David Lang was said to be a farmer who lived near Gallatin, Tennessee. On September 23, 1880 he supposedly vanished into thin air while walking through a field near his home. His wife, children, and two men who were passing by in a buggy all witnessed his disappearance.
Frank Edwards included the following description of Lang's disappearance in his book Stranger Than Science (1959):
David Lang had not taken more than half a dozen steps when he disappeared in full view of all those present. Mrs. Lang screamed. The children, too startled to realize what had happened, stood mutely. Instinctively, they all ran toward the spot where Lang had last been seen a few seconds before. Judge Peck and his companion, the Judge's brother-in-law, scrambled out of their buggy and raced across the field. The five of them arrived on the spot of Lang's disappearance almost simultaneously. There was not a tree, not a bush, not a hole to mar the surface. And not a single clue to indicate what had happened to David Lang.
The grownups searched the field around and around, and found nothing. Mrs. Lang became hysterical and had to be led screaming into the house. Meanwhile, neighbors had been altered by the frantic ringing of a huge bell that stood in the side yard, and they spread the alarm. By nightfall scores of people were on the scene, many of them with lanterns. They searched every foot of the field in which Lang had last been seen a few hours before. They stamped their feet on the dry hard sod in hope of detecting some hole into which he might have fallen -- but they found none.
David Lang was gone. He had vanished in full view of his wife, his two children, and the two men in the buggy. One second he was there, walking across the sunlit field, the next instant he was gone.
Eventually the grass around where Lang had disappeared turned yellow in a fifteen-foot diameter circle, suggesting that some form of energy had mysteriously transported him away.
Seven months later his children were said to have heard their father's voice faintly calling out for help as they played near the spot of his disappearance, but eventually the sound of his voice faded away. They never heard his voice again.
