By the early 20th century engineering was
triumphant--Americans looked to rationality and efficiency to make life
better. More, faster, better was the theme of the time.
But questions began to be raised. Cowan ch. 8 is
important for its discussion of the impact of technological change on
the experience of work.
Agriculture:
:
Scythe
with cradle
Labor involved in growing 100 bushels of wheat
- 1830 250-300 hours by hand
- 1890 40-50 hours by horsedrawn
machine
- 1930 15-20 hours with a tractor
- 1975 3-4 hours with large
tractors & combines
Horsedrawn agricultural machines developed in the
mid-19th century were a revolution at least as significant as the
tractor
1837 John
Deere produced a wrought iron plow with steel cutting edge for
sticky prairie soil--his factory produced about 1000 in 1846, about
10,000 in 1857. Harrows, grain drills, cultivators, and
mechanical threshers (John and Hiram Pitts, 1837) come into use in 1840s
McCormick Reaper
Two workable horsedrawn reapers
patented in the 1830s by Cyrus
McCormick (some of the ideas apparently came from a slave
he owned) and Obed
Hussey , both using vibrating blades, in Hussey's case moving in a
slot in a series of guide teeth. The McCormick reaper could cut
15 acres of wheat a day. A man with a scythe and cradle could cut only
3 acres. Not widely used until about 1855.
- McCormick didn't have the most uniform or
satisfactory product but he moved his factory from Virginia to Chicago
to be nearer the demand while Hussey stayed in Baltimore.
- McCormick succeeded by advertising and
demonstrations, and by developing exclusive dealerships and selling
machines on credit.
- Manufactured by regional franchises until 1851,
at which point his production was 1000 per year. Even his
steam-powered plan in Chicago in 1850 depended on skilled workers, not
special-purpose machines.
- Annual new model made manufacturing innovations
difficult and meant replacement parts were an incredible headache--this
wasn't a conscious marketing strategy but a combination of improvements
and meeting the expectations of farmers.
- Even in the 1870s, factory manager Leander
McCormick did not want to expand production and was notably
unknowledgeable about machine tools--ordered things that did not exist
and asked for parts that were not normally supplied (Chicago too far
from New England, for one thing).
- Only introduced mass production techniques in
1880, when Cyrus kicked out Leander and hired Lewis Wilkinson, who had
worked at both the Colt Armory and the Wilson Sewing Machine
company. Production increased fivefold by 1902.
Widespread use of these machines came with Civil War
- labor shortage and high prices resulting
from the civil war--farmers had cash to buy machines.
- When prices went down after the war farmers had
to expand and mechanize to keep up. Farm workers 64% of labor
force in 1850, 49% in 1880.
- Machine farming developed on a large scale with
settling of western Great Plains, 1870-1890.
- Rainfall of less than 15 in/yr and required wells
50-500 feet deep (windmills scarce until 1900). Open range pretty
much gone by 1890s; ranching took advantage of barbed wire
(invented in 1874) to fence grazing land.
Glidden's
1874 barbed wire design
- 1870s brought first attempts at large-scale,
technology-intensive farming.
- Took advantage of new varieties of wheat
(particularly Russian) that could grow as winter wheat in cold climates.
- Dry farming techniques--planting in deep
furrows (dust mulch).
- Experiments by people such as Oliver
Dalrymple in mid to late 1870s--Grandin Bonanza, a farm of 61,000 acres
worked by 200 pairs of harrows, 155 binders, 16 threshers, combines
pulled by teams of 30-50 horses and mules or by steam tractors.
But many large farms went bankrupt in the droughts of 1885-1890.

Enthusiasm continued for steam tractors despite
usefulness only on hard soils (14 hp steam engine weighed 12,000 lbs.).
- By 1900 5000 steam tractors made per year.
- Required many men to operate and much carrying of
supplies, not to mention danger of setting fields on fire with sparks
from the engine.
- Mass production of gasoline powered tractors
began in 1903.
Back to the
history of Mass Production
Historical steps:
Where the assembly
line wasn't possible, factory owners used Scientific
management :
- Frederick
Winslow Taylor --proper Philadelphian who went to work for a
machine shop with the idea of working his way to the top.
- he was appalled by how inefficient the workers
were and set out to rationalize them.
- In 1895 he introduced the differential piece
rate--you got a lower rate if you worked slower.
- Taylor wanted not just to reward the worker but
to tell him how to do the job--time studies. Also introduced high speed
tool steel and patented improved metal cutting machines. (Taylor's
classic book is available on the web at: The
Principles of Scientific Management )
- Frank
B. Gilbreth , who joined Taylor in 1907, extended this to motion
study--watching how the worker moved and showing him how to eliminate
waste motion
- his partner and wife, Lillian Gilbreth
, realized that worker resistance was still a key issue and pioneered
industrial psychology (they also had 12 children and raised them
efficiently, as chronicled in the book and the 1950 film Cheaper by
the Dozen)
- Scientific management was applied to skilled
workers, not just workers on assembly lines
a machine
used today in evaluation of workers
How did workers feel about all this?
