In the 1960s, Finkelstein was imprisoned for his anti-apartheid activities. Following a spell of hard labour, he was issued with a five-year banning order (1967–1972) under the Suppression of Communism Act. Finkelstein came to the UK in 1968 as a refugee and joined the emergent British disability movement. Finkelstein cites his first hand experiences witnessing
apartheid and his treatment by South African police as a disabled person, as experiences that initiated new ways of thinking about society and its oppression of disabled people. In the UK in 1972 Finkelstein co-founded
Union of the Physically Impaired Against Segregation (UPIAS) with Paul Hunt. UPIAS was the first organisation to reject 'compensatory' and tragic or medical approaches to disability. As an alternative, UPIAS developed attention to the social and structural barriers that oppress people with impairments, rendering them 'disabled'. This led to the development of the
social model of disability. == Academic career ==
