Joseph Lockwood was born in poverty next to his grandfather's mill in Southwell Nottinghamshire; from there he went on to become a world expert and author of the standard textbook on flour milling.
In mid-life he turned from managing and designing flour mills to becoming Chairman of EMI, 'The Greatest Recording Organisation in the World'.
A much sought after public figure, businessman and government advisor, he played a major role in building the National Theatre, restoring the Royal Opera House, as well as sitting on the Arts Council and becoming Chairman of the Royal Ballet.
For twenty years his good friend William Cavendish worked alongside Sir Joe, as he was always known, when Sir Joe was the Chairman of EMI, and the last record company to remain in British ownership.
This book is the story of how this relationship developed, as Sir Joe's prestige brought him ever increasing influence in industry and the arts, while William remained by his side, quietly observing in the background.
