Dan was born in Poteet, Texas, but has been a resident of the Greater Houston area for most of his life. A retired Shell Oil geologist with experience in various research, exploration and management roles, he holds a Bachelor’s Degree from Rice University, a Master's in Teaching from Northwestern University, a Master of Arts in Geology from the University of Wyoming, and a PhD in Geology from the University of Texas at Austin.

In retirement, he has augmented his earlier geologic publications with a  a number of books on the social history and usage of the concertina, a Victorian musical instrument that has gained favor in traditional music circles in recent years. This is his first publication on Texas history.

Dan Worrall is a member of the Harris County Historical Commission, working since 2014 on a project to bring historical markers to significant sites in western Harris County. He is also a director of the Morse-Bragg Cemetery Association, and worked to save and protect that nineteenth-century graveyard in the Uptown area from development. That task has recently been accomplished, and the cemetery, replete with a granite obelisk and a soon-to-be-installed Harris County historical marker, is now a Harris County Precinct 3 park. Dan is one of a fifth generation of his family to live in the Houston area, and some of his ancestors could be found at Pleasant Bend, Piney Point, and Wheaton’s Ford along the San Felipe Trail, among other places.  He appeared on the recent PBS documentary, Post Oak Boulevard: A Texas Legacy, along with several of the maps and illustrations from his book, Pleasant Bend.
