Jan Morris previously wrote under the name .

Jan Morris is a British historian, author and travel writer. Morris was educated at Lancing College, West Sussex, and Christ Church, Oxford, but is Welsh by heritage and adoption. Before 1970 Morris published under her former name, James Morris, and is known particularly for the Pax Britannica trilogy, a history of the British Empire, and for portraits of cities, notably Oxford, Venice, Trieste, Hong Kong, and New York City, and has also written about Wales, Spanish history and culture.

Morris was assigned male at birth, and before circa-1970 was known as James Morris. In 1949, as James, Morris married Elizabeth Tuckniss, the daughter of a tea planter. Morris and Tuckniss had five children together, including the poet and musician Twm Morys. One of their children died in infancy. As Morris documented in her memoir Conundrum, she began taking oestrogens to feminise her body in 1964. In 1972, she had sex reassignment surgery in Morocco. Sex reassignment surgeon Georges Burou did the surgery, since doctors in Britain refused to allow the procedure unless Morris and Tuckniss divorced, something Morris was not prepared to do at the time. They divorced later, but remained together and have now had a civil union. On May, 14th, 2008, Morris and Tuckniss remarried each other. Morris lives mostly in Wales, where her parents were from.