- Ford's workers were initially not happy with the
assembly line initially--turnover reached 380%
- Starting in 1914 Ford paid twice the going wage,
and found people eager to work under those terms
- Taylor thought his system would help workers, but
they hated the lack of control, and in some cases went out on strike
against time study (such political
agitation that in 1915 Congress outlawed Taylorism at government
arsenals)
- skilled workers were loosing their position to
unskilled workers with machines:
- Cowan gives the example of carpenters using
factory-made components
- new office machines revolutionized the office
work force--in 1870 men made up 97.5% of the clerical labor
force. But typewriting became a women's job
. By 1890 women were 21% of clerical labor force, by 1920
50%. Some even argued that women were better with machines than
men.
- Pride in work (my list is based on Cowan p. 187):
- relatively high wages
- work that is not mind-numbingly repetitive
- some control over daily schedule
- some control over quantity and quality of
what is produced
- skills that take time to learn are valued
- some job security because of time it would
take to train a replacement
technology tends to take these away
There were other people besides workers who had
doubts about the modern, technology-based world:
- World
War I showed the dangers of more efficient weapons.
- The conservation
movement worried that we would run out of resources.
- some people in the 1920s feared that traditional
values were being lost, which is why the first major protests over the
teaching of Darwin happened then (see Scopes
Monkey Trial )
- The Great
Depression of the 1930s made those doubts a lot more common,
because a lot of the problem was overproduction.
Consider also how domestic
work was changing:
Is technology liberating?
- That may not depend on the technology, but rather
on how society's values affect how it is put to use
- I don't mean to imply that technology is
value-free, but household technology is an example of a general area of
development that could have been liberating but instead was used to
reinforce existing values
- this analysis of household technology is valid
only for middle-class American women--lower class women have had
neither the technology to help them with their housework nor the choice
of whether to work outside the home or not
- Starting in the second half of the 19th century,
the technology used by the average middle-class housewife has changed
dramatically.
cast iron
range
Cooking:
- cast iron range introduced about 1830, universal
by the end of the century
- the only appliance in an 1899 model kitchen
- study that same year by Boston School of
Housekeeping: in six days required 5 hours 26 minutes of maintenence
and took 292 pound of coal
- this shows a clear advantage for the gas or
electric range
- a gas or electric range saved hard physical labor
and didn't heat up the kitchen
- but electric ranges were sold primarily as
modern, as one ad said: "It is so modern, It's so clean, so cool, so
efficient."
history of the vacuum
cleaner
- lots of non-electric vacuum cleaners were
invented in the late 19th and early 20th century--the development of
household techology was not simply a result of the availability of
electricity
- central vacuum systems had a brief popularity
around the turn of the century
Hoover 1907
- Hoover and similar machines
- the first portable electric vacuum cleaner
was introduced in 1907
- advertised in 1910 "Tell your husband you
want it for Christmas. He has every convenience for his work:
typewriter, adding machine..."
- another 1910 advertisement "doing much of the
work of a maid and doing it infinitely better than human hands can do"
Washing
clothes
- before mechanization the first task was to carry
water. The tools were the washboard and wringer
- initially the process was simply mechanized, with
some externally-powered machines introduced in the late 19th century
and electric ones coming on the market about 1910
Maytag Washer
hooked to farm service engine
- 1920 electric washing machine ad: "His happiness
as well as hers. The man in the house welcomes Bluebird too--and
delights in dispelling the gloom of washday. For with Bluebird
comes happiness--the happiness of a well-ordered household plentifully
supplies with clean clothes." (note rising standards)
- by 1940 washing machines were affordable and
widespread, but they still weren't automatic--the top-loading automatic
washing machine was only introduced in 1947
Ironing:
- heating irons on the stove was another unpleasant
task in the summer
- electric irons were introduced in the 1890s and
were appreciated as a big improvement--some utilities gave them away
free to promote use of electricity (sort of like cell phones today)
- in the days before permanent press clothing
ironing was such a burden that ordinary families actually bought large
ironers
ironer
the story of the refrigerator
is fascinating from the technical point of view
-
- ice was delivered to homes in cities and towns,
so iceboxes
were fairly satisfactory
- refrigerators were introduced in the 1910s, but
did not catch on until the late 1920s
- when GE decided to introduce an electric
refrigerator they carefully selected the technology that cost less to
build, required more mainenance, and used more electricity.
