African-American Inventor Lewis Latimer Magnet

This is a replica of a vintage black and white photograph of African-American inventor Lewis Latimer. Latimer drew the drawings that went with Alexander Graham Bell patent application for the telephone. He invented an improved filament for incandescent light bulbs, which made the light bulb to be lit long enough for practical use. Eventually, he went to work for Thomas Edison. Latimer was valuable to Edison due to his familiarity with both patents and electrical engineering.
