As the label indicates, this is the official portrait of the
Chicago Symphony in 1947. Dad is the first face to the right of the
man standing on the right, which I assume is assistant conductor
Tauno Hannikainen, with whom I am unfamiliar.
There is a listing attached to the back of this photograph in
the album that lists the names of all orchestra personnel. As I
scanned the list I found names of quite a few persons I met or
at least knew by name over the years.
