Timothy Lattimore graduated from Central High School (1968), Auburn Community College (1971) and the University of West Virginia (1973). A Republican, he served on the Auburn City Council prior to his election as mayor of Auburn, a position held previously by his father, Paul W. Lattimore. Like his father, Lattimore championed the development of alternative energy sources. He advocated unsuccessfully for the establishment of an Indian casino in the city.
In October 2004, Lattimore and city councilor David Dempsey engaged in a nationally-publicized brawl at city hall. The fisticuffs were an issue in the mayoral campaign of 2008, in which both Lattimore and Dempsey were defeated by former fire chief Michael Quill.
