Almost two decades after his death Walton's reputation is higher than ever - many of his masterworks remain firm favourites in the concert repertoire, notably his eloquent concertos for violin, viola and cello, his dramatic cantata Belshazzar's Feast, his vivid film scores (such as Henry V), his powerful First Symphony (the creative outcome of a tempestuous love affair) and the sparkling entertainment Facade, a brilliant divertissement based on Edith Sitwell's poems and composed before he was twenty.
Born in the cotton town of Oldham, young Billie's life was transformed when he won a boy chorister's scholarship to Christ Church, Oxford.
He soon lost his Lancashire accent but never his innate canniness.
His remarkable creative gifts were spotted early both by Hubert Parry (of "Jerusalem" fame) and the intellectually adventurous circle surrounding the Sitwell family, who persuaded him, since he was determined not to return to the narrow confines of life in Oldham, that he should quit Oxford without a degree to live with them in Jazz-Age London and earn his living purely as a composer.He stuck to music but it made him only a pittance, however, and he became a self-acknowledged scrounger, lodging with the Sitwells for over ten years.
His evident genius and his romantic good looks saw him taken up by rich admirers such as the poet Siegfried Sassoon and the rich industrialist Samuel Corutauld, to whose mistress, Christabel Aberconway, he dedicated his first orchestral masterpiece, the 1929 Viola Concerto.
His idyllic relationship with a beautiful but impecunious German princess ended in an emotional turmoil that held up completion of his First Symphony for over a year.
Walton then became the lover of a woman 22 years his senior, Alice, Viscountess Wimborne, a powerful society hostess who guided his career and chose the librettist, Christopher Hassall, for his first opera Troilus and Cressida.
Within a year of her death in 1948 (when he was 46) he met the vivacous 22 year old Susana Gil Passo and they married after a whirlwind courtship.
On their honeymoon he announced that he did not want children and intended to live in Italy.They settled on the island of Ischia in the Bay of Naples, eventually acquiring a plot of rocky hillside land upon which they developed the villas and estate of La Mortella, now one of Italy's best-known gardens.
A professional composer to his fingertips, always writing to commission, Walton's critical reputation sagged during his self-imposed Italian exile.
But he demonstrated an uncanny flair for tapping a patriotic vein in such popular works as Crown Imperial, Orb and Sceptre and the Coronation Te Deum.
A knighthood awarded in 1951 was followed by other honours, notably the Order of Merit.
His final years were dogged by ill health - including a near fatal attack of lung cancer - and by a depressing sense of creative impotence; lack of inspiration forced him to abandon plans in his seventies to compose a Third Symphony.
The authors Humphrey Burton and Maureen Murray worked with Walton on Ischia and have retained their Waltonian links since his death in 1983: she is curator of the Walton Archive and he is a member of the Walton Trust.
With their shared background in television documentary they have adopted a filmic approach to this new pictorial biography.Each of its eight chapters opens with a succinct descriptive essay highlighting Walton's life and his significant musical achievements: the narrative text is followed by many pages of illustrations, in which portraits by Cecil Beaton, Bill Brandt, Norman Parkinson and many others are interspersed with hitherto unpublished family photographs, music manuscript, press cuttings, playbills etc., all accompanied by commentary, reminiscences, anecdotes and liberal quotations from Walton's typically trenchant letters and self-deprecating interviews for radio and television.
Much more than a coffee-table book, this centenary tribute conveys the essence of Walton's personality and provides a measure of his colossal artistic achievement.
It will be essential reading for all lovers of his music and students of twentieth century musical life.
