Joseph Sonnabend
physician, scientist and HIV/AIDS researcher (1933-2021)
Joseph Adolph Sonnabend (6 January 1933 – 24 January 2021) was a South African physician, scientist and HIV/AIDS researcher, notable for pioneering community-based research, the propagation of safe sex to prevent infection, and an early multifactorial model of AIDS.
As one of the first physicians to notice among his gay male patients the immune deficiency that would later be named AIDS, during the 1980s and 1990s he treated many hundreds of HIV-positive people. During the height of the AIDS crisis, Sonnabend helped create several AIDS organisations, including the AIDS Medical Foundation (now amfAR), the nonprofit Community Research Initiative (now ACRIA), which pioneered community-based research, and the PWA Health Group, the first and largest formally recognised buyers' club.
Sonnabend became controversial for advocating that gay men change their sexual behaviors to avoid sexually transmitted infections, rather than to just have fewer sexual partners, as advocated by Gay Men's Health Crisis and other gay community organizations, and for hypothesizing a multi-factorial model of causation, including for a period of time after discovery of HIV. He was widely respected as a pioneering and compassionate clinician and researcher.
Background
Sonnabend was born on 6 January 1933 in Johannesburg, South Africa, and grew up in Bulawayo, Southern Rhodesia (now Zimbabwe). His mother was a physician and his father a sociologist. Both parents were Jewish immigrants from Europe.
He trained in infectious diseases at the University of the Witwatersrand in Johannesburg and the Royal College of Physicians of Edinburgh. During the 1960s he conducted research at the National Institute for Medical Research in London, where he worked under Alick Isaacs, a pioneer of interferon research.
In the early 1970s Sonnabend moved to New York City to be an associate professor at the Mount Sinai School of Medicine. After losing his interferon research grant he worked at Kings County Hospital Center and as Director of Continuing Medical Education at the Bureau of VD Control for the New York City Department of Health.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Joseph Sonnabend”, the useful work is to connect “physician, scientist and HIV/AIDS researcher (1933-2021)” to the records capable of establishing context and consequence.
Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Sep 1, 2026. The linked authority identifier is Q6287101. VIAF identifies the subject as 76011218. The Library of Congress control number is no2003088040. 2 of 4 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1933 and 2021.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
