Denis Mann (born 1935) is a Scottish glass artist. He studied under Helen Monro Turner at the Edinburgh Art College where he learnt the copper wheel engraving technique, which he used in his later career. After a short stint as an art teacher, including during National Service with the Royal Air Force, Mann became a professional artist. Mann sent several pieces of work to Caithness Glass, ahead of accepting a job there as engraver and designer, and these were spotted by Bill Wright, creator and producer of upcoming BBC game show Mastermind. Wright asked Mann to produce the trophies for the show. The first of these was presented in 1972 and Mann went on to produce them for each subsequent series. He is now semi-retired.
