My son, Richard Orna, who has died aged 40 of a brain tumour, was an inspiring and well-respected IT manager. In his last years he became an ambassador for Brain Tumour Research.
As managing director of Callisto, an energy solutions company, Rick had vision and strategy. He worked to secure the IT for its smart meters and ensured that half-hourly readings could be delivered. He also supervised the takeover of a rival IT company, bringing it within Callisto to make their product more secure.
