Dr. John Raleigh Briggs (1851–1907) was the first to draw scientific attention of the Western scientific world to peyote.  Louis Lewin described Anhalonium lewinii in 1888.  Arthur Heffter conducted self experiments on its effects in 1897.  Similarly, Norwegian ethnographer Carl Sofus Lumholtz  studied and wrote about the use of peyote among the Indians of Mexico. Lumholtz also reported that, lacking other intoxicants, Texas Rangers captured by Union forces during the American Civil War soaked peyote buttons in water and became "intoxicated with the liquid".  Arguably, this is the first documented use of peyote by non-Native Americans.
