Knox A. Thomas purchased a lot from the John C. Ryan Land Co. in November 1923. His house was completed the following year. It is a substantial two-story brick structure with hipped roof and full front porch. The proportions of the brick porch piers and roof brackets reinforce the house’s feeling of massiveness. Thomas was manager of Medcalf & Thomas, a supplier of surgical instruments, as well as vice president of John L. Ashe, Inc., a men’s shoe store. The house remained in the family until 1976. The Thomas House was designated a City of Fort Worth Historic and Cultural Landmark in 1993.
