Pioneer in LCD technology, visionary innovator and physicist
Professor Cyril Hilsum is a visionary innovator and physicist. His contributions to semiconductor physics research were among the earliest in the field, and continue to be reflected across industry, academia and government.
Born in May 1925, Cyril began his scientific career in the Royal Naval Scientific Service, which formed part of his national service duties. Here, he grew his interest in infrared technologies, later transferring to the infrared group in the Admiralty Research Laboratory.
During his time in Teddington, Cyril pioneered work on indium antimonide and gallium arsenide, building the team’s reputation as a hub for the development of high temperature semiconductors. This work and its various commercial applications led Cyril to create the UK’s first semiconductor laser.
Following this, Cyril joined the Radar Research Establishment at Malvern, where he was tasked with leading a programme on flat-panel displays. His research recommendations here formed the foundation of the LCD screen technologies still enjoyed to this day.
Cyril’s work has been widely recognised through industry accolades and government positions. By 1983, he was leading the GEC Hirst Research Centre, and as a research advisor for the European Commission. In 1978, Cyril was elected Fellow of the Royal Academy of Engineering.
