    1. The Second Industrial Revolution 1876-1900

    2. Steel Steel is iron that is made stronger by heating it and adding other metals. Steel was expensive and challenging to make. Steel could only be made in small amounts.

    3. Henry Bessemer In the 1850s Henry Bessemer of Great Britain develops a way to make steel quickly and cheaply. By blasting hot air through melted iron to quickly remove the waste material, what used to take days to make a ton of iron ore into Steel now only takes 10-20 minutes

    5. Making Steel

    6. Riding the Rails When the price of steel dropped from $100 a ton to $18 a ton Tracks in America jumped from 30,000 miles in 1860 to 193,000 in 1900. 1860 it took two days and 17 train changes to get from NYC to Chicago By 1870, NYC to Chicago took one train and half a day.

    11. Inventions Dr. Benjamin Silliman Jr. creates Kerosene made from crude oil Kerosene is used for cooking, heating and home lighting Demand for Crude Oil increases 1859 Edwin. L Drake invents a way to pump crude oil from the ground Oil is first pumped from a well in Titusville, PA Ohio, PA, and West Virginia first oil producers

    12. Dr. Benjamin Silliman Jr

    13. The Process of creating Kerosene Produces gasoline an Unwanted by product at the time

    14. Thomas Alva Edison Edison creates the first “think tank” centered in Menlo Park, New Jersey Called “invention factory” Edison held more than 1,000 patents A Patent is an exclusive right to make or sell an invention

    15. Invention Factory 1890

    16. Invention Factory 1929 now

    17. Chemical Lab at Menlo Park

    18. Edison’s Electric Car 1910

    19. Edison creates battery powered miners lights 1923

    20. San Francisco 1895 Phonograph Parlor

    21. 1879 Edison with help from the invention factory create the first electric light bulb Problem very few homes had electricity Edison builds a power plant Supplies power to dozens of buildings in NYC in September 1882 His power plant could only send power over a short distance

    23. Electricity Link

    24. Westinghouse George Westinghouse builds a power plant His could send power over great distances Westinghouse and Edison compete around the country to sell their power plants Westinghouse wins Cities now run street cars that run on electric power. San Francisco is the last major city to still have a running street car system

    25. Communication 1861 East and West coast connected with telegraph wires 1866 America and Great Britain are connected with a telegraph wire that lays on the bottom of the Atlantic ocean Telephone is invented in March 1876 First named “speaking telegraph”
