By good fortune, Professor Becquerel used some Uran- ium for these studies. By accident, he found this Uranium was sending forth rays that had the power to act as the X-rays,—to penetrate thick and light proof paper, and after such penetration to affect a photographic plate as the sun- light did. He found that his Uranium did this whether or not it was first exposed to sunlight; in other words that the sunlight could not in any way be said to be the cause of these rays. Uranium had been known to the world for over a hun- dred years. That it possessed this power to emit rays of this penetrating nature, was something as new asit was astonishing. For years, Uranium had been used to color glass, especially the fine glasses that made much of the specialized handiwork of the glass makers of Bohemia. Marie Sklodowski, of Poland, at this time was a student at the University of Paris doing post graduate work in physics and in chemistry under Professors Becquerel and Curie, The extent and accuracy of her training and the pre- cision and clarity of her mind and methods, won for her the professional respect and regard of her instructors. Professor Becquerel and the scientific minds of the University of Paris and of Europe were so impressed with the importance of knowing what caused the strange rays Becquere] had found in his Uranium that special work was planned to discover the secret. Of them, he could learn only that they were electrical. Marie Sklodowski was invited to undertake the study and investigation of the problem, by Professor Becquerel. She accepted and carried through to completion, what has since been described as one of the most comprehensive and conclusive scientific studies of the age. With characteristic directness, she went first to the mines from which had been taken the ore that had given the Uranium to Professor Becquerel. This was called pitchblende; and, as was known to all the laboratories of Europe, it was a combination of most of the well known metals. At these mines, this pitchblende ore was thrown
