Early life and marriage Born on 8 September 1931, Guinness was the second son of the author
Bryan Guinness and
Diana Mitford; his elder brother was
Jonathan. Bryan succeeded as the 2nd
Baron Moyne in November 1944. Desmond's mother divorced the then Bryan Guinness after five years and married the head of the British fascist Blackshirt movement,
Oswald Mosley, in
Berlin in 1936. Due to Mitford's interest in fascism, her father-in-law the
1st Baron had arranged for surveillance from 1935 onward, including by one of Guinness's governesses, and
MI5 even noted a plan for her to visit
Hitler with her sons. Mitford was interned in 1940, and Guinness later recalled visiting her in
Holloway Prison when he was 10. He was educated at
Eton and
Gordonstoun, and studied French and Italian at
Christ Church, Oxford. After completing
National Service, he moved to the estate of Lord Moyne, his father, near the
Phoenix Park in
Dublin, as Lord Moyne lived for six months a year in
Ireland, and his mother had also moved to Ireland with Mosley, first living in
Clonfert, then in
Fermoy.
Irish Georgian Society Desmond and Mariga founded the
Irish Georgian Society in April 1958 to help to preserve Irish architecture of all periods. This was timely as the Irish planning laws were enacted only from 1963. The IGS became involved in numerous projects and started publishing quarterly bulletins. Some early preservations or campaigns were at:
Damer House (
County Tipperary),
The Conolly Folly (
County Kildare),
Mountjoy Square,
Tailors' Hall and
Hume Street (
Dublin) and the Dromana Gateway in
County Waterford. The IGS also held Georgian
cricket matches played to the
rules of 1744. Between 1967 and 1979 the Guinnesses bought and started to preserve
Castletown House, in
Celbridge,
Kildare, said to be the finest Palladian house in Ireland.
Other philanthropic and social activities He was a member of Irish groups such as the
Iveagh Trust, the CKAS, the RIAC and the
Kildare Street & University Club.
Later life In 1984, Guinness married Penelope Cuthbertson, daughter of the socialite
Teresa Jungman, and a granddaughter of the artist
Nico Wilhelm Jungmann. He was
Master of the North Kildare Harriers. He stood down as President of the IGS in 1990. Guinness died on 20 August 2020, at the age of 88. ==Family==
