The book also celebrates a galaxy of actors including Flora Robson, John Gielgud, Maggie Smith, Ronnie Barker, Judi Dench and Helena Bonham-Carter and records the first steps of countless students from Peter Brook to Maria Aitken, Diana Quick to Rowan Atkinson, including a few, like Edward Heath and Joanna Trollope, who gained distinction in other spheres.

Most fascinating is the role of the University of Oxford. Using the legal powers invested in Vice Chancellors, Dr Lewis Farnell almost stifled the Playhouse at birth in 1923. And even from 1961 to 1987, when the Playhouse was the University Theatre, Dr Chapman describes its relationship with the University as ‘a shotgun marriage that ended in a messy divorce'.

Since reopening in 1991 following a four-year closure, the theatre has flourished as an independent trust with support from the University, Arts Council England and other donors, staging a varied programme to delight audiences old and new and benefiting in the process from the sea change in academic attitudes to drama.

Thea Shurrock, Rosamund Pike and Holly Kendrick are just three of more recent students who have followed in the footsteps of Michael Palin, Imogen Stubbs and Mel Smith and made names for themselves.
