Answer:

developing the phonograph and motion camera

Explanation:

Thomas Edison was an American inventor born on February 11, 1841 in Milan, Ohio. Throughout his life he patented 1,093 inventions.

His first great invention was the phonograph in 1877, it recorded sounds creating indentations on a drum wrapped within a foil. The first thing he recorded was his voice saying "Mary had a little lamb."

Later, he worked with William K. L. Dickson, they wanted to link the phonograph with a zoetrope wich strung together series of images giving the sensation they moved. They succeeded and constructed a motion picture camera wich they named "The Kinetograph" in 1891.
