Birth, family and marriage
Constantine FitzGibbon was born in the United States in 1919, the youngest of four children. He was a half-brother of Louis FitzGibbon, author of a number of works about the Katyn massacre of Polish officers in 1940, by Soviet troops. His father, Commander Francis Lee-Dillon FitzGibbon, RN, was Irish, and his mother, Georgette, daughter of George Winthrop Folsom, was an American from Lenox, Massachusetts.
The family were descended from John "Black Jack" FitzGibbon, the 1st Earl of Clare, who was Lord Chancellor of Ireland and effected the Act of Union between Ireland and England in 1800, but in the following century the family faded into obscurity and the title died out. Constantine FitzGibbon's grandmother, Louisa, was daughter of the third and last Earl; her husband, Captain Gerald Normanby Dillon, sixth son of Henry Dillon, 13th Viscount Dillon, changed his name to FitzGibbon so the name could continue.
He was brought up in the United States and France before moving to England with his mother, his parents having divorced when he was very young. His first brief marriage was to Margaret Aye Moung, but during World War II he met Theodora Rosling, to whom he was married until 1960. They lived at Sacombs Ash, Hertfordshire, from 1951–59, but had no children. Theodora wrote of their time together in her (partly fictional) memoirs With Love (1982), and Love Lies a Loss (1985). Their lives were Bohemian. The union ended in divorce.
He then married Marion Gutmann in 1960, with whom he had a son, Francis, born in 1961. Their marriage ended in 1965, and he moved to Ireland and married Marjorie Steele, a retired American actress, in 1967. They had a daughter, Oonagh (born 1968), for whom he wrote Teddy in the Tree (1977). He also adopted Marjorie's son, Peter FitzGibbon, from her former marriage. After a short spell in west Cork, the family lived in Killiney, County Dublin, and then in the city.

FitzGibbon was educated at Wellington College, Berkshire, a British public (i.e. private) school with military affiliations, which he detested. He left aged 16 and travelled independently in Europe, where he studied at the University of Munich and University of Paris, becoming fluent in French and German and acquiring a sound knowledge of their literatures.
He won a scholarship to Exeter College, Oxford to read modern languages in 1937, but left in May 1940, after the fall of France, to join the army. He did not complete his degree before the war and chose not to return to Oxford afterwards. One of his best novels, The Golden Age (1976), set in a post-apocalyptic future Oxford, is by turns wistful and sardonic about the University.

FitzGibbon served as an officer in the Oxfordshire and Buckinghamshire Light Infantry (the 'Ox & Bucks') regiment of the British Army, from 1940 to 1942. As a US citizen he transferred to the United States Army in 1942, when the United States entered the war, rising to the rank of Major by 1945. His work was in intelligence, and he served as a staff officer to General Omar H Bradley in the D-Day campaign and thereafter.
On being discharged in 1946, FitzGibbon was offered, but refused, a job with the successor to the Office of Strategic Services(OSS), a predecessor of the Central Intelligence Agency (CIA). Instead, he worked briefly as a schoolmaster at Saltus Grammar School in Bermuda from 1946–47, before becoming a full-time independent writer. He lived in Italy for a time, where he tried and failed to write a biography of Norman Douglas, a distant kinsman. Between 1950 and 1965 he was resident in England.
FitzGibbon wrote over 30 books, including nine novels, and translated numerous works from German and French. One of his closest friends was the writer Manes Sperber, many of whose books he translated from French and whose views about the dangers of both left-wing and right-wing tyranny were highly influential on him.
Politically, FitzGibbon identified himself as a strong anti-Communist, having been drawn to communism as a young man. His credo, however, was that no political group that resorted to locking its opponents up in camps was any good. He refused to travel to Spain while Franco was alive. During the Troubles in Northern Ireland, he supported civil rights for Catholics but condemned the use of violence by all sides.
His 1960 novel, When the Kissing Had to Stop caused controversy because of its explicit anti-CND theme; the book depicts the Soviet domination of Britain under a left-wing government which has removed its nuclear weapons. An ITV adaptation of When the Kissing Had to Stop caused even more controversy, and one writer called FitzGibbon a "fascist Hyena". This amused him greatly, and he responded by publishing a collection of essays called Random Thoughts of a Fascist Hyena (1963).
He wrote prolifically, in fiction, historical works, memoirs, poetry and biography. He made programmes for BBC radio, including documentaries about British fascism, the Blitz and the 1930s hunger marches. He was a regular contributor to newspapers in the UK and Ireland, and for many years wrote for Encounter (magazine). His one stage venture, The Devil at Work (produced by the Abbey Theatre, Dublin in 1971) met with little success.
FitzGibbon was a member of the Council of the Irish Academy of Letters and an honorary fellow of the Royal Society of Literature and a Guggenheim Fellow. He later became an Irish citizen and lived in County Dublin.
