A TECHNOLOGICAL REVOLUTION

TECHNOLOGICAL REVOLUTIONTechnology drastically changed

people’s daily livesStarted a movement away from

agrarian living to urbanization-especially in the north

TECHNOLOGICAL ADVANCES AND CHANGES

Samuel Morse 1844-sent the first

telegraph message Marked the

beginning of a second industrial revolution

“What Hath God Wrought”

DAILY LIFE PRIOR TO REVOLUTION No indoor electric

lighting Candles Whale oil No ice Very slow

communications

Investing in Technology Patents

Licenses that give an inventor the exclusive right to make, use, or sell an invention for a set period of time

Between 1790 and 1860, 36000 patents were issued

In contrast, 500,000 issued between 1860 and 1890

Growth of business due to investments in patents.

Led to massive increase in productivity-the amount of goods and services created in a given period of time

DRAKE AND EDISON

DRAKE AND EDISON Edwin L. Drake

Sent to drill for oil in 1858

Titusville, Pennsylvania

New method to get oil quicker

Led to several boomtowns

Kerosene Gasoline

Thomas Edison Inventor

Several inventions including the phonograph and light bulb

Finally found filament from bamboo fiber

Also came up with idea of central power station-built power plant in NYC

Idea spread across country

LEWIS LATIMER AND WESTINGHOUSE IMPROVE ELECTRICITYLewis Latimer

Improved method for producing filaments in light bulbs

George WestinghouseAlternating

current- cheaper and could travel longer distance

Transformer-made home use of electricity possible

BUSINESS AND DAILY LIFE WITH ELECTRICITY

Industries boom Opened thousands

of jobs Ready made clothing

big business due to electric sewing machine Women and children

Not all Americans received benefits

Mostly limited to cities

What are some ways that electricity change life?

TELEGRAPH AND TELEPHONE

Signaled start of communications revolution

Created big business Western Union-

By 1900, owned more than 900,000 miles of wire

Sent 63 million messages

Started in Omaha, Nebraska by Union Pacific RR and Sacramento, CA by Central Pacific RR

Most workers immigrants Irish and ChineseFinished in Promontory

Summit in what is present day Utah

Leland Stanford drove in golden spike

Elijah McCoy African American

engineer invented lubricating cup that continuously oiled the moving parts of the factory machinery

The “Real McCoy”

Transcontinental RR

TRANSCONTINENTAL RAILROAD

RR CHANGE TIME AND INDUSTRY Railroads ushered in

time zones from solar time

A faster and more practical means of transporting goods

Lower costs of production

Creation of national markets

Model for big business Professional manager

and specialized department

Stimulation of other industries

BESSEMER PROCESS Henry Bessemer 1856, patented

Bessemer machine Made removal of

impurities much easier

Made mass production of steel (production in great amounts) possible

Ushered in New Age of building
