Here are two links to the wonderfully inspiring story of violinist, conductor and remarkable woman Ethel Stark , who organized and conducted the Montreal Women's Symphony Orchestra in the 1940s. She was a true feminist, and creative visionary in my opinion, and I'm certain she probably did not consider herself to be, however I'm sure few would disagree.
Ethel Stark lived to be 101 and passed away in Feb 2012.
