Chevalier Worby Beaumont was born in Camberwell, Surrey [now London], England on 27 August 1875 and was the son of the automotive engineer and inventor William Worby Beaumont (1848-1929). He was articled to Eugene Charles Beaumont (1852-1946), with whom he was probably related, in London from 1891 to 1898. He then worked as an assistant to Arthur John Gale (1857-?); to Thomas William Aldwinclke (1843?-1918); and to Herbert Osborn Cresswell (1860-1918) from 1899.
Beaumont qualified as an architect in 1902 and was elected an Associate of the Royal Institute of British Architects (ARIBA) later that year. He subsequently practised as an architect in London. In 1905 he submitted an entry in a competition to design the the Central Library in Hackney, London. His designs are illustrated in British Competitions in Architecture vol. 1, no. 6, January 1906 (p. 19).
His address was given as 100 Palace Road, Lambeth, Surrey [now London] in 1901 and 1902; 17 Buckingham Street, Adelphi, London in 1902; Outer Temple, 222 Strand, London in 1902; 26 Acacia Grove, Dulwich, Surrey [now London] in 1923 and 1933. He died in Dulwich, Surrey on 21 December 1933
