The Las Vegas Sun reports Thomas J. Huddleston died in Poulsbo, Wash., after a lengthy illness. He was 69.
Huddleston was state fire marshal from 1977 to 1987, and pushed for the first statewide fire and building code.
The November 1980 fire at the MGM killed 87 people. In February 1981, eight people died in a fire at the Las Vegas Hilton.
Those tragedies resulted in the Legislature enacting tough safety codes requiring sprinklers in large buildings.
After Nevada, Huddleston was fire marshal for Corona, Calif. until 1993. He then joined the Poulsbo Fire Department, became deputy chief in 2005 and retired in 2010.
