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
horse-drawn machine
- 1930 15-20 hours with a
tractor
- 1975 3-4 hours with
large tractors & combines
Horse-drawn 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 horse-drawn 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.
- 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
1900s Westinghouse
electric 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
maintenance 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
non-electric vacuum cleaners
- lots of non-electric vacuum cleaners were
invented in the late 19th and early 20th century--the
development of household technology 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)
the electric iron
- 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
-
GE Monitor on top
Refrigerator, 1928
- 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 maintenance, 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

- or, defining housework somewhat
differently:
- 1924-28: farm
wives
51
hours/week
- 1965-66 non-employed 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:
Eiffel Tower
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 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 Jetson's 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
