Nicholas Mosley

Nicholas Mosley, 3rd Baron Ravensdale (25 June 1923 – 28 February 2017), was a British peer, novelist and biographer. Two of his volumes of biography covered the life of his father, Sir Oswald Mosley, the founder of the British Union of Fascists.

Mosley was born in London in 1923. He was the eldest son of Sir Oswald Mosley, 6th Baronet, a British politician, and his first wife, Lady Cynthia Mosley, a daughter of George Curzon, 1st Marquess Curzon of Kedleston (a Viceroy of India and at the time of Mosley's birth Foreign Secretary). In 1932, Sir Oswald founded the British Union of Fascists and became an open supporter of Benito Mussolini. The following year, when he was only nine, Nicholas's mother, Lady Cynthia, died, and in 1936 Diana Mitford, one of the Mitford sisters, who was already his father's lover, became his stepmother.

As a young boy, Mosley began to stammer, and he attended weekly sessions with the speech therapist Lionel Logue to help him manage it. He later recalled that his father said he never really noticed this stammer, but still, he may, as a result of it, have been less aggressive when speaking to him than towards other people. Mosley was educated at Eton and Balliol College, Oxford. In 1940, his father was interned because of his campaigning against the war with Germany. The younger Mosley was soon commissioned into the Rifle Brigade and saw active service in Italy, winning the Military Cross in 1945.

Following the war he studied philosophy at Oxford for a short time before marrying, taking to farming in north Wales before ultimately concentrating on his writing, primarily as a novelist but also producing several biographies.

In 1966, Mosley succeeded his aunt Irene Curzon, 2nd Baroness Ravensdale, his mother's elder sister, as Baron Ravensdale, thus gaining a seat in the House of Lords; he did not use the title. On the death of his father, on 3 December 1980, he also succeeded to the Mosley baronetcy of Ancoats. In 1983, two years after his father's death, Mosley published Beyond the Pale: Sir Oswald Mosley and Family 1933–1980 in which he proved to be a harsh critic of his father. He called into question his father's motives and understanding of politics. The book contributed to the Channel 4 television programme Mosley (1998), based on Oswald Mosley's life. At the end of the serial, Nicholas is portrayed meeting his father in prison to ask him about his national allegiance.

He was a half-brother of Max Mosley, former President of the Fédération Internationale de l'Automobile (FIA).

Mosley died on 28 February 2017 and is buried in the western side of Highgate Cemetery.

Mosley married twice and was the father of five children. On 14 November 1947, he married firstly Rosemary Laura Salmond (divorced 1974, died 1991), daughter of Sir John Maitland Salmond and the Honourable Monica Margaret Grenfell, and they had four children:
