"What hath God wrought?"

The Lightbulb

  • First telegraph system built in 1843 from Washington D.C. to Baltimore
  • First transcontinental telegraph line built in 1861 by Western Union
  • Western Union was the largest telegraph provider - worth $40 million in 1866
  • Would be worth $588 million today

Early Telegraph

Telegraph and Telephone - Communication Milestones

Of course I invented it!

By stealing my idea!

"Tomorrow the hearts of the civilized world will beat in a single pulse, and from that time forth forevermore the continental divisions of the earth will, in a measure, lose those conditions of time and distance which now mark their relations."

- Times of London after first successful transatlantic cable (1858)

So who gets the credit for inventing the telegraph?

Telegraph

President Rutherford B. Hayes to Alexander Graham Bell in 1876 on viewing the telephone for the first time:

“That’s an amazing invention, but who would ever want to use one of them?”

  • Around in the early 1700s
  • By 1798 a rough system was in place in France

Samuel Morse (1791-1872)

He began work on his version of the telegraph in 1832, developed Morse Code in 1835 and 1838 he presented his idea to Congress. 62 other inventors had laid claim to the telegraph before him - but he was the first to get political as well as financial backing from the U.S. Congress.

So did Edison invent the lightbulb?

Alexander Graham Bell

No! Because we know him!

Trivia

The Problems with Lightbulbs

How did the telegraph change the world?

What was the first words ever spoken over the telephone?

What does AT&T stand for?

The Telephone

Do we know him?

World was divided into geographical regions - no knowledge of national or international events

If you can't beat 'em - join 'em!

Burning or Melting - the search was on for the perfect burner

The Problem with Cotton

Who was this famous inventor?

1765-1825

  • Easy to plant and grow and stored longer than food
  • However it contained seeds that were hard to separate from the fibers
  • The average cotton picker could only clean about one pound of cotton a day

The Steam Engine and the Advent of the Industrial Revolution

Cotton Gin

  • Factories were around before the Industrial Revolution - they just relied on horses or oxen to provide power
  • Glassmakers demanded enormous amounts of coal thus creating a demand for a more effective way

Yes it was important!

  • Worked like a strainer
  • Cotton was run through a wooden drum that had metal hooks that caught the fibers and dragged them through a mesh
  • Seeds were too big to be pulled through
  • Earliest cotton gin was cranked by hand, larger ones later could be powered by a horse and then a steam engine
  • Went from a pound a day to FIFTY pounds

What we think cotton looks like

  • Thomas Savery
  • Thomas Newcomen
  • James Watt

Cotton in the fields

1. Massively increased production of cotton - making the South a leader in cotton production which helped fuel the Industrial Revolution

2. More Cotton = More Slaves

3. Hastened the beginning of the Civil War

Factory Using Steam

What it actually looks like

United States still the leading export of cotton in the world - an advantage we gained after the invention of the cotton gin
