I found this passage in "Mission Communications - The Story
of Bell Laboratories:"

 "Bell Laboratories research studies of certain semiconductor
compounds by D. G. Thomas, J. J. Hopfield, C. J. Frosch and others
at the Laboratories led to the discovery of the basic physical
process by which light is created in gallium phosphide
light-emitting diodes (LEDs)......"

The book was written by Prescott C. Mabon and used to be available
from Bell Labs, Murray Hill, NJ 07974.
