South Houston

C.S. Woods of the Western Land Company founded the settlement of Dumont in 1907. A post office appeared in 1910. In 1913 Dumont was incorporated as the city of South Houston. Because of the 1913 incorporation, Houston did not incorporate South Houston's territory into its city limits, while Houston annexed surrounding areas that were unincorporated. South Houston's initial industrial activity consisted of shipping produce along the Galveston, Houston and Henderson Railroad. The hurricane of 1915 destroyed many of the local industries. The establishment of the Houston Ship Channel resulted in the establishment of manufacturing industries inland, including in South Houston. Between the 1940s and the early 1960s South Houston found rapid population growth. The city had 7,523 inhabitants in 1960. In 1980 South Houston had 11,782 inhabitants and 303 businesses. In 1990 14,207 inhabitants lived in South Houston.
