Bob Campbell AKA 'Stig' (born 1963) is a self taught English sculptor. He is best known for his furniture design and his use of redundant mechanical and industrial parts. His home and workshop are located in South Yorkshire, a region of England that was traditionally a centre for heavy engineering and steel production. The area experienced a dramatic decline in fortunes from the 1980's onwards and this is evident in both the forms and materials he works with.

Throughout his career Bob has retained a tight control of how his work is exhibited. Previous venues have ranged wildly from upmarket retailers to music festivals, street markets, and a small private gallery attached to his workshop. Bob is fiercely independent and his rejection of a conventional art sales model is a key part of who he is and why he has attracted the support of a moderately sized and dedicated group of private collectors across the UK. These people often find entirely disparate meanings within his work.
