Physician, politician, activist, author, wife and mother are just some of the roles undertaken by Caldicott, who was raised in Australia. Her dissidence dates back to 1971 when she was instrumental in Australia's opposition to atmospheric nuclear testing conducted by the French government in the Pacific. In 1975, she worked with Australian trade unions to educate workers on the dangers of the nuclear fuel cycle. As a resident of the United States from 1977 to 1986, she founded the Physicians for Social Responsibility, an organization of 23,000 physicians committed to educating their colleagues about the dangers of nuclear powers, nuclear weapons and nuclear war. Through her travels, she established similar organizations abroad and the parent organization, International Physicians for the Prevention of Nuclear War, won the Nobel Peace Prize in 1985.
