Jazz Age Music reports that Ivy Benson was born on this day in 1913. Here is what the site says about her:
Ivy Benson was born in 1913, in Holbeck, a suburb of Leeds, West Yorkshire. She was a very accomplished musician on electric organ, piano, saxophone and clarinet, and led a renowned all girls band for over 40 years. The interest in music came from her father, who played various instruments in the Leeds Symphony Orchestra and other smaller ensembles as diverse as theatre pit bands and a musical comedy group “The Ten Loonies”.
I don’t know much about Benson, but it seems pretty obvious that a woman in that age who became a virtuoso saxophone player and led an all-woman band was a ground breaker.
