Bruce "Duke" Seifried (August 19, 1935 in Janesville, Wisconsin – September 29, 2018[1]) was a maker of Miniature models for games.
Shannon Appelcline noted that "Seifried requires a bit of additional attention, as he's one of the most influential people in the early hobbyist miniatures market.
More importantly for the RPG industry, he came up with the phrase 'adventure gaming' — which was used to differentiate RPGs from 'wargaming' in the earliest days of the hobby.
"[2]: 305 Jim Oden of Heritage Models and Seifried both experienced cashflow problems with their companies in January 1977, so they agreed to merge Custom Cast and The Royal Guardsman retail store which Oden founded in 1974, into Heritage Models, and Seifried moved to Dallas in support of the newly merged company.
[2]: 310 Seifried left Heritage in early 1982 and went to work for TSR, which wanted to start their own miniatures manufacturing.
