Samuel Belfrage

 was the owner of the Brass Mill where Thomas Brewster worked. He was absent most of the time. His factory had more accidents than the rest of the country. He wasn't concerned about how quickly the Sixth Doctor and Evelyn Smythe managed to get from Ackleton to Liverpool, even though he took the only train. He used a patch to make him look human. He was in the illegal trade of selling hallite to other worlds. He accidently set a piece of valvadis technology which created living machines. (AUDIO: Industrial Evolution)
