Inventions Change the Nation

The Patent Office had never seen a year like 1897. An average of 60 patents were being granted everyday. By years end, Americans had registered some 21,000 patents. This was more than the total recorded in the entire 1850’s.

Patent – license for a new invention

•The Wright brother’s experiment with the “flying machine.” Surprising, people were not too interested at first. It was the United States military that first recognized a practical use for their new discovery.

•Cyrus Field laid an underwater cable that transmitted telegraph messages from North America to Europe. This led to A.G. Bell’s discovery of the “talking machine” which we call the telephone.

•Thomas Edison was the master of many inventions: motion picture projector, electric power plant, phonograph, incandescent light bulb. He became known as the “Wizard of Menlo Park” because he systemized the process of creating inventions.

•Henry Ford revolutionized automobile production with the assembly line. This made it possible for millions of Americans to afford cars.

•Other important inventions such as the telegraph, the transatlantic telegraph cable, and the telephone were important to businesses after 1850 because they filled a need that other inventions of the day could not. Businesses that thrived on shipping overseas really benefited.
