But are all these inventions changing our lives as much
as peoples lives were changed by the 1920s by the
telephone, the automobile, the airplane, etc.?
1900-1920 was a period of particularly revolutionary new
technologies
This book focuses on that change, trying to give you a
sense of how people's lives changed with the coming of the
modern world.
- how did the people in the book experienced life
differently from people in earlier times or the way we
do today
- some technological change follows a trend, but
sometimes you get unexpected revolutionary change--the
trend direction changes
- how has technology changed the way we live in
your grandparents lifetimes?
- how will technology change our lives in the next
20 or 30 years?
- we may be in another time of revolutionary change
in social experience, like the one that began the
modern era
this book focuses on people who were enthusiastic about
the modern era
what about people who rejected modernism--accepted new
technologies but didn't want any social change that might
result
fundamentalist Christianity developed in the early 20th
century as a rejection of modernism
Chapter 1: Heinrich Lienhard came to
the United States from Switzerland in 1843 at age 21 and
ended up in San Francisco.
San Francisco in 1847
What technologies were coming in in the 1840s?
- the industrial revolution in the United States
was in the takeoff phase--big textile
factories were spreading in the northeast
- plantations worked by slaves are moving west to
Alabama, Mississippi, Louisiana, Texas, and becoming
more efficiently organized to make maximum profits
- steam power was just beginning to grow in
importance, and the steamboat was revolutionizing
river travel
- experiments as early as 1780s both
in England and American, but the need was greater in
America.
- a lot of varied speculation, including
an 1785 paper by Benjamin Franklin in which he
concluded that paddlewheels were inefficient and
proposed jet propulsion.
- This put John Fitch on the wrong
track--his mechanic convinced him not to try water
jets but he worked on crank and paddles
instead of paddle wheels. he did demonstrate a
boat in 1787 and run boats on the Mississippi in a
commercial operation as early as 1790, although he
ultimately failed.
- Robert Fulton trained in England and
France (he had gone to London originally to study art
but ended up studying civil engineering). He
built his first commercially successful steamboat for
the Hudson starting operation in 1807 (with a promise
of a 20 year monopoly from the NY legislature) with a
133 ft. boat called the Clermont
with twin sidewheels. He
used a Watt engine and built his boats for passenger
comfort and speed.
The Clermont, from an early history of steam power
by Thurston
- He also ran boats on the Mississippi,
but they didn't do very well.
- Other engineers solved the problems of
adaptation of the steam boat to western
conditions .
- The key innovation was the
high-pressure steam engine invented by Oliver Evans in
1801. Dominated western steamboats because less
fouled by muddy water.
- Gradual development of shallow hull
and flat bottom, upper decks, horizontal engine
(easier to connect to a stern paddlewheel.
- Extremely profitable--sometimes 100% a
trip. Henry Shreve did the best job of putting
all these innovation together and also invented the snagboat
. clearing
snags
- The steam boat was the first time the
United States took the lead in developing a major new
technology
- a small steam boat came to San Francisco in 1847
and no one took it seriously (listen
to this story), but two years later Heinrich
could travel from San Francisco to Panama and from
Panama to the east coast by steam-powered
packet (ocean-going boat)
- the first sewing machine had recently been
patented
- Norbert
Rillieux, born a free person of color in New
Orleans in 1806 (his father was white, his mother a
free woman of color)
- studied engineering in France and
returned to New Orleans in 1833 bringing with him a
major invention,
an energy-efficient way of evaporating cane juice
into sugar. This transformed the sugar
industry the way the cotton gin transformed the
cotton industry
- free blacks were 25% of the population in New
Orleans in the early 19th century and had more
opportunity than free blacks in other parts of the
south. Norbert's brother Edmond
became superintendent of the New Orleans water works
- why do you think we hear more about Eli Whitney
than Norbert
Rillieux?
- enslaved Africans brought agricultural and
iron-smelting technologies with them to North
America
- if they had any room to innovate someone else
probably took credit
- New Orleans was particularly diverse and
inventive
- The Smithsonian Institution was
created--an Englishman who had never been to the
United States left his money to the U.S. government to
create a center for scientific research
- Louis
Agassiz, a well trained European naturalist
(biologist) moved to the United States to teach at
Harvard
- he was a creative scientist but resisted some
of the new ideas of science, including evolution
- he argued that Africans were created separately
from whites, were not descendents of Adam
What is the larger pattern here?
- The industrial revolution had come to the United
States
- The US was trying to catch up with Europe
- Americans borrowed European technology and
changed it into something to fit American conditions
- this and and greater openness to new ideas
resulted in very rapid progress
- Americans were very open to new ideas and
interested in new technology because there was a
shortage of labor (particularly skilled labor)
guns were being made with interchangeable parts (this
is called the American
System of Manufacture)
- traditionally one craftsman made most of a gun,
one by one by hand
- Eli Whitney, inventor of the cotton gin, proposed
making guns by mass production
- machines cut out uniform parts, then the gun just
has to be assembled
- the US government supported development of this
technology for faster production and interchangeable
parts
- expanded into other industries starting in the
1850s
- made new technologies possible
- mass production met American needs
How did the west get from cowboys and indians to modern?
- very quickly
- the town of Telluride tried electric power in 1891, by the
early 1900s the company was supplying power to 3
states
- consider the example of Elizabeth
Fleischman: without training built her own x-ray
system for medical diagnosis
- x-rays are an example of new technology that no
one expected
The Columbian
Exposition of 1893--a major worlds fair in Chicago
- worlds fairs were a lot like Disney World and
Epcot put together, but were temporary rather than
permanent (if you have been to Epcot, how accurate do
you think its prediction of the future is?)
- the Columbian Exposition celebrated technologies
of the time such as steam engines and telephones, but
didn't pick the upcoming winners well.
Completely missed the automobile, which had been invented
in 1889.
- An 1887 prediction of the future is available on
the web: Looking
Backward, by Edward Bellamy.
