I don't know. This seemed like a pretty successful enterprise. Of course, the boss, Harlow Shapely was a man, but he looked out for his ladies. The woman may have been grateful to have the opportunity to work a jobs they loved, but they were never given the respect afforded their male counterparts (especially by German astronomers). Shapely wanted Annie Jump Canon to be given the title of Professor, but the President of Harvard said that Harvard would never have a woman professor. Despite the best efforts of David Hilbert, der Noether never received an academic appointment at Göttingen, either.
I think it’s unfair to judge the ability and productivity of women based on some half-assed social experiment in Sweden. My wife has worked in all-female environments that she loved, like schools and consignment shops and some she hated. When she hated places, it was because of female interpersonal dynamics, admittedly.
