Born to Jewish parents in Kiev, in the Russian Empire (present-day Ukraine), Sir Leon studied law at Birkbeck College in the University of London, formed his own company in 1935, and for many years headed the revamped firm of Elliott-Automation Ltd., which, outside the United States, was the largest computer manufacturer in the world.^[1]

Leon Bagrit was a member of the Council for Scientific and Industrial Research, 1963–1965 and the Advisory Council on Technology, 1964-1979. He was a director of the Royal Opera House, Covent Garden, 1962-1970. He founded the Friends of Covent Garden, and chaired it, 1962-1969. In 1964, he was invited by the BBC to present the Reith Lectures.^[2] Across six broadcasts, titled The Age of Automation,^[3] he explored how the increased technological development of the time would change people's lifestyles, and the wider world.

Due to the generosity of the Bagrit Trust, a dedicated building, the Sir Leon Bagrit Centre, was opened in the summer of 1991. This Centre formed a cornerstone of the Department of Bioengineering at Imperial College London and the next step in the development of bioengineering at Imperial.^[4]
