NuTone™ founded National Doorbell Day to celebrate the innovative development of the first melodious door chime invented by J.Ralph Corbett during the Great Depression. His invention replaced the buzzers and knockers that often alerted residents to visitors. Today, NuTone is proud to announce the launch of NuTone Knock™, the company’s revolutionary new video doorbell that allows homeowners to see and talk to visitors from anywhere in the world using their smartphone.
The Registrar at National Day Calendar® proclaimed the day to be observed annually beginning in 2017.
