Olaf Danielson was born and raised in the small northwestern Wisconsin town of Falun, a town named for Falun, Sweden, where all of the first settlers originated. Olaf grew up amid the stories and folklore of Sweden, and some of that folklore can be found in his Defenders of the Earth Series. His interests in world history, bird watching, and travel have guided him on a somewhat nomadic lifestyle that greatly enhance his stories.
Olaf attended Ripon College, where he graduated summa cum laude, and received his doctorate at the University of Minnesota. Licensed to practice medicine in five states, Olaf now runs a successful emergency room staffing business. He currently lives in the northeastern South Dakota town of Milbank with his very tolerant wife, three children, and a house full of pets.
