The other response was from Hartmut Schutz, a researcher in Germany who is trying to identify all the violinists in a picture of Leopold Auer and 43 of his students taken in 1914. The picture is owned by the Dresden State Opera historic archive, so I do not have permission to reproduce it here. I poured over it, comparing the unidentified women to the picture of Stillings from a 1923 promo ad. I thought I'd found her, but Dr. Schutz thinks my choice is someone else, the Swedish violinist Greta af Sillen. A new name for me! Anyone have any information on this violinist?
