Inventors during the late
1800s
Elijah McCoy
• McCoy invented the
oil dripping cup for
steam engines. It
was a way to lubricate
the engine. Many
people tried to copy it,
But his invention
worked so well that
people started asking
for the “real McCoy”
Thomas Edison
• Thomas Edison invented
many things that changed
life of the average
American. Probably the
most important area he
worked in was electricity.
Edison not only invented
the light bulb, he also
came up with many other
mechanical uses for
electricity.
Lewis Latimer
• Thomas Edison may
have invented the
light bulb, but he
couldn’t have done it
without the carbon
filament that Lewis
Latimer invented.
Alexander Graham Bell
• If you like talking on
the phone thank
Alexander Graham
Bell. Without him you
might never get the
latest gossip.
