What stands out about Conroe’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The city is named after Isaac Conroe. Born in the North, he served as a Union Cavalry officer and settled in Houston after the Civil War. There he became a lumberman. Conroe founded a sawmill in this area in 1881. The community built its early economy and wealth on the lumber industry. Originally named "Conroe's Switch", the community received an influx of workers and residents in the late 19th century who were attracted to the growth of the lumber industry, which harvested the local piney wood forest.
In 1886, Conroe Mill School was established in the expanding town. Conroe Normal and Industrial College, a school for African Americans, served the area.
