Michael John Pentz (30 November 1924 – 29 May 1995) was a physicist, activist in the peace movement, and an influential pioneer of teaching science to university students by distance education. Pentz was born in Cape Town, South Africa, and died in France.
Life Pentz was educated in South Africa at St Aidan's College, Grahamstown, and went on to attend the University of Cape Town. He came to Imperial College in London in 1948 to work on microwave spectrometry and nuclear physics. Nine years later he joined CERN in Geneva, where he was appointed leader of a large group of scientists developing the CESAR accelerator facility.
Throughout his life, Pentz was a prominent member and activist in a number of highly committed political bodies. In 1965, while working at CERN, he became the first president of the newly founded Mouvement Anti-Apartheid Suisse. From 1981 to 1984, he was Vice-Chair of the Campaign for Nuclear Disarmament (CND). Together with fellow Open University academic Steven Rose, Pentz was instrumental in the movement Scientists against Nuclear Arms (SANA), which he set up in 1981; SANA was one of the forerunner organisations of Scientists for Global Responsibility (SGR).
For health reasons, Pentz retired to Bonnieux, near Avignon, in France. He died of leukaemia in 1995.
Career Student of physics and electrical engineering at University of Cape Town earning a BSc (Hons) degree (1944); this was followed by an MSc in physics (1945). 1948–49 Research assistant; 1949 assistant lecturer; 1949–57 lecturer, Department of Physics, Imperial College London 1957–58 Research fellow; 1958–68 senior physicist, CERN, Geneva 1969–85 Founding dean and director of studies, Faculty of Science, Open University In 1987, the Open University conferred the title emeritus professor onto Pentz.
Open University Since his early days in South Africa, where in 1943 he helped found the Adult African Night Schools Association,Rose, Steven. "The physicist who preached peace", The Guardian, 31 May 1995, Features, p. 14. to his time at CERN where he threw himself into extramural activities aimed at broadening educational opportunities and spreading scientific knowledge, Pentz had a passionate commitment to the public understanding of science. In 1969 he was invited by Walter Perry, the first vice-chancellor of the Open University, to become the founding dean and director of studies of the science faculty. He pioneered the teaching of science at a distance, overcoming not only a variety of practical difficulties, but also many prejudices against the notion that science could be taught by correspondence and television. Writing in 2006, Steven Rose described the immense challenge:
Led by newest research in educational technology, they overcame the difficulties by developing a multi-media approach, using printed texts, radio and television broadcasts, support from tutors in face-to-face tutorials, residential schools, and by the innovative use of home experiment kits.Video clip from the Open University Archive on OpenLearn, The Open University .

Having built on Pentz's work in establishing science education by distance teaching, the OU's Science Faculty today supports a large proportion of all the part-time science degree studies in the UK: as of 2012, there are about 48,000 (mainly UK-based) students studying OU undergraduate and postgraduate science modules.'About the faculty', Faculty of Science, The Open University .

Pentz's passion to inform and his belief that science could be taught to anyone who wanted to learn it also inspired many distance educators in other countries and continents to follow his example.
Peace work In Pentz's obituary, Labour politician Tam Dalyell wrote: "[...] no activist bestowed greater scientific respectability on, or devoted more energy to, the crusade against nuclear weapons than did Pentz. No big anti-nuclear weapons demonstration in the 1980s was complete without Pentz's large, lumberjacketed presence, leading a march or gracing a platform." As an opponent of nuclear deterrence and of NATO's doctrine of flexible response, Pentz believed that a nuclear war could not in any way remain limited, and would inevitably lead to widespread destruction. Consequently, Pentz became a vocal activist for nuclear disarmament, joining many significant peace marches of the 1970s and 1980s.

Pentz never sought to conceal controversial affiliations: he was, for example, a sponsor of the British arm of the leading Soviet front body, the World Peace Council (WPC). In May 1984, he went to Moscow at the invitation of the official Soviet Peace Committee to establish links with the Kremlin's "Scientific Research Council on Problems of Peace and Disarmament".
