Eric Dingwall endorsed the séance room phenomena of the medium Willi Schneider:
Dingwall rejects the hypothesis of fraud in the sittings and says in the paper:
These are not the words of a skeptic.
And ends his article by stating:
Dingwall was far from a skeptic, he was a full blown paranormal believer.
