Diana Pullein-Thompson

Diana Farr (; 1 October 1925 – 21 September 2015), was a British horsewoman and writer known for her pony books. Her mother and two sisters also wrote and together they created a large number of children's books, many of which were on the theme of horses.

Life Pullein-Thompson was born into a notable family. Her father, Harold Pullein-Thompson, had the Military Cross and her mother, Joanna Cannan, was a prolific and successful author. She was the first of twins. She had an elder sister and an elder brother. He adopted his mother's name and become an actor and a successful comedy playwright as Denis Cannan. All the sisters became writers.

The family home was a villa in the suburb of Wimbledon. Diana's father was badly wounded in the war and in frequent pain (and a bad mood). He had earned the Military Cross. He had just survived when many of his fellows had been killed. The girls had an unusual education, unlike their brother who went to Eton College; they were taught by their mother. The riding school brought in extra money as the three sisters taught others to ride.

In 1946 she had her first book, I Wanted a Pony,

The twins, Diana and Christine intended to be professional horse riders in America. Christine went to Virginia, but Diana was denied entry to the USA in 1952 as the medical revealed that she had tuberculosis. She was sent to recover in Switzerland courtesy of the country's new National Health Service.