What was the impact of all this new technology?
- The statistics are certainly not exact, but the
evidence we have shows that the amount of time spent on housework by
women not employed outside the home has not decreased with the
introduction of household technology
Hours per week spent
on housework
| 1928 |
Oregon town wives |
63.4 |
| 1928 |
farm wives |
61 |
| Post WWII |
farm |
60.6 |
| Post WWII |
small city |
70.4 |
| Post WWII |
large city |
80.6 |
- or, defining housework somewhat differently:
- 1924-28: farm
wives
51 hours/week
- 1965-66 nonemployed urban
wives 55 hour/week
- today
Why?
- rising standards: changing clothes every day
instead of once a week, discovery of germ theory of disease in late
19th century
- household technology replaced servants--paid
servants 99 per 1000 population in 1900, 58 per 1000 population in l920
- work expands to fill the time available. A
new ideology of housework was developed to keep housework a full-time
job despite machines that made it easier
- home economics
: housework is a job worthy of an intelligent woman (scientific
management, Lillian Gilbreth, efficiency, rationalization)
Conclusion
- Technology can be used to reinforce existing
values or to change them
household technology for many years did not
liberate women
- When we choose our technology for what it can do
for us, what goals do we choose and who does the choosing?

Skyscrapers and urbanization:
when a great fire burned central Chicago in 1871, people
realized the city would need to be rebuilt in a more fire-proof way
this led Chicago to become the first city to start to build taller and
taller
Several technologies were needed to make this possible:
Steel Frame:
- the earliest taller buildings had load-bearing
stone walls, but the taller the building the thicker the stone wall
needs to be at the bottom
- the Eiffel Tower shows the pure steel frame--picture to right
- Steel
frame construction developed about 1890 for the skyscrapers of
Chicago. First steel frame was 1885 for a 9 story building, then 1892
for 21 stories
- the workers
who built these frames were in many cases Mohawk
indians because they had little fear of heights
Foundation:
- concrete pillars that extended down to bedrock
- or steel piles (vertical beams) are forced into the ground
by a pile driver
Elevator
- people won't accept tall buildings without a safe way to get
up and down
- the hydraulic
elevator was the first practical technology, later replaced by
electric elevators
- Elisha
Graves Otis invented a reliable elevator
safety brake, making the elevator practical for passengers
- escalators didn't catch on until the 1930s, but think of
what it meant to people to have a moving stairway--we no longer had to
do the work ourselves
tall buildings weren't necessarily cost efficient but they became
a sign of pride
- Leiter Building--early steel frame
construction
- many of the early skyscrapers still had traditional
decorations on the outside
- when a 26 story building was build in Manhattan many said
that the maximum height had been attained, but 1912 a 55 story building
was built and in 1932 the Empire State Building was 86 stories.
The World Trade Center was 110 stories--more than 1/4 mile.
- skyscraper history and economics
in New York
Between 1870 and 1920 New York City expanded from less
than a million to 5 1/2 million population and from 22 to almost 300
square miles. Density also increased in the center city with the
invention of the elevator and steel frame construction. People
began to imagine how far the skyscraper might go
King Gillette, who started the first company to make disposable
razor blades, also wrote a book
about how the United States should be organized:
- forget capitalism, which is full of wasteful competition,
and plan everything out rationally
- cooperation should be the basis of society, selfishness
would be eliminated
- everyone would live in one gigantic city and eat in common
dining halls--think how inefficient single family homes are
- if this seems ridiculous consider the proposal that the best
thing we could do for the environment would be to all live in cities,
and let the rest of the land go back to wilderness
The vision of the future in which we lived in giant
cities interconnected by skyways was common in the early 20th
century, longer in science fiction
- pictures of future cities usually showed many levels of
highways or walkways connecting the buildings
- an architectural movement called futurism
sought to reject the ideas of the past and embrace technology
- The Jetsons cartoon is a classic example
- For performance credit watch either H. G. Wells, "Things to
Come," or Fritz Lang's "Metropolis" and write about how the film you
watched expresses modernist ideas

the city in the 1927 film Metropolis
Why didn't we get the titan city future?
- the movie "Metropolis,"
set in the year 2026, showed that the dream of the future was
ignoring the lower depths--the machines and workers making the city
possible
- H.G. Wells made this point in The Time
Machine and When the
Sleeper Wakes
- the luxurious city in the air is made possible by people
working in horrible conditions below it
- the giant city became a threatening image--think Blade Runner
But
we did get modern architecture
- Modernist architects started to simplify the building
- first they focused on what was functional--instead of
decoration, simple functional forms would be a new standard of beauty
- then they started exploring what they could do if they threw
out old assumptions
