Frater Albertus Spagyricus (Dr. Albert Richard Riedel, 1911-1984), was founder of the Paracelsus Research Society in Salt Lake City, which later evolved into Paracelsus College. Based on the Paracelsian concept of three essentials, Body, Soul, and Spirit, Frater Albertus developed a system of teaching alchemical concepts using the spagyric technique of separation and cohobation, or repeated distillation. The unique gradated courses allow students to explore aspects of the vegetable, mineral, and animal kingdoms in an understandable and accessible way. Frater Albertus had a profound effect on the way Alchemy and particularly the Spagyric method was disseminated and understood in the mid-to-late 20th century.
