Tuskegee Syphilis Study

Macon County, Alabama, United States · 1932–1972

From 1932 to 1972, the United States Public Health Service studied roughly 600 Black men in Macon County, Alabama — 399 with latent syphilis and 201 without — without informing the infected men of their diagnosis, and without offering them effective treatment even after penicillin became the standard cure in the late 1940s, in order to observe the untreated progression of the disease until death.

Marshall Islands Nuclear Testing

Bikini and Enewetak Atolls, Marshall Islands · 1946–1958

Between 1946 and 1958, the United States conducted 67 nuclear weapons tests in the Marshall Islands. The program transformed Bikini and Enewetak into proving grounds for increasingly powerful weapons and displaced island communities from ancestral homelands. The most consequential single test was Castle Bravo on 1 March 1954. Its explosive yield greatly exceeded the scale planners had expected. Radioactive fallout spread beyond the exclusion area and exposed people on Rongelap and Utrik, among others. The United States subsequently evacuated affected communities, conducted medical monitoring and created long-term health and environmental programs. The history is not only about radiation dose — it is also about consent, displacement, land, culture and power. The documentary record clearly establishes testing, relocation, fallout exposure and long-term contamination concerns. More difficult questions concern the precise health effects attributable to radiation in small populations, whether relocation decisions can meaningfully be described as consensual under a U.S.-administered strategic trusteeship, and whether later compensation mechanisms adequately addressed the losses.

British Nuclear Testing in Australia

Monte Bello Islands, Emu Field and Maralinga, Australia · 1952–1963

Between 1952 and 1963, the British government, with the agreement and support of the Australian government, conducted nuclear-weapons testing at the Monte Bello Islands, Emu Field and Maralinga. Australia's radiation-protection agency states that 12 major atomic detonations took place: three at Monte Bello, two at Emu Field and seven at Maralinga. In addition, numerous smaller trials investigated weapon components and safety; at Maralinga, some of these 'minor trials' dispersed plutonium and became the principal source of long-term contamination. The tests occurred in remote areas that officials treated as suitable for weapons work, but those landscapes were not empty: Aboriginal peoples, including Pitjantjatjara and Yankunytjatjara communities, had longstanding relationships with the land, and the National Archives of Australia states that their permission was not sought. Growing concern eventually led the Australian government to establish the McClelland Royal Commission in 1984. Its work examined safety, radiation exposure, contamination and the treatment of Aboriginal communities. Later remediation removed or contained contaminated material, but the testing program left a legacy of disputed health claims, cultural loss, environmental damage and institutional mistrust.

MKUltra

United States (multiple sites) and Canada, United States · 1953–1973

Between 1953 and 1973, the CIA ran MKUltra, a program of roughly 150 subprojects researching behavioral modification and interrogation techniques — including LSD and other drugs, hypnosis, sensory deprivation and electroshock — conducted at universities, hospitals and prisons, in many cases on subjects who were not informed they were part of an experiment. CIA Director Richard Helms ordered most MKUltra records destroyed in 1973, so the program's full scope and human toll are not fully known.
