How did technological innovation impact the United States after the Civil War?



Airbrake invented
George Westinghouse, who would eventually hold more than 400 patents related to railroads and the development of electric power, invents the railroad airbrake and improves it in 1872. The airbrake is a revolutionary advancement in railroad safety and efficiency, making it possible to stop an entire train by pulling just one lever.



Railroads span the continent
The Central Pacific Railroad and the Union Pacific Railroad meet at Promontory Point, Utah, linking the United States by rail from East to West for the first time. In a "golden spike" ceremony on May 10, 1869, the final spike that links the rails is attached to telegraph wires so the blows of the hammer can be heard from coast to coast.

Electricity drives machines
Important advances in our understanding of electricity come from Scottish physicist James Clerk Maxwell, who publishes his Treatise on Electricity and Magnetism and from a 24-year old American physicist, Henry A. Rowland, at Rensselaer Polytechnic Institute in Troy, New York, who explores magnetic fields and alternating current. In Vienna, electricity is used to drive a machine for the first time.



New York installs first electric streetcar
New York City installs an electric streetcar system designed by Stephen Dudley Field. The system is dangerous and ineffective, but it is a sign of major changes to come in urban transportation.

Daily Life


First typewriter marketed
Remington and Sons, a New York gun manufacturing company, markets the first practical typewriter, from an 1868 patent. It has capital letters only. Thomas Edison was granted a patent for an electric typewriter in 1872, but it is not commercially viable until the 1920s. The typewriter quickly changes American office work and provides an opportunity for great numbers of women to enter the work force.



First telephone demonstrated
Scottish-American inventor Alexander Graham Bell, a teacher of the deaf, while experimenting with "electric speech" with telegraph instruments, discovers the properties that lead to the practical development of the telephone. On March 10, 1876, the first sentences uttered over Bell's new telephone are: "Mr. Watson, come here. I want you."



Armour and Swift begin Chicago meatpacking



Refrigerated railroad cars developed
Refrigerated railroad cars, primarily box cars packed with ice, are in regular use to ship meat from Chicago Stockyards to markets in the East. In 1878 meat packer Gustavus Swift hires a Boston engineer, Andrew Chase, to develop an improved refrigerated car. The refrigerated car greatly expands markets for perishable products.

Inventions showcased at Centennial Exposition
American inventions are showcased at the U.S. Centennial Exposition in Philadelphia. Among more than 8,000 machines displayed are Remington's typewriter and Bell's telephone. A giant Corliss Steam Engine symbolizes the steam power of the age. Visitors at the Centennial Exposition learn via telegraph that Colonel George Armstrong Custer has been killed fighting Indians at the Little Big Horn.

Westinghouse develops AC electric power
George Westinghouse pioneers in the development of electrical transformers. Westinghouse is the major developer of alternating current (AC) electric power. Edison's early uses of electricity used direct current (DC). Alternating current can travel over much longer distances than direct current and make it possible to rapidly expand electric service to individual homes.

Priced at $25, the camera takes one hundred pictures, but has to be returned to Eastman's firm in Rochester, New York, for processing and the loading of a new roll of film.



Motion picture projector invented
Thomas Edison invents the kinetoscope, which displays motion by showing a rapid succession of single images on 35 mm perforated celluloid film.
