Lewis Howard Latimer was an inventor and draftsman best known for his contributions to the patenting of the light bulb and the telephone. Latimer devised a way of encasing the filament within a cardboard envelope which prevented the carbon from breaking and thereby provided a much longer life to the bulb and hence made the bulbs less expensive and more efficient. This enabled electric lighting to be installed within homes and throughout streets.
