René Guillot (1900-1969) was a French writer. He taught mathematics in Dakar, in Senegal, where he taught for over 20 years. He travelled throughout the country during this time, and set many of his stories there. He wrote widely for children and adults, and in 1964, received the Hans Christian Andersen Award, which is presented to an author whose “complete works have made a lasting contribution to children’s literature.”
He wrote two books about horses: The Wild White Stallion, set in the Camargue, and Riders of the Wind. The Wild White Stallion was based on the film Crin Blanc (White Mane), a short (47 minute) film directed by Albert Lamorisse and released in 1953. The film is available, with The Red Balloon, on DVD and Blu-Ray.
Finding the books: The Wild White Stallion is reasonably easy to find in hardback, though prices do vary. It is very easy to find in its British paperback translation. The American edition is usually ex library, but is not impossible to find.
