So many of Dayton’s inventions have become common in our daily lives. Vincent G. Apple brought electricity to rural homes; Dr. William H. Charch invented cellophane; E.R. Churchwell, working in the Biltmore Hotel, developed the first collapsible baby crib. The ice cube tray is another such invention. Arthur Frei, working at Frigidaire, developed 23 patents on the ice cube tray. One of his most significant developments was the quick release lever on top of the tray that dislodged the cubes. Prior to that, the metal tray had to be soaked in hot water to free the ice.
