The community's history dates back to the 1920s, when Scottish immigrant John Kennedy established Globe Laboratories, Inc. to produce serum to immunize cattle against blackleg, a disease that affected calves under two years of age. About ten years later, he sold the company to his partner. Kennedy later purchased 400 acres (1.6 km2) of land in an area bordered by East McLeroy Boulevard on the north and FM 156 (Blue Mound Road) to the east. His interest in aircraft led him to create the Globe Aircraft Company. As his operation grew, more and more people began to settle near his plant. The settlement was initially known as Saginaw Park, but later took the name Blue Mound after a nearby hill. During the 1950s, Bell Helicopter used the Kennedy facility to develop its new helicopters, but the company left the facility in 1960.
