Carl Frederick von Roemer

Born in 1818 in the Kingdom of Hanover, von Roemer toured Texas from 1845 to 1847, traveling from Galveston to Fredericksburg and north to Waco. He had wide interests: while chiefly a geologist, stratigrapher and paleontologist, von Roemer did meaningful work in Texas on botany and landscape-scale ecology. He provided a systematic geologic survey of the state, but also reported on the dominant vegetation types (prairies, woodlands, riverline forests), noted ecotones where habitats transitioned, and described conspicuous plants (live oaks, mesquite, cacti, and grasses). From a conservation standpoint, he laid down some cautionary notes on the limits of soil fertility and reliable water supplies. Much of his account of Texas is found in Texas: With Particular Reference to German Emigration (1849), including his natural history notes, travel log, and a guide for German settlers. That work was followed by a geological monograph, perhaps the first for Texas: The Cretaceous Formations of Texas and their Organic Inclusions (1852).
