As a result of its reputation for being haunted, the house stood empty for several years before undergoing its second remodeling to ready it for housing emigrant Equitable Gas Company workers. These workers experienced many strange occurrences but wrote them off as pranks by the American workers they had replaced (for lower wages). One night things took a tragic turn, however, and two of the workers were found dead in the basement. One had a board driven like a stake through his chest, and the other was hanging from a rafter. These men had both been seen alive just minutes earlier.
In 1920, the famous scientist and inventor, Thomas Edison, came to study the house. Edison spoke of a machine that he was building to allow communication with the dead. Edison died before the mechanism was perfected. Winer and Osborn wrote that Thomas Edison's visit to the house at 1129 Ridge Avenue apparently influenced his strong belief in the afterlife.
