Alfred N. Goldsmith

Alfred N. Goldsmith was chief broadcast engineer of the Radio Corporation of America (RCA) (RCA) at the time of the 1927 press coverage of Palmer H. Craig's Hall-effect device.

Role in the source

The Radio World article of January 29, 1927 (byline Robert Bangs, p. 11) reported that Westinghouse Electric & Manufacturing Company had offered $100,000 for Craig's device. The same article records Goldsmith's response: he "denied that any such offer has been made" and "deprecates the idea that the peculiar property of bismuth can be used for the purpose claimed by Dr. Craig."

Goldsmith's denial is the earliest documented institutional rejection of the claim in the dossier, preceding the 1927 technical rebuttals by C. W. Heaps and Harry F. Breckel.
