One of the first steam sawmills in Texas was planned in 1829 by John Richardson Harris, founder of Harrisburg (part of modern Houston). It operated until at least 1833. After the Texas Revolution, the influx of settlers quickly increased demand for lumber. Sawmills were constructed on the coast in locations such as Galveston, Houston, and Beaumont. As settlement moved further inland new mills were constructed at towns from Nacodoches to Bastrop.
