State Representative Dan Kubiak was born in Reagan in 1938. He served from three House districts between 1969 and 1983 and again from 1991 until his death in 1998. Kubiak's younger brother, L. B. Kubiak, is a veterinarian in Austin and a Rockdale resident who from 1983 to 1991 held the same House seat.
Reagan was established in 1873, shortly after the Waco and Northwestern Railroad completed the section of track between Bremond and Ross. A post office opened that year, as well, and was named for William Reason Reagan who donated the land for the townsite.
Transitioning from a rail stop to agriculture during the 20th century Reagan saw most of its businesses move to the nearby county seat of Marlin. Current residents commute to nearby cities where they are employed in non-agricultural professions. Farming and ranching are still practiced but the majority of income is derived from other sources.
The population grew to 500 by the 1890s, and reached a high of 600 in 1914. Despite the small population and being an unincorporated community, Reagan is the home to the Texas Pneumatic Tools Company.
