Leland C. Wyman, an outstanding authority on Navajo religion, extended the research of his scholarship from his primary field of physiology to anthropology and art, folklore, and folk literature. Wyman, a Ph.D., in Biology from Harvard, taught and did research in physiology at Boston University for four decades, meanwhile engaging in many cross-disciplinary projects. In the early 1930s he began to write on Navajo ceremonialism and mythology, and soon teamed up with anthropologists and other specialists to publish on Navajo medicine, ethnobotany, ethnoentomology, psychology, and art.
