Mr. Bond died on Feb. 13 in a hospital in Far Rockaway, Queens. He was 94. Deborah Callahan, a family friend, confirmed the death, which was not widely reported at the time, and said he had suffered from congestive heart failure.

“TES was really a new kind of kinky organization in that it was social, political and educational,” said the feminist author and cultural anthropologist Gayle Rubin, who has written extensively about sexual subcultures.

Dr. Rubin, who is an associate professor of anthropology and women’s and gender studies at the University of Michigan, added: “TES expanded the organizational repertoire of sadomasochism. In addition, Pat Bond and Terry Kolb began to develop a political language for S-and-M.

“They were able to do that in part because of the times. It was a period when many social movements were articulating political frameworks for various populations that had been marginalized. They also drew from the language of gay liberation, where there was already a model for repositioning what had been seen as sexual deviation as a sexual minority. To do this for sadomasochism was pretty breathtaking at the time.”
