What was Gerald Cavendish Grosvenor's Net Worth?

Gerald Cavendish Grosvenor was a British aristocrat, hereditary peer, businessman, and Territorial Army general who had a net worth of $12 billion at the time of his death. The 6th Duke of Westminster, Gerald Cavendish Grosvenor chaired his family's property company, Grosvenor Group. For most of his life, he was the richest person in England. He owned land across the country, including his family's country seat of Eaton Hall, and also presided over several charities.

Early Life and Education

Gerald Cavendish Grosvenor was born on December 22, 1951 in Omagh, County Tyrone, Northern Ireland to Robert Grosvenor, 5th Duke of Westminster and Viola Grosvenor, Duchess of Westminster. The family made its fortune through lease constructions in the 17th century and numerous property developments over the ensuing centuries. As a youth, the Duke lived on an island in Lough Erne in Northern Ireland. At the age of seven, he went to England to attend boarding school at Sunningdale School. He subsequently attended Harrow School. The Duke was bullied and ostracized during his time in boarding school, and left with two O-levels in history and English.
