7. 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

8. 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?

Signaled start of communications revolution
Created big business
Western Union-
By 1900, owned more than 900,000 miles of wire

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”

11. Transcontinental Railroad

12. 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

13. Bessemer Process Henry Bessemer 1856, patented Bessemer machine

Made mass production of steel (production in great amounts) possible
Ushered in New Age of building
Brooklyn Bridge
John A. Roebling
Competed in 1883
