About Mike Jensen
Born 1958. Mike Jensen is a South African computer scientist.
Mike Jensen (born 1958) is a South African ICT expert who was inducted into the Internet Hall of Fame as a "Global Connector" in 2017. He is particularly known for his work to build networks connecting the non-profit sector and for assisting developing countries to establish network connectivity.
Education Jensen grew up in Johannesburg in South Africa, the son of Anton Jensen and Berrell Jensen (née Jay), a contemporary sculptor. He studied biology at Queen's University Belfast from 197680 and, as a post-graduate at the University of Guelph in Canada, specialized in acid-rain pollution research. However, he began to question the value of writing scientific papers that seemed to have little impact on policy making. At that time the Reagan administration in the USA was denying the linkage between pollution and acid rain and Jensen started to write about pollution for student newspapers. After receiving his MSc he returned to South Africa and was, for a time, a technology journalist on the anti-apartheid Rand Daily Mail.
Early innovations When the Rand Daily Mail closed down in 1985 due to its inability to attract advertisers as a paper that targeted both black and white readers, Jensen decided to emigrate to Canada. In 1982, while studying for his MSc, he had been introduced to the CoSy online messaging system. CoSy was being developed by the University of Guelph and was subsequently selected in 1985 by Byte magazine for that magazine's BYTE Information eXchange, a networked bulletin board. While he waited in Toronto for his Canadian immigration clearance in 1986, Jensen opened a computer account at the University of Toronto that was using Usenet newsgroups for online discussions and information sharing. He had started volunteering with the Ontario Environmental Network (OEN) and wondered whether something similar to Usenet could be put together for environmental groups.
In the early days of internet, technicians had to travel to install software and to programme code to allow different systems to communicate with each other. Jensen was one of several who travelled extensively to install software and work with local technicians to link NGO networks to APC, using a "mother system" based on that in use at IGC Internet. He worked with Pegasus Networks in Australia, and with Micro-computing for Non-Governmental Organizations (MANGO) in southern Africa, where he started to use the Fidonet bulletin-board system, which proved effective to use with the poor phone lines available in much of Africa. This innovation then took him to GreenNet in London in order to upgrade the APC system to enable the smaller NGOs using Fidonet to gateway with the APC hosts, allowing them to use directly email services and information newsgroups offered by APC members. He then returned to South Africa to install a gateway at WorkNet, the South Africa APC partner that had been set up in 1987. By the end of 1991, Jensen and others had helped join seven African countries to the APC network.
Internet Hall of Fame In 2017 Jensen, was inducted into the Internet Hall of Fame as a "Global Connector". In 2012 he had served as a member of the Advisory Board to choose the first inductees to the Hall of Fame, who included Al Gore, Tim Berners-Lee, Linus Torvalds and Jimmy Wales.
Publications Jensen's publications include: The community telecentre cookbook for Africa: Recipes for self-sustainability. 2001. Promoting the Use of Internet Exchange Points: A Guide to Policy, Management, and Technical Issues. 2012. Towards financial sustainability in community-based networks. 2018.
