2. Who invented?
That’s a tough question to answer!
An invention can change things but no invention is created in vacuum.
Every invention was built on previous inventions made years, decades
or centuries ago.
It usually isn't the original inventor who gets all the credit, but rather
the inventor who made the one crucial improvement that made it
easier to use.

3. The printing press
Johannes Gutenberg, a German
goldsmith invented the Gutenberg
press, an innovative printing
machine, in the 1430s

Powered the factories, trains, and ships that helped in the
growth of industries
Thomas Savery, an English military engineer and
inventor who in 1698, patented the first crude
steam engine. Thomas Newcomen invented the
atmospheric steam engine in 1712. James Watt
improved Newcomen's design and invented what
is considered the first modern steam engine in
1765.

5. The automobile

Transformed daily life, our culture, and our landscape
In 1885, Karl Benz designed and built the world's
first practical automobile to be powered by an
internal-combustion engine.

6. The light bulb
In 1809, Humphry Davy, an English chemist,
invented the first electric light. In 1878, Sir Joseph
Wilson Swan, an English physicist, was the first

filament. In 1879, Thomas Alva Edison invented a
