Dr. Harold C. Urey at Spectrometer

(Original Caption) Professor Harold C. Urey, of Columbia University, winner in 1934 of the Nobel Prize for chemistry, shown at work on his mass spectrometer, with which he has succeeded in separating the heavy isotope of nitrogen for the first time, in quantities sufficient to provide a new "tagged" atom for far reaching investigations of physiological processes and other scientific enigma. Dr. Urey and his coworkers, Dr. John R. Huffman, H.G. Thode and Marvin Fox, have developed a chemical method by which two-tenths of a gram of "heavy" nitrogen can be produced every 24 hours, a speed 100 times greater than previously attained by scientists who had separated the isotopes or chemical "twins" by physical means based on diffusion of gases.
