Hans Sebald was Professor of Sociology at Arizona State University.
Sebald taught courses in the sociology of youth and social psychology, but was perhaps best known for his work on witchcraft.
He was born in Selb, Germany, but came to the United States in 1954 to attend Manchester University in Indiana, from which he received a bachelor's degree cum laude in 1958.
Sebald frequently spent summers doing research on witchcraft in Bavarian Switzerland, where a grandmother had been a practicing witch.
Sebald was a member of the Phoenix Skeptics, and spoke to that group about witchcraft on a number of occasions.
