In 1908 or 1909, a town site was surveyed by C.F.H. Von Bulcher. Halderman named the new community "Premont", after Seeligson Ranch foreman Charles Premont. A section of the community, located east of the railroad, was set aside for Mexican and Mexican-American families. A plaza called Hidalgo Park was designed and built to serve those families. R.P. Halderman sold hundreds of lots to Charles Premont, who in turn served as the real estate agent for the Mexican families, as he was fluent in Spanish. He also donated the funds to build Santa Theresa Catholic Church, a Roman Catholic institution that now ministers to three missions. Several businesses, including a post office and a general store owned by Andrés Canales, opened in the community during its early years. Premont became part of the newly organized Jim Wells County on March 11, 1911. In an election held on May 6, 1911, Charles Premont was elected as the county's first commissioner. By 1912, Premont had ten businesses and an estimated population of 800. That figure had risen to approximately 1,000 by 1914, the same year that the San Antonio and Aransas Pass Railway built a stop at Premont. The Premont Independent School District was created in 1921. At the time of its creation, Premont ISD was the largest school district in Jim Wells County. Premont's population had declined to roughly 600 by 1925.
