John Christopher Williams AO OBE (born 24 April 1941) is an Australian-born classical guitarist renowned for his ensemble playing as well as his interpretation and promotion of the modern classical guitar repertoire. In 1973, he shared a Grammy Award in the Best Chamber Music Performance category with fellow guitarist Julian Bream for Together (released in the US as Julian and John (Works by Lawes, Carulli, Albéniz, Granados)). Guitar historian Graham Wade has said that “John is perhaps the most technically accomplished guitarist the world has seen.”

John Williams is an only child who was born on 24 April 1941 in Melbourne to an English father, Len Williams, who bought John, at age four, his first guitar with a modified neck. Len would later found the Spanish Guitar Centre in London, England. John’s mother Melaan (née Ah Ket) was the daughter of William Ah Ket, the first Australian barrister of Chinese heritage. In 1952, the family moved to England, where John attended Friern Barnet Grammar School, London.

Williams was initially taught guitar by his father, who was a musically disciplined and accomplished classical guitarist. From the age of 11, Williams attended summer courses with Andrés Segovia at the Accademia Musicale Chigiana in Siena, Italy. He attended the Royal College of Music in London, from 1956 to 1959, studying piano because the college did not have a guitar section. In 1958, when he was 17 years old, he made his musical debut performing publicly at London’s Wigmore Hall. Upon graduating from his college, he was invited to create and then to run their guitar department for its first two years of life. Williams maintains links with the college (and also with the Royal Northern College of Music in Manchester).
