Paddy Chew

AIDS Activist

Paddy Chew, 39, an AIDS activist who was the only person in the conservative city-state of Singapore to publicly admit he had the ailment, died as its result Aug. 21 in Singapore.

He revealed he had AIDS during Singapore's first conference on the disease last December. He campaigned vocally for greater awareness of the disease and tolerance for its victims. AIDS continues to carry a deep social stigma in Singapore, and victims of the disease usually conceal their condition, flying overseas to be tested or to receive medical treatment.

Official statistics say that transmission of the disease has been chiefly by heterosexual sex with prostitutes. The homosexual community, of which Mr. Chew was a member, is unhappy about the government's refusal to publicly discuss the transmission of AIDS through homosexual sex, which remains illegal in Singapore.

Donald Louis Mason

FBI Agent

Donald Louis Mason, 74, an FBI agent whose interest in art led to the creation of a loosely organized unit within the bureau's major theft squad in New York that targeted art thieves, died of cancer Aug. 10 in Haworth, N.J.

His investigations included a widely publicized case in 1976, when film director Otto Preminger reported the theft of a Kandinsky painting "Leise Deutung" ("Soft Interpretations") from his New York office.

Robert Byck

Brain Researcher

Robert Byck, 66, a Yale University medical school brain researcher who in 1979 gave Congress an early warning about smokable cocaine, died Aug. 9 in Boston after a stroke.

In 1979, Dr. Byck told the House Select Committee on Narcotics Abuse and Control that smoking coca paste gives a very intense, and almost immediate, high. He said that the United States did not have an epidemic of freebase or coca-paste smoking but that the possibility of one strongly existed.
