Wikipedia has a useful entry dealing with her life and career. Books about Beaux have appeared in recent years, so I can assume that she is gradually regaining the recognition she had during her productive years.
As the Wikipedia article notes, although she spent time in Paris in the aftermath of French Impressionism and at the time what is now called Post-Impressionism was underway, Beaux resolutely remained a representational painter. Which was almost essential, given that she earned her living in portraiture. Nevertheless, representational painting suited her temperament, so commerce and personality were in synch.
