Pilgram, Wilhelm
Wilhelm Pilgram (1934- ) is a German doctor of medicine by profession, but he is also a keen student of catastrophism. This led him to follow the views of the Tollmanns and consequently he supports the idea of Atlantis situated on the Mid Atlantic Ridge and destroyed around 10,000 years ago by the impact of a comet(a).
