Mme. Curie has not allowed her lectures in the Sorbonne to interfere with the continuation of the researches which have won for her such world-wide renown. Since the sudden taking off of her husband by a passing truck on a Paris bridge, she has succeeded in isolating both radium and polonium--only the chlorides and bromides of these elements were previously known--besides doing other work scarcely less remarkable. And besides all this, she has also found time to write a connected account of her investigations under the title of _Traite de Radio-Activite_--a work that reflects as much honor on her sex as did _Le Instituzioni Analitiche_ of Maria Gaetana Agnesi, which won for her, through that celebrated patron of learning, Benedict XIV, the chair of higher mathematics in the University of Bologna. The list of learned societies to which Mme. Curie belongs is an extended one. To mention only a few, she is an honorary or foreign member of the London Chemical Society, the Royal Institution of Great Britain, the Royal Swedish Academy, the American Chemical Society, the American Philosophical Society, and the Imperial Academy of Sciences of St. Petersburg. From the universities of Geneva and Edinburgh she has received the honorary degree of doctor. In 1898 she received the Gegner prize from the French Academy of Sciences for her elaborate researches on the magnetic properties of iron and steel, as also for her investigations relating to radio-activity. The same prize was again awarded to her in 1900, and still again in 1903. With her husband she received in 1901 the La Caze prize of ten thousand francs; and in 1903 she received a part of the Osiris prize of sixty thousand francs. Since her husband's death in 1906 Mme. Curie has been awarded the coveted Nobel prize in chemistry, which was placed in her hand by the King of Sweden on December 11, 1911--a prize which increased the exchequer of the fair recipient by nearly two hundred thousand francs. Having before been the beneficiary of the Nobel prize for physics, in conjunction with her husband and M. H. Becquerel, Mme. Curie is thus the first person to be twice singled out for the world 's highest financial recognition of scientific research. It would take too long to enumerate all the medals and prizes and honors which have come to this remarkable woman from foreign countries. But she has doubtless been the recipient of more trophies of undying fame during the last decade and a half than any other one person during the same brief period of intellectual activity. And all these tokens of recognition of genius were showered upon her not because she was a woman, but in spite of this fact. Had she been a man, she would have been honored with the other distinctions which tradition and prejudice still persist in denying to one of the proscribed sex, no matter how great her merit or how signal her achievements.
