Christopher Hanson Abbott, a trailblazer in Australian computing and co-founder of the nation's first computer company, has died at the age of 89. Abbott passed away peacefully at his home in Sydney on July 8, 2026, surrounded by family.
Early Life and Education
Born on March 12, 1937, in Melbourne, Abbott showed an early aptitude for mathematics and engineering. He studied electrical engineering at the University of Melbourne, graduating with honours in 1958. After a brief stint at the University of Cambridge, where he worked on early mainframe systems, Abbott returned to Australia in 1961.
Founding the First Australian Computer Company
In 1963, Abbott co-founded Australian Computer Industries (ACI) with fellow engineer John McArthur. ACI developed the first fully Australian-designed and manufactured computer, the ACI-100, which was released in 1965. The machine was used by government agencies and universities, marking a significant milestone in the country's technological independence. According to the Australian Computer Society, the ACI-100 was capable of performing 10,000 calculations per second, a remarkable feat at the time.
Later Career and Legacy
Abbott led ACI until its acquisition by a US firm in 1978. He then turned to academia, becoming a professor of computer science at the University of New South Wales, where he mentored a generation of Australian tech entrepreneurs. In 1995, he was appointed an Officer of the Order of Australia for services to the computer industry. Abbott is survived by his wife of 60 years, Margaret, three children, and seven grandchildren. His contributions laid the groundwork for Australia's modern tech sector, which now employs over 100,000 people.
