June Finer took part in civil rights protests during Freedom Summer through the Medical Committee for Human Rights, beginning a long career at the intersection of medicine and activism. Finer became politicized while interning at a Chicago hospital in 1960, when she saw the different levels of care for patients of different races, and began working for fair treatment in Chicago hospitals. She became involved with MCHR, first taking part in Freedom Summer in 1964 and then returning in 1965 as the group’s southern coordinator, dispatching medical volunteers to be on hand at protests and to document injuries when protestors were arrested and jailed. She went on to work at the Women’s House of Detention at Rikers Island before establishing the Judson Mobile Health Unit, a “guerilla medicine” clinic in a trailer on the Lower East Side in Manhattan that offered free immunizations, medical care, day care, and literacy programs. She also served at an abortion clinic in the early 1970s before beginning work with drug addicts at the Lower East Side Service Center in 1980. She retired to New Paltz, New York in 1999.
