John Christopher Williams AO OBE (born 24 April 1941) is an Australian virtuosic 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 Performancecategory 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 was born on 24 April 1941 in Melbourne, Australia, to an English father, Len Williams, who later founded the Spanish Guitar Centre in London, and Malaan (née Ah Ket), a daughter of Melbourne barrister William Ah Ket. In 1952, the family moved to England where he attended Friern Barnet Grammar School, London. Williams was initially taught guitar by his father, who was an accomplished guitarist. From the age of 11, Williams attended summer courses with Andrés Segovia at the Accademia Musicale Chigiana in Siena, Italy. Later, he attended the Royal College of Music in London, from 1956 to 1959, studying piano because the college did not have a guitar department at the time. Upon graduation, he was invited to create such a department. He took the opportunity and ran the department for its first two years. Williams has maintained links with the college (and with the Royal Northern College of Music in Manchester) ever since.
