In the week leading up to our celebration of International Women's Day, a series of The Essay celebrating five women who have been unacknowledged movers and shakers in the world of classical music down the ages. Each of these women overcame societal expectations or personal adversity to have real influence on the music of their day, and subsequently ours.
Betty Freeman was possibly the most influential patron of twentieth century classical music. From 1964 onwards, she gave a total of 413 grants and commissions for living expenses, compositions, recordings, performances and librettos to 81 artists. These include John Cage, Steve Reich, Robert Wilson and Peter Sellars and also younger composers such as Olga Neuwirth and Hans Peter Kyburz.
An editor of BBC Music Magazine, Helen Wallace looks for the woman behind the list of names and discovers what drove her to play so formative a role in the lives of these great musicians.
