EXTRACT
...Roger Geoffrey Gibbs was born in Hertfordshire in 1934, the son of Geoffrey Gibbs, a banker, and his wife, Helen. The family was influential and wealthy. His father ran Antony Gibbs & Sons, the bank set up in 1808 by Roger’s great-grandfather that helped to finance the Great Western Railway. His uncle Humphrey was the governor of Rhodesia, present-day Zimbabwe.
The fourth of six children, five of them boys, Roger was educated, as were all his brothers, his father and his grandfather, at Eton and later went on to Millfield in Somerset. The family grew up in grand style, living in large houses outside Hatfield and Oxford....
...Among his close friends was the disgraced aristocrat Lord Lucan, a school friend from Eton. Lucan borrowed £1,000 from Gibbs at one point. Gibbs believed that Lucan, who disappeared in 1974 after allegedly killing the family nanny, had jumped off a ferry with weights in his pockets....
...He was a workaholic who lived alone for most of his life and would drive for miles on foreign holidays to get a copy of the Financial Times — but at the age of 70 he finally married. His wife was Jane Lee, an old friend.
...Sir Roger Gibbs, businessman and philanthropist, was born on October 13, 1934. He died of multiple causes on October 3, 2018, aged 83
