John Robert Porter

John Robert Camber Porter (5 January 1953 – 10 November 2021) was an English businessman best known as the grandson of Sir Jack Cohen, founder of Tesco, and son of Dame Shirley Porter.

Early life and education When John Porter was young, he was given £4 million by his grandfather, Sir Jack Cohen, the founder of Tesco. He was educated at Highgate School and obtained degrees from Oxford, the Institute d’Etudes Politiques in Paris, and Stanford Graduate School of Business, where he has also served on the advisory council.

A key plank in John Porter's empire was said in 2000 to be the fortune he had made out of the US computer company Telos, based in Virginia, which has close ties to the Pentagon. Telos was originally called C3, and specialised in the communication systems that formed the backbone of the US Army.

In 2016 Porter joined the Board of Trustees of UK charity Paintings in Hospitals.

Porter died of lung cancer on 10 November 2021, aged 68, after a 5-year illness.
