Desmond Guinness

Desmond Walter Guinness (8 September 1931 – 20 August 2020) was an Anglo-Irish author of Georgian art and architecture, a conservationist and the co-founder of the Irish Georgian Society. He was the second son of the author and brewer Bryan Guinness, 2nd Baron Moyne, and his then wife Diana Mitford (later Lady Mosley). In 1958, he bought Leixlip Castle, Leixlip, County Kildare, Ireland, where he lived with both his first wife, Princess Henriette Marie-Gabrielle von Urach, generally known as Mariga, and later his second wife, the former Penelope Cuthbertson, whom he married in 1984. Life 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.
