For most of she avoided public life but did spend time in England with her friend and fellow physicist, Hertha Ayrton.
She returned to her laboratory only in December, after a break of about 14 months. The Institute's development was interrupted by the coming war, as most researchers were drafted into the French Armyand it fully resumed its activities in She provided the radium from her own one-gram supply.
