"...there is a reason garbage trucks look the way they do, and they were revolutionized by a man who was a politician, businessman and inventor... George Roby Dempster.
"Dempster was from Knoxville, Tenn. and a businessman who made his mark in construction and road building before the Great Depression wiped him out. With a background in stuff that required heavy machinery, though, Dempster knew how much labor was required in hauling stuff. He saw garbage trucks of the time and the amount of effort needed for men to throw things into the bed of a truck."
