The father of radio, but he also was involved in very strange research on earth energy. He appears to have invented a telephone that was able to transmit through the ground. He had been dead for about a week in the middle of winter when the neighbors asked the sheriff to break down the door. The odd thing was his home was still warm even though it had been snowing for weeks. The sheriff traced the heat source to 2 round copper plates spaced a couple of inches apart and leading to 2 wires which were attached to grounding rods under the sink. Of course, all of his equipment from his farm disappeared very quickly and has not been heard of since. Another odd scientist is John Keeley. His work with vibratory physics is landmark, though most of his work was 'removed' as soon as he passed on. Good luck, HGM
