Gr. helios, the sun). Janssen obtained the first evidence of helium during the solar eclipse of 1868 when he detected a new line in the solar spectrum. Lockyer and Frankland suggested the name helium for the new element. In 1895 Ramsay discovered helium in the uranium mineral clevite while it was independently discovered in cleveite by the Swedish chemists Cleve and Langlet at about the same time. Rutherford and Royds in 1907 demonstrated that alpha particles are helium nuclei. 

In spite of the excitement the race to transmutation had spurred in the worlds of chemistry and occult alchemy, the crash came in 1914. The prestige and identity transmutation efforts had conferred upon chemistry were called into question—by physicists. Criticism had already come heavily from physicists such as J. J. Thomson, who debunked some of the experiments following the announcement of the Chemical Society meeting in February 1913, as well as from Rutherford, Royds, and Robert John Strutt (Lord Rayleigh). Even sympathetic chemists such as Madame Curie had been unable to reproduce Ramsay s results. Ramsay s own student and research partner, Egerton, could not successfully repeat the experiments when he went to work in a lab in Berlin.

One of the physicians, Royd Sayers (1885—1965), was new to industrial medicine. Born in the small Indiana town of Crothersville, where his father owned a jewelry store, Sayers had studied chemistry at the University of Indiana. After working as a chemist for three years, he enrolled in the medical school of the University of Buffalo, teaching chemistry while pursuing his studies. Upon completing his internship in 1915, he joined the Public...
