How to represent women?

The 7th Conference on Physics in 1933 is exceptional in terms of female presence since it features three female participants: Marie Curie, Irène Joliot-Curie and Lise Meitner. Such a proportion of women will not recur for a long time.

From 22 to 29 October 1933, 41 physicists (three of whom were women!) were invited to discuss the ‘Structure & properties of the atomic nucleus’. A real record in terms of female attendance!
