He returned to the University of Idaho in 1926 to teach, and became the head of the physics department in 1930, a position that he held for sixteen years. He led a productive materials science laboratory and was mindful of practical applications of his research—for example, as an extension of
22:(Gustav Vilhelm Hammar) (June 22, 1893 – August 19, 1954) was a Swedish-born American experimental physicist. He was the eldest of six children of Anders Vilhelm Hammar and Elin Christina Hammar (nÊe Olsson). He emigrated to the United States in 1913, attended 53:, he and his student Lawrence W. Foskett developed a telephone using light instead of copper wire for transmitting signals. At present, however, Hammar is best remembered for an experiment that was quite outside of his main area of research, the 80:
