After his marriage to her in 1946, they came to London and he continued to make a rather tenuous living from lecturing and teaching until the beginning of the fifties, when he provided a centre for unemployed actors, on occasional days, at a hall in Loudoun Road, St John's Wood.
There he produced plays in the round including Philoctetes and Pinocchio, which he wrote with Warren Jenkins and an abbreviated version of The Man Born to Be King by Dorothy L. Sayers.
He believed that plays in this context ought to be performed in the round, for specific age groups limited in number, with professional actors capable of interacting with the children.
He became a visiting professor in a number of distinguished universities, moving permanently to Canada in 1983 and living in Toronto with his second wife Perri.
The Arts Council of Great Britain established The Children's Award to celebrate the accomplishments and raise the profile of theatre for young people and most especially playwrights who work in this field.
