Transcript of A Technological Revolution
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
Samuel MorseAlexander Graham Bell
Patented talking telegraph in 1876
Formed AT and T with a group of partners in 1885
TRANSCONTINENTAL RAILROAD-CHOO CHOO
Railroad that extended from coast to coast
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
