Seat heaters were a well-respected job in old drafty castles. Royalty would hire both men and women who were particularly thick and have them sit in chairs ahead of arrival into that room. This was especially useful for banquets as they would serve as a seat holder, allowing the nobles to arrive fashionably late and still have a good spot for dinner. In the late 1890s, William Hoskins invented the heating coil, which caused mass unemployment in this industry.
