History Tour Stop

“T.M. Callahan was born 1857 in Chillicothe, Illinois. He was trained as a teacher and an itinerant photographer who loved to travel. He fell in love with and married Alice Barnett, a banker’s daughter, in Humansville, Missouri in 1886.

Together they moved west to Longmont in 1889 where they opened a small dry goods store on Main Street called “The Golden Rule.

As his business prospered he expanded into general merchandise, with Alice by his side and often in the lead making tasteful and stylish product choices. T.M. Callahan opened multiple “The Golden Rule” stores throughout the Rocky Mountain and Pacific Coast states where his well-trained Longmont clerks became managers. J.C. Penney took a job with Callahan from 1899 to 1907 after Penney’s butcher shop failed. In partnership they opened a store in Kemmerer, Wyo., which would later become one of Penney’s chain stores. The first store under the J.C. Penney name was in Longmont, Colo.

In 1938, the Callahans moved to Nevada to be near their son. They gifted their house and garden to the City of Longmont. ” – City of Longmont Community Services
