 'cello professor at the Royal Manchester College of Music (1893-1973) visited his mother in Germany in the summer of 1916. When WW1 broke out he was detained in the camp since he had a British passport.
However, since he had completed his national service in Germany in his youth, he was released after a handful of months and was able to continue his performing career but only in Germany.
Whilst he was in the camp, however, he worked together with a few fellow prisoners and founded an orchestra (as you do). This photograph was taken of the orchestra after Fuchs has left the camp and sent to him as a greeting card.
