By Henry Smith Williams, M.D., LL.D. When the discovery of radium was given to the world, together with the fact that a woman had had the principal share in that discovery, there were not wanting critics who contended that Madame Curie's achievements were due to the guidance of her husband's philosophical imagination and the inspiration of her love for him. Madame Curie's scientific activity after her husband's death silenced such critics for a time; but the recent publication of the Curie-Langevin correspondence has brought up again the question, Can a woman working independently, with no aid from outside influences, “develop the type of imagination that is essential to creative investigation in science"?
