Loel Guinness

On 31 December 1988, Guinness died of heart disease at The Methodist Hospital in Houston, Texas, United States. He was buried with the remains of his third wife at the Bois-de-Vaux Cemetery, Lausanne.

Through his son William, he was the grandfather of Sheridan William Guinness (born 1972), Thomas Seymour Guinness (born 1973), and Chloë Belinda Vane-Tempest-Stewart (born 1976), who married Lord Reginald Alexander Vane-Tempest-Stewart (born 1977).

Through his son Patrick and his stepdaughter Dolores, he was the grandfather of Maria Alexandra (born 1956), who married Foulques, Count de Quatrebarbes (born 1948) in 1979, Loel Patrick Guinness (born 1957), and Victoria Christina Guinness (born 1960), who married Philip Niarchos in 1984 (son of late Greek billionaire Stavros Niarchos).

Guinness's first marriage was to the Honourable Joan Barbara Yarde-Buller (1908–1997), a daughter of the 3rd Lord Churston. Before their divorce, Loel and Joan had a son, Patrick Benjamin Guinness (1931–1965), who married his stepsister from his father's third marriage, Dolores Maria Agatha Wilhelmine Luise, Freiin von Fürstenberg-Hedringen (1936–2012), on 22 October 1955 in Paris. He was killed weeks before their 10th wedding anniversary in an automobile accident near Rarogne, Switzerland.

In a reversal of the outcome of his first marriage, in 1951, Lady Isabel was granted a divorce after accusing him of adultery, which he did not contest.

On 7 April 1951, he married his third wife, the socialite Gloria Rubio y Alatorre (1913–1980), who had been the wife of Prince Ahmed Fakhry Bey of Egypt, grandson of King Fuad I of Egypt. Her daughter, Dolores married his eldest son, Patrick Benjamin Guinness (1931–1965).

Born in Manhattan and raised in the United States and England, Loel Guinness was the only son of Benjamin Seymour Guinness (1868–1947), an Irish lawyer from whom he inherited a fortune, and his first wife, Bridget Henrietta Frances Williams-Bulkeley (d. 1931). His father remarried with an Italian Duchess ( Maria Nunziante, suo jure Duchess) and was made (22 May 1946) a Prince (life title) by the King of Italy. He descended from Samuel Guinness, a Dublin goldsmith (1727–1795) and younger brother of the Guinness brewery's founder Arthur Guinness.

Guinness gained the rank of group captain in the service of the Royal Auxiliary Air Force. When the Second World War broke out in 1939, Guinness went on active duty with the Royal Air Force. In 1940 he flew as a fighter pilot in the Battle of Britain, famously buying a petrol station near his aerodrome when his driving was restricted by rationing. In 1944 he became commander of a wing of the Second Tactical Air Force and by the war's end he had been Mentioned in Despatches five times. He was invested as an Officer of the Order of the British Empire in 1942. The Netherlands made him a Commander of the Order of Orange-Nassau and France made him an Officer of the Legion of Honour and awarded him a Croix de Guerre.

Joan left him for Prince Aly Khan, the eldest son of the Aga Khan III, the 43rd Shia Imam, and Guinness successfully sued Joan and Khan on grounds of adultery. Joan and Khan did not defend the charges and the judge, Justice Bucknill, granted Guinness a decree nisi and full custody of their son and ordered Khan to pay court costs. Joan married Khan on 18 May 1936, a few days after the divorce became absolute. The Aly Khan's other son Patrick is a half-brother to the present Aga Khan IV. Joan and Khan also divorced and the Prince later married American actress Rita Hayworth, and Joan married the 2nd Viscount Camrose and was styled as Joan Berry, Viscountess Camrose.

In 1936, he married his second wife, Lady Isabel Violet Kathleen Manners (1918–2008), the second daughter of John Manners, 9th Duke of Rutland and Kathleen Tennant. His wife was prominent in society at Palm Beach. Together, they were the parents of a son and a daughter:

In 1931, on his third try, Guinness was elected to Parliament for Bath and was named parliamentary private secretary to Sir Philip Sassoon, the Under Secretary for Air from 1931 to 1935. He held his seat until 1945, when he stood down.

At his son's christening on 15 July 1931 at St Margaret's, Westminster, his godparents were Princess Ingrid of Sweden (1910–2000), Richard Francis Roger Yarde-Buller, 4th Baron Churston (1910–1991), Sir Philip Sassoon, 3rd Baronet (1888–1939), Walter Rosen (1875–1951), Judith Blunt-Lytton, 16th Baroness Wentworth (1873–1957), and Mrs. Richard Guinness (née Beatrice Mackay, formerly Mrs. Nico Jungman).

After taking flying lessons, Guinness joined the Royal Aero Club in 1928. The following year, he became one of the first private citizens in England to own an airplane and soon he was a member of the County of London's Auxiliary Air Force squadron. He later served as president of Air Work Ltd., an aircraft-parts supplier, and of British United Airways.
