Parmly Hearing Institute.

Established as the Parmly Foundation for Research in Hearing at the Illinois Institute of Technology, October 1942, through a trust fund left by Samuel P. Parmly, a Chicago businessman, the Parmly Hearing Institute seeks to solve problems in hearing through research. From its inception, Parmly regarded hearing difficulties as a bio-physics prblem and concentrated its work on the physics of hearing. in 1957, the foundation received a grant from the National Institues of Health and began a study of the psychological factors in hearing loss. By 1959 Parmly research revolved around three aspects: Physics, Psychology, and Physiology. The expansion of research to areas other than physics lead to the dissolutionof the Parmly Trust at IIT and the affiliation of the Institute with Loyola University Chicago in 1960. Also in 1959, the name of the institute was changed to the Parmly Hearing Insitute. Parmly has had six directors sinces its inception: Peter J. Mils (1943-1966); A. J. Derbyshire (1960-1963); Horacio J.A. (H. J. A.) Rimoldi (1969-1970); Terrence Dolan (1970-1977); William A. Yost (1977-2001); and Richard R. Fay (2001-present).
