Innovation: Wireless Telegraph
Location: St. Louis, Missouri
Year: 1893
By: Nikola Tesla

The wireless telegraph was the next addition to the telegraph.  It worked like radio telegraphy.  Much like the telegraph, it used electrical signaling as communication, but this invention was completely free of wires.  The wireless telegraph worked by transmitting electromagnetic waves from one telegraph to another.  These signals were then translated using the Morse code.
In 1893 in St. Louis, Nikola Tesla gave the first public demonstration of wireless communication and presented his wireless telegraph at the Chicago World’s Fair.  Soon thereafter, many scientists and inventors began playing with this idea of wireless communication.  This idea continues to grow and is still widely used throughout the world .

Innovation: Chicago Ferris Wheel
Location: Chicago, Illinois
Year: 1893
By: George Washington Gale Ferris, Jr.

The original Ferris Wheel was developed by George Washington Gale Ferris, Jr. in 1893.  The wheel was constructed as an attraction for the World’s Columbian Exposition in Chicago, Illinois.  The concept of a spinning wheel with passengers suspended in chairs was first seen in the 17th century in Bulgaria.  Similar wheels began appearing around the world until eventually making its way to America in 1848.  In 1892, William Somers constructed three wooden wheels throughout New Jersey and New York.  George Ferris got the chance to ride on one of these wheels before he designed his own and was sued for patent infringement; however, Ferris successfully proved that the Ferris Wheel differed greatly.  The Ferris Wheel reached a height of 80.4 meters and took about nine minutes to make one revolution.

Innovation: Hennebique System of Reinforced Concrete
Location: France
Year: 1892
By: Francois Hennebique

Francois Hennebique was a French engineer who made a major contribution to the construction industry; he devised a way of strengthening concrete.  This system was designed to withstand the tensile forces against which ordinary concrete is weak.  Hennebique’s idea of strengthening concrete consists of steel reinforcing bars that are embedded within the bottom face of the concrete slab.  The idea of reinforcing concrete originated on a house project in Belgium in 1879 where Hennebique used concrete as a fireproof protection for wrought iron beams.  He patented his reinforced-concrete system in 1892 and the first concrete bridge using this method of reinforcement was built in 1894 in Wiggen, Switzerland.  The Hennebique system of reinforced-concrete has played a huge in role in construction today and is widely used throughout.  `
