This history of Spencer traces its industrial rise through wire and shoe manufacturing, evolving transit, population growth, and ongoing revitalization efforts.By the mid-nineteenth century, Spencer was beginning its 100-year progression in the wire and shoe business. The railroad arrived in 1879, opening new markets. Trolleys arrived in 1891 to aid workers' transportation needs. These improvements in transportation helped to fuel the expansion of both industries, which were so significant in the town's history. Population growth followed this expansion of jobs, rising from 2,777 in 1860 to 7,627 in 1900. Dairy farms were prevalent during this time, but the mid-twentieth century brought the demise of many farms. The school system had expanded greatly with many multi-room brick schools being built before the close of the nineteenth century. Today, the population is approximately 12,000. The shoe and wire industries have long disappeared, and Flexcon Company stands as the town's largest employer. As of this writing, Main Street is undergoing a major modernization, which will hopefully spur even more renovation for a town rich in history and ready for renewal.
