A Technological Revolution

Technological Revolution Technology drastically changed people’s daily lives Started 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 Thomas Edison 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 Electricity Improved method for producing filaments in light bulbs George Westinghouse Alternating 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 Samuel Morse Alexander Graham Bell Patented talking telegraph in 1876 Formed AT and T with a group of partners in 1885 Signaled start of communications revolution Created big business Western Union- By 1900, owned more than 900,000 miles of wire Sent 63 million messages

Transcontinental Railroad-Choo Choo Transcontinental RR 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 Chinese Finished 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 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 Brooklyn Bridge John A. Roebling Competed in 1883 Read page 235
