Hartmut Hegeler (born 11 June 1946 in Bremen) is a German Protestant pastor and author, who is committed to rehabilitating the victims of the witch hunts in Europe which reached a peak during the early seventeenth century.
He studied theology in Germany in Bethel, at the university of Marburg and Heidelberg.
Here he made a survey of an irrigation project of the Tamilnad Christian Council by Joseph John and Lüder Lüers.
1976-1982 he was parish pastor in Dortmund, afterwards he worked as a pastor and religious education teacher in a vocational training college in Unna, North Rhine-Westphalia, where he lives.
Questions of his students in 2001 about the persecution of witches were the impulse for his studies on this subject: writing books and holding lectures.
