Knox was born in Adelaide, the eldest son of John Knox, jun, ( – 27 October 1908) and his wife Eliza Annie Nairn Knox, née Morton ( – 7 December 1915) of "Kirkwall", William Street, Norwood.[1]
He was a student of fellow Australian composer Paolo Giorza[2]
He began in 1912 the tradition of free Sunday morning organ recitals at the Adelaide Town Hall.[4]Louis Yemm deputised for him in July and August 1912.[5]
Knox followed T. H. Jones as City Organist in 1923 and served until 1928. The appointment of his successor was attended by controversy: John Dempster was appointed without any competitive evaluation, and eminent musicians John Horner, Frederic Finlay and W. Lawrence Haggitt, who had all applied, signed a public letter airing their sense of injustice, clearly implying he was a poor choice.[6] Knox refrained from comment.
He died after a short illness and his remains were interred in the West Terrace Cemetery.
An obituary photograph of Knox was published wearing starched collar and magnificent whiskers.[7]
His sister Ada Knox (1875–1963) was a well-known singer who was frequently accompanied by her brother on piano. She married Edgar Charles Thurston on 14 September 1912.[8]
His uncle, Nathaniel Alexander Knox (1837 – 6 March 1908) was a partner in the legal firm Knox, Gwynne and Hargrave with E C Gwynne (c. 1848 – 19 August 1905) and C T Hargrave (1855 – 9 September 1924). He founded the suburb Knoxville (now subsumed in the suburbs of Glenside and Glenunga).[9]
