Ursula Moray Williams (19 April 1911 – 17 October 2006) was an English children's author of nearly 70 books for children. Adventures of the Little Wooden Horse, written while expecting her first child, remained in print throughout her life from its publication in 1939. Her classic stories often involved brave creatures who overcome trials and cruelty in the outside world before finding a loving home. They included The Good Little Christmas Tree of 1943, and Gobbolino, the Witch's Cat first published the previous year. It immediately sold out but disappeared until re-issued in abridged form by Kaye Webb at Puffin Books twenty years later, when it became a best-seller. Life Williams was born in Petersfield, Hampshire, by ten minutes the younger of identical twins. She and her sister Barbara Árnason were talented artists and for six years from the age of ten wrote and illustrated books for each other's birthdays and at Christmas. Both were enthusiastic Girl Guides, attending some of the movement's first camps, and some of Ursula's early books were collections of stories she had told to her own Brownie pack. The girls were also keen riders – on hobby horses at first. To save for a pony they kept goats, selling their milk which they refused to drink themselves. Thanks to their uncle, the publisher Stanley Unwin, the twins visited the Alps, which later inspired some of Ursula's most vivid writing, most notably the trilogy that began with The Three Toymakers. Its final volume, The Toymaker's Daughter, was among her most celebrated creations. Williams' greatest source of ideas, however, was the house in which she spent her teenage years, North Stoneham House, a large, dilapidated mansion set in woodland north of Southampton. Events from her childhood recur repeatedly in her fiction, with North Stoneham described at greatest length in the 1941 A Castle for John-Peter and depicted in Faith Jaques’ illustrations for Grandpapa's Folly and the Woodworm-Bookworm of 1974. She was a friend of Puffin Books editor Kaye Webb, and organised riotous parties for the Puffin Club, of which she was made the first honorary member. She worked with illustrators like Shirley Hughes, Faith Jaques and Edward Ardizzone. Much of her later writing included disruptive, but essentially good-hearted children, and was influenced by her work as a juvenile magistrate and as a highly involved school governor. Locally, she was greatly admired for her many acts of kindness
