Who invented the lightbulb? If you said Thomas Edison, you're only partially right. In fact, there have been many light bulbs invented with many different technologies throughout history — it's just that Edison was successful enough to make his mark in textbooks. But there's a lightbulb inventor that at least one 1890s newspaper columnist considered to be among the ranks of Edison and Nikola Tesla, and you've probably never heard of him. His name was Daniel McFarlan Moore.
