Thomas Edison

Thomas Edison (1847-1931) was an inventor and businessman. In 1879, a light bulb went off in his head that led to one of his greatest inventions.

Alexander Graham Bell (1847-1922)

Edwin L. Drake

In 1878, Edison focused on inventing a safe, inexpensive electric light to replace the gaslight–a challenge that scientists had been grappling with for the last 50 years. With financial help from J.P. Morgan and the Vanderbilt family, Edison set up the Edison Electric Light Company and began research and development. He made a breakthrough in October 1879 with a bulb that used a platinum filament, and in the summer of 1880 discovered carbonized bamboo as a viable alternative for the filament, which proved to be the key to a long-lasting and affordable light bulb. In 1881, he set up an electric light company in Newark.

In 1876, a little bell rang in his head.

Alexander Graham Bell was a scientist, inventor, engineer, and innovator. Bell is credited with inventing the first practical telephone in 1876.

Edwin Laurentine Drake (1819-1880) was the driller of the first productive oil well in the United States. In the late 1850s, a man named James Townsend hired Drake to investigate Titusville, Pennsylvania for oil deposits. Drake had a vision...

-ION

Invention- a new, useful process, machine, improvement, etc., that did not exist before.

Drake innovated the solution to drive an iron pipe down into the bedrock, then place a drill inside the pipe to keep water out of the excavated shaft. In 1859, his invention succeeded and he struck oil.

The Bessemer Process

William Le Baron Jenney

Inventions of the Gilded Age

The first inexpensive industrial process for mass production of steel from molten pig iron. The main thing it does is remove impurities from the iron through oxyidation (air blowing through the iron).

William Le Baron Jenney (1832-1907) is famous for his large commerical buildings and helping to launch the Chicago School of architecture and pioneered skyscraper design.

Industrial Pollution

by Sophie Austin and Sophie Gershtenson

Industrial pollution is the contamination of the environment by business, particularly plants and factories, that dump waste into the air and water.

  • The 1879 Leiter building used the popular cast iron and masonry to support large exterior openings filled with glass.Natural light was an important element in Jenney's tall buildings.
  • The Home Insurance Building in Chicago was one of the first buildings to use a new metal, steel, as a skeleton for support. It became the standard for American skyscraper design.
  • Jenney's skeleton-frame Manhattan Building was the first to achieve a height of 16 stories.
  • His Horticultural Building was the largest botanical conservatory ever built.

Christopher Sholes

Helped invent the typewriter and came up with the...

keyboard.

He arranged the most used letters farther apart from each other to prevent jamming of the keys.
