According to historian Samuel T. Wiley, no major buildings had been erected, by 1844, on the land that would eventually become the borough of Tremont, while historians Adolf Schalck and David Henning stated that a concerted settlement effort began here sometime that year, "stimulated by the extensive coal developments in the vicinity."
Within four years, the Tremont Iron Works had been established by Umholtz & Lentz (1847) and a new post office had been established there (1848) with John B. Zeibach serving as its first postmaster. The first National Bank of Tremont subsequently opened its doors in 1865.
