The document summarizes several important scientific and technological developments between 1800-1850, including: 1) Samuel Colt patented the Colt Revolver in 1836, the first rapid fire firearm which was a major advancement in weapons technology. 2) Samuel Morse invented the telegraph and Morse code in the 1830s-1840s, allowing the first long-distance communication via wires across the United States. 3) Inventions of the electric motor in the 1830s by Michael Faraday, Joseph Henry, and William Sturgeon paved the way for electric motors to power new vehicles and devices.

Colt Revolver
• Patented in 1836 by Samuel Colt
who was 22 at the time.
• It was modified and used by the
U.S. Army in the Mexican War in
1846.
• The Colt Revolver was the first
rapid fire weapon ever invented
and thus was a great leap forward
in firearms technology.

4. Telegraph and Morse Code
Everett
• In 1832-1837, Samuel F.B. Morse
invented a feasible model of a one
wire telegraph with his two
partners Leonard Gale and Alfred
Vail.
• in 1837, the telegraph was
announced to the public.
• In 1838 Morse conceived the system
of dots and dashes now known as
the Morse Code and adopted the

5. Telegraph and Morse Code
Everett
• Congress granted Morse $30,000 to
fund his effort to wire the United
States in 1842.
• The first messages were in 1844 when
Morse displayed the telegraph by
sending the message, “What hath god
Wrought?” from the chamber of the
supreme court to baltimore’s mount
Clair train depot.
• Following railroad lines, the
telegraph eventually spread across
the United States and vastly

Electric Motor
• The creation of the first electric motors is
accredited to the British Michael Faraday,
who created a model in 1831, and to the
American Joseph Henry, who completed an
improved model in 1831.
• Henry’s model was more feasible than
Faraday's model, yet it still was not able to be
implemented in any useful way.

10. Everett
Electric Motor
• In 1832 William Sturgeon invented the first
electric motor that provided sustained
rotation.
• His device became the basis for most Direct
Current electric motors today.
• The electric motor has proved invaluable,
being used in such things as new quiet
military vehicles to cell phones.
• Without them the new push for green
vehicles would be severely hampered.

Steamboat
• As the steam engine was relatively
new technology, the steamboat did
not become successful until Robert
Fulton and Robert Livingston built
the North River Steam Boat (a.k.a.
Claremont) in 1807.
• It took the new steamboat one day
and six hours to go the 150 miles
from New York City, NY to Albany,
NY. EV

Steamboat
• Fulton and Livingston also built the
New Orleans for travel along the
Mississippi river between New
Orleans, LA and Natchez, MS in 1812.
• In 1809 John Stevens built the
Phoenix, the first steamboat to
travel in the ocean going from New
York City to Philadelphia in 13 days.
• The Savannah became the first
steamboat to traverse the Atlantic,
going from New York City to

Steamboat
• The steamboat primarily
transported sugar, cotton, and
people throughout the United
States.
• It had an exponential effect on the
economy, turning any town on the
river into a major city.

The Sewing Machine
• Elias Howe built the sewing machine in 1845.
• The machine could stitch around 250 stitches per
minute. (The fastest sewers could do about 50
per minute)
• The machine could only sew short, straight
distances at first. Elias would eventually take it to
British companies to improve it. (Specifically Isaac
Singer)
• The invention gave commercial businesses the
ability to produce more while cutting back on
workers, causing industries like clothing to boom.

John Deere’s Steel Plow
• John Deere made his first steel plow in 1837.
• The steel plow broke stubborn soil with ease
and was also light enough to be pulled by a
horse.
• John’s invention would solve westerner’s
problems of hard soil breaking their farm
equipment, allowing westerner’s to develop
their farmland.

23. Cyrus McCormick’s Mechanical Mower
Rob
Reaper
• In the 1830’s, Cyrus McCormick would create a
machine that would reap crops at astounding
rates.
• The machine would be pulled by horses, and as
the machine went over the grain it would cut it. A
revolving wheel would then lay the grain beside
it, where someone would rake it into piles.
• McCormick's mower reaper, like other machines,
reduced the amount of time it took to harvest.
This meant they could grow more crops and have
less workers.
