John K. Allen, who with his brother Augustus founded the town named for the hero of San Jacinto, succumbed to yellow fever on August 18, 1838 at the age of 28. Not exactly a ringing endorsement of the health benefits of living in Houston!
The New Yorkers were such enthusiastic supporters of the Texas Revolution that they bought and equipped a ship to guard the coast against the Mexican navy. Augustus Allen, the older brother by four years, outlived John by a quarter century and had the good taste to die somewhere other than Houston.
