Marie Curie in her laboratory
The measurement of radioactivity requires great dexterity and inventive spirit. It was made possible with an experimental advice conceived by Pierre Curie, which makes it possible to measure very small charges.
The image shows Curie in profile, facing left, seated at a wooden laboratory table.
She wears a simple, long-sleeved laboratory gown, gathered at the shoulders and waist .
Her posture is upright and attentive; one hand gently adjusts a control dial, while the other rests near a piece of scientific equipment.
