Elmo's history begins in 1870 when the Texas and Pacific Railway laid track through the area. A community sprang up at the railhead, and it was decided that the new town be named to honor Elmo Scott, a T&P Railroad surveyor. Elmo received a post office in 1873 and by the mid-1880s possessed several mills, five churches, its own schools and approximately 900 residents. Through the remainder of the 19th century, however, the population fell and by 1945 only 150 people called Elmo home. By 1990 this figure had fallen to 90; it remained at this level through to the 2000 Census.[3]
In 1892, Elmo residents adopted a resolution declaring a sundown town, prohibiting African Americans from living there and forcing existing black residents to leave.[4]
