British jeweller John Houghton Maurice Bonnor (1875-1917) trained as an architectural draughtsman before being taught by Henry Wilson, with whom he forged a lifelong friendship, at the Central School of Arts and Crafts. From 1905, he was head of the metal workshop at the Artificers' Guild before setting up his own metalwork, jewellery and stained glass, mosaic and sculpture studio with his wife, Nancy Agar, in 1908.
