George Edward "Dad" or "Ed" Lemmon (1857–1945) was among the elite cattlemen at the turn of the 20th century. Lemmon is credited with starting the Western South Dakota Stockgrowers Association, helping the Chicago Milwaukee & St. Paul Railroad – a predecessor of Chicago, Milwaukee, St. Paul and Pacific Railroad – through South Dakota, and founding a town along that railroad named Lemmon, South Dakota. He was also a prolific writer who preserved a firsthand account of the history of the western United States.
