Container Summary

3 light bulbs of various sizes and designs, all undated and unidentified. The first bulb, 10.5" x 4", the largest, appears to be made of hand blown glass: a sphere with three glass protrusions, each protrusion containing a metallic disk on the end of a short metal rod; no evidence of a filament; undated, creator unknown. The second bulb, 8" x 3.25", the second largest, labelled at the top in the modern fashion "General Electric 200W 120V;" filament in tact; undated, but probably an early example of a mass produced incandescent bulb. The third bulb, 3.75" x 2", the smallest and possibly the oldest, made of hand blown glass; filament is in tact, base has bare wires; undated, creator unknown. J. Harris Rogers did experimentation with electricity and lighting in the 1870's and the 1880's, during some of which time he was Electrician of the Capitol (1877 1882), installing the first electrical lighting in the Capitol building and on Pennsylvania Avenue.
