In a follow-up to her review of Motherhood, the Elephant in the Laboratory: Women scientists speak out by Emily Monosson, Alison George decided to investigate how many women who won Nobels also did the motherhood thing:
I started at the first Nobel prize awarded to a woman: Marie Curie, in 1903. To my surprise, she had 2 children (as well as 2 Nobel prizes). Her daughter, Irene, only managed one prize in 1935, but also produced two offspring. And so it went on. Gerty Cori (Nobel prize for in physiology or medicine 1947, 1 kid), Maria Geoppert-Mayer (Nobel prize for physics in 1963, 2 kids) Dorothy Crowfoot Hodgkin (Nobel prize for chemistry in 1964, 3 kids), Rosalyn Yolow (Nobel prize for physiology or medicine in 1977, 2 kids – Yolow writes in her Nobel autobiography that they had sleep-in help until their youngest child was nine – thanks for the tip!)
After this, something strange seems to happen. Five women were awarded Nobel prizes in the 1980s, 1990s and in 2004, but there is no mention of children in their Nobel biographies. Did these women have kids and just not mention it? Or didn’t they have any? Further research revealed that three certainly didn’t have children, but I still don’t know the answer for the other two (and, frankly, it’s none of my business).
Of course, we’re dealing with small numbers here, but this does look like a trend. I don’t know what underlying forces might be responsible, but here are some hypotheses that might be worth investigating:
