Edison's First Lightbulb
Thomas Edison did not invent the first lightbulb, nor even the first incandescent lightbulb. He invented an incandescent lightbulb which was reliable, long-lasting, and manufacturable. Edison's first lightbulb is not viewable in any museum, however. It was broken up in the laboratory in order to find out what had made it work so well.
