Jacob Boll (28 May 1828 – 29 September 1880) was a Swiss naturalist and entomologist especially noted for his exploration of the Texas Red Beds. Boll was born 1828 in Würenlos, Switzerland, and educated as a pharmacist in Switzerland and Germany. Established as a naturalist, he turned his attention to microlepidopteraand established contact with Philipp Christoph Zeller. In 1856, his parents and siblings travelled to Texas and joined the La Réunion socialist utopian community. The Bolls left the commune after the first year and established a farm in Dallas near the current Baylor Medical Center. Jacob visited his family in Texas circa 1867, and then returned to Switzerland.
