Kozuma, Cal Gough, Andy Elliott, Sanford Berman, James A. Paulsen, and Peggy Hanley-Hackenbruck.

The later exchange of correspondence, 1985-1991, refers to the successful effort to remove "Homosexuality" from disparaging headings in the World Health Organization's International Classification of Disease.
