Norman Emerick of Fisher-Price
It is believed that the first baby monitor was made in the 1930's by a man named Norman Emerick of Fisher-Price. The baby monitor was invented after an incident wherein Charles Lindbergh's 20 month old baby was kidnapped. The first baby monitor worked by using radio waves to transmit sound waves from one room to another.
