This apparatus assembly was used to make measurements of radioactivity by the Curies. This is the same device that was prominent in the laboratory work shown in the movie "Madame Curie" starring Greer Garson and Water Pidgeon, released in 1943. The entire assembly included an ionization chamber, an electrometer, and piezoelectric quartz. This assembly was invented and designed by the Curies specifically for measuring radioactivity -- the Geiger counter, which is used today, was not invented until Hans Geiger developed his device in 1908 while working for Ernest Rutherford at the University of Manchester. See next four photos for individual descriptions of the three main component and miscellaneous items.
