About this Collection
Some of the most popular exhibits at the Fair demonstrated the sending of messages over land and water without using any wires.
The new invention of wireless telegraphy was attracting lots of interest at the turn of the century. The Fair would be remembered as the first one to demonstrate the growing potential of this new technology.
Fair-goers watched messages being sent and received at exhibits in several of the palaces. Or, while walking around the Fairgrounds they could see the seven wireless telegraph stations operated by the DeForest Wireless Telegraph Company.
Lee DeForest the mastermind behind the stations received the grand prize medal for general excellence in wireless telegraphy on Electricity Day.
The largest of the Deforest wireless towers appears in the background of this picture. After an exciting ride to the top of this 300-foot tower, fairgoers would watch the operator inside an office at the top as he sent messages to Chicago over 300 miles away. Daily messages were also sent from this tower to two St. Louis afternoon newspapers detailing Fair activities.
Even fair-goers who were not interested in this new wireless technology enjoyed riding the elevators to the top of the tower and getting an exciting view of the Fairgrounds and much of St. Louis City and County.
