Dr. Willy Seppel
Background
Dr. Willy Seppel is a bio-physicist who works at Argon Laboratories in Ann Arbor, Michigan.
During the events of The Cremators (1973) played by Eric Sinclair
Dr. Seppel arrives at Dr. Ian Thorne's light house and asks where he found the rock crystals. Dr. Seppel tells him the rock crystals give off infrared and almost have an intellect. Ian shows Dr. Seppel the container he held the rock crystals in and how it was melted and tells him he thinks the rock crystals are connected to people's deaths. Ian suggests they keep the rock crystal in a pail of ice, but Dr. Seppel tells him the pail would melt before the ice did if it decided to radiate heat. The next day, Ian, Dr. Seppel and Pete are outside and Ian brings up the story of the Dune Roller that would wake up every hundred years and rolled a path of destruction. Ian then tells Pete that he thinks Phil and George were killed by the Dune Roller. Pete then tells Ian and Dr. Seppel that Mrs. Lacy saw some lights in the sky the other night. Mrs. Lacy tells Ian, Dr. Seppel and Pete that she saw something which she thinks might have been hippies around her place holding lights. Ian tells Dr. Seppel he thinks the Cremator fell to Earth years ago and is collecting its rock crystal children like a mother. Ian and Dr. Seppel go to the hospital after Jeannie is injured by the Cremator and Dr. Seppel introduces Cunningham to Ian. Cunningham tells them Jeannie was heading to the middle of the lake when they found her. Ian claps his hands and they glow. Dr. Seppel then slaps his hands together and they also glow. Ian then tells Dr. Seppel he is worried the Cremator will come and attack anyone that has touched the rock crystals. Dr. Seppel goes to Cunningham and tells him he is worried about Ian and asks him to help Ian, but Cunningham refuses to help. During the night Dr. Seppel goes out on a boat with a jar holding three rock crystals. They start to glow and the Cremator appears out of the water. Dr. Seppel shoots at it with a shotgun, but it kills him.
