Simpson Building. After serving as manager of the Cameron lumberyard in Quanah and then as a general manager in Waco, L. Simpson began his own lumber company and returned to Quanah in 1906. In 1910, Simpson had this three-story commercial building constructed to house his offices; other local businesses, including the corner drug store from 1920 until 1998; and the elks lodge, which occupied the top floor. Featuring decorative brick detailing and a corner entry, the Simpson building is a significant part of Quanah's architectural heritage. Recorded Texas Historic Landmark - 2001 #12594
